Prioritizing Zoonoses for Global Health Capacity Building-Themes from One Health Zoonotic Disease Workshops in 7 Countries, 2014-2016

One Health implementation: A systematic scoping review using the Quadripartite One Health Joint Plan of Action

Background

One Health (OH) recognizes the interconnectedness of humans, animals, and their shared environment and mobilizes multiple sectors to achieve sustainable and optimal health outcomes. We synthesized current OH implementations at global, regional, national, and local community levels using the OH Joint Plan of Action (OH JPA) developed to enhance best practices in OH implementation.

Methods

We applied the OH JPA Theory of Change, supported by three pathways mapped out across six action tracks to guide our review. Searches were conducted in PubMed, Embase and Scopus. Eligibility of studies was based on implementation of OH undertaken across two or more sectors within the human-animal-environment interface. Selection was guided by the PRISMA-ScR.

Results

Of the 54 studies, 77 unique programs reported OH implementations, and of these, 42 (54.5 %) involved human and animal sectors only. No studies involved the environment sector and its impact on human-environment or animal-environment. The majority (90.9 %) of programs incorporated at least one aspect of policy, legislation, advocacy and financing (Pathway 1). Capacity development, community engagement, multisectoral coordination, collaboration or communication was identified in 96.1 % of programs (Pathway 2). Data, evidence and knowledge featured in 60 % of OH initiatives (Pathway 3).

Conclusion

Pathway 2 was the most engaged pathway building the foundation for OH implementation and action. There is opportunity for further growth concerning community engagement, monitoring and evaluation strategies with enhanced future investment for implementation of community-centric and risk-based solutions. Furthermore, it is important to foster better understanding of environmental issues and to build capacity for the environment sector to be better represented in the implementation of OH.

Prevalence and incidence of zoonotic diseases in South Asia: a systematic review protocol

OBJECTIVE

This review aims to estimate the prevalence and incidence of zoonotic diseases from studies of populations from South Asia (Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka).

INTRODUCTION

South Asia is of notable importance in terms of the prevalence and incidence of endemic zoonoses, as well as its role as a focal point for emerging zoonotic diseases.

INCLUSION CRITERIA

Studies reporting on populations residing in the 8 South Asian countries, irrespective of age/gender, will be considered. Primary outcomes will include studies estimating the prevalence and incidence of zoonotic diseases in South Asia. Secondary outcomes will include the burden of zoonotic diseases, including emergence and reemergence.

METHODS

Databases including PubMed, Embase (Ovid), Scopus, and Web of Science Core Collection, as well as government websites, reports of multilateral agencies, and gray literature will be searched. Titles/abstracts, full screening, and critical appraisal of included studies will be conducted by 2 independent reviewers with adjudication by a third author. JBI guidelines for prevalence and incidence studies will be used to extract data from included studies. Critical appraisal of included studies will be conducted using the standard JBI checklists. Where feasible, statistical meta-analysis will be conducted to report the proportional representation related to prevalence and incidence using forest plots, along with the 95% CI. Publication bias will be assessed using Egger's test and funnel plots, if possible. Subgroup and sensitivity analyses will be conducted using standard methods. Where statistical pooling is not possible, tables and figures will be used to present the results in a narrative synthesis.

A framework for quantifying the multisectoral burden of animal disease to support decision making

Animal diseases have wide-ranging impacts in multiple societal arenas, including agriculture, public health and the environment. These diseases cause significant economic losses for farmers, disrupt food security and present zoonotic risks to human populations. Additionally, they contribute to antimicrobial resistance and a range of environmental issues such as greenhouse gas emissions. The societal and ecological costs of livestock diseases are frequently underrepresented or unaddressed in policy decisions and resource allocations. Social cost-benefit analysis (SCBA) offers a comprehensive framework to evaluate the broad impacts of animal diseases across different sectors. This approach aligns with the One Health concept, which seeks to integrate and optimize the health of humans, animals and the environment. Traditional economic evaluations often focus narrowly on profit maximization within the livestock sector, neglecting wider externalities such as public health and environmental impacts. In contrast, SCBA takes a multi-sectoral whole-system view, considering multiple factors to guide public and private sector investments toward maximizing societal benefits. This paper discusses three separate sector specific (Animal health, Human health, Environmental health) methodologies for quantifying the burden of animal diseases. It then discusses how these estimates can be combined to generate multisectoral estimates of the impacts of animal diseases on human societies and the environment using monetary values. Finally this paper explores how this framework can support the evaluation of interventions from a One Health perspective though SCBA. This integrated assessment framework supports informed decision-making and resource allocation, ultimately contributing to improved public health outcomes, enhanced animal welfare, and greater environmental sustainability.

Effective community engagement in one health research in Sub-Saharan Africa: a systematic review

BACKGROUND

The one health (OH) approach, linking human, animal, and environmental health, relies on effective community engagement (CE), education, stewardship, and effective regional and global partnerships. For real impact, communities should be at the centre of research agenda setting and program implementation. This review aimed at synthesizing empirical evidence on how communities are involved in one health research. Specifically, the review aimed at documenting the extent of community involvement in one health research, as well as to identify the barriers and facilitators to effective community engagement in one health research in sub Saharan Africa.

METHODS

The study was a systematic review conducted using the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Empirical peer-reviewed research articles on community engagement in one health research published from January 2000 to September 2023 in English or French were retrieved from seven databases: MEDLINE, EMBASE, CINAHL, Cochrane Library, WHO Afro Library, the National Institute for Health Research, and African Journals Online databases. The extracted data from the included studies were analysed using a thematic synthesis approach.

RESULTS

The final review and synthesis included eight studies. The extent of CE in the one health research approach is quite limited. Two main best practices of CE in OH research were: 1) Awareness raising on OH research through social mobilization, rural outreach sensitization, and wide community assembly and 2) Building local capacity through community-based OH Training and Leadership workshops. The barriers to effective CE included: inadequate community research literacy levels, contextual disparities in CE, inadequate dissemination of research findings, language barriers and ineffective and uncoordinated stakeholder involvement.

CONCLUSION

The review underscores the importance of effective CE in one health research. The best practices for CE in one health research are raising awareness and co-creation which should guide future initiatives. There are cultural, geographical, linguistic, and educational constraints that pose barriers to CE, requiring a more integrated and community-centric approach to one health research in SSA. An effective CE in one health research through this approach will ultimately lead to more effective responses and control of zoonotic disease outbreaks.

Zoonotic diseases awareness and food safety practices among livestock farmers in Nepal

Interactions between humans and livestock could increase the risk of zoonotic disease transmission. In addition, limited knowledge of zoonoses and foodborne diseases among livestock farmers could heighten the risks of foodborne illness and outbreaks of zoonotic diseases. This study evaluated the awareness of zoonotic diseases and preventive practices for zoonotic and foodborne diseases among livestock farmers of the Chitwan, Rupandehi, and Tanahun districts of Nepal by conducting a cross-sectional survey of 280 livestock farmers. They were recruited using the purposive sampling method from October to December 2022. Descriptive statistics revealed that most (72.1%; n = 202/280) livestock farmers were aware of zoonosis. None of the farmers knew about the zoonotic nature of leptospirosis. Two-thirds of pig farmers (67%; n = 12/18) were aware of zoonotic transmission of swine flu, and more than half of the poultry (58%; 50/86) farmers knew about zoonotic avian influenza. The majority of the farmers who had dogs (83%) and cats (89.4%) in their homes or farms knew that rabies can be transmitted to humans from dogs or cats. The multivariable logistic regression analysis revealed that farmers from the Rupandehi district (aOR: 5.56; 95% CI: 2.18-14.22) and Chitwan (aOR: 6.52; 95% CI: 2.46-17.25) had a higher odds of having good preventive practices than those from Tanahun. Also, farmers who had no sickness in the past 6 months after consumption of animal products were three times (aOR: 2.98; 95% CI: 1.48-6.01) more likely to have better practices. Furthermore, secondary education (aOR: 3.64; 95% CI: 1.41-9.44) was a significant positive predictor of good zoonotic diseases and food safety preventive practices. Our study underscores the necessity to enhance Nepalese livestock farmers' awareness and practices regarding zoonotic and foodborne diseases. It emphasizes the importance of understanding risks, effective behavioral change strategies, and engaging farmers in developing zoonotic disease and foodborne illness prevention programs.

One health assessment of farmers' knowledge, attitudes, and practices (KAPs) on zoonoses in Bangladesh

In Bangladesh, farming serves as a key livelihood, leading to a higher risk of zoonotic diseases due to frequent animal interactions and traditional practices. The study aimed to assess the knowledge, attitudes, and practices of livestock farmers regarding zoonotic disease outbreaks. A cross-sectional study was conducted with 658 livestock farmers from randomly selected regions in Bangladesh from April to June 2024. The participants included farmers with at least two livestock animals and ten or more birds on their farms. Among livestock farmers, 89.06% were male, mostly aged 30-45, but predominantly from non-science educational backgrounds. The survey revealed significant knowledge and practice gaps regarding zoonosis, with only 11.55% possessing good knowledge and 37.54% demonstrating good practices. Farmers with a science education had higher KAP scores. Most avoided consuming raw animal products, although 23% lived in close proximity to animals. Logistic regression identified factors influencing KAP, including rearing systems, farming experience, pet ownership, and biosecurity training. The study found that farmers lack adequate knowledge and practices regarding zoonosis, despite exhibiting a positive attitude. The study emphasizes the need for targeted educational programs and a collaborative One Health approach to improve zoonotic disease control, particularly among less educated farmers, to enhance public health and economic outcomes.

Enteric Pathogens in Humans, Domesticated Animals, and Drinking Water in a Low-Income Urban Area of Nairobi, Kenya

To explore the sources of and associated risks with drinking water contamination in low-income, densely populated urban areas, we collected human feces, domesticated animal feces, and source and stored drinking water samples in Nairobi, Kenya in 2019; and analyzed them using microbial source tracking (MST) and enteric pathogen TaqMan Array Cards (TACs). We established host-pathogen relationships in this setting, including detecting Shigella and Norovirus─which are typically associated with humans─in dog feces. We evaluated stored and source drinking water quality using indicator Escherichia coli (E. coli), MST markers, and TACs, detecting pathogen targets in drinking water that were also detected in specific animal feces. This work highlights the need for further evaluation of host-pathogen relationships and the directionality of pathogen transmission to prevent the disease burden associated with unsafe drinking water and domestic animal ownership.

Application of the One Health Surveillance (OHS) Matrix to Evaluate the Disease Surveillance Systems in Gujarat, India: A Policy Content Analysis

An effective disease surveillance system can detect outbreaks of emerging zoonotic diseases early and allow the system to respond immediately and control the epidemic. Gujarat is a western Indian state with a population of more than 65 million humans and 26 million livestock, and it has the respective surveillance systems under the Department of Health & Family Welfare for humans and the Department of Animal Husbandry for animals. A veterinarian is placed on establishing cross-sectoral collaborations between these systems, but the joint collaborative activities and their effect on the early warning response are least understood. This provides an opportunity to conduct a secondary policy content analysis study using the One Health Surveillance Matrix (OHSM). The aim of this study was to evaluate the level of collaboration among human-animal disease surveillance systems for zoonotic disease in Gujarat, India. This study findings highlight a few gaps in the human health surveillance system, such as data sharing, sampling, outreach to decision-makers, and external communication, while the animal health surveillance system exhibits deficiencies in the data dissemination to decision-makers, management and storage of data analysis, interpretation of data, and external communication as per the OHSM evaluation. Despite major differences, there is a possibility of developing the One Health Surveillance system in Gujarat, India which is profoundly documented in this study.

Disease X and COVID-19: turning lessons from India and the world into policy recommendations

Disease X is caused by pathogen X, an unknown infectious agent that can potentially trigger an epidemic or pandemic. Pathogen X might be any pathogen, including bacteria, viruses, parasites, fungi, and prions. WHO uses the term 'Disease X' for any new emerging disease caused by an unknown pathogen X. Disease X stands for any possible future pandemic in WHO's shortlist of high-priority diseases. This review looks at the manifestations of the recent COVID-19 epidemic as the first Disease X to evaluate what has happened and to learn from what went wrong in India and worldwide. To this end, a summary is presented of response measures by governments, often lacking flows of information, discrepancies in the views of experts and decisions of policymakers, and undesirable variations in individual and collective behavior and their consequences. The elements of combating Disease X in a world with considerable inequalities in relevant knowledge, expertise, information, quality of governance, and financial possibilities are discussed. Based on this, recommendations are given for an innovative global pandemic preparedness system.

Helminths of free-ranging dogs and cats in an urban natural reserve in Mexico City and their potential risk as zoonotic agents

In the Reserva Ecológica del Pedregal of San Ángel, located in the south of Mexico City, Mexico, free-roaming dogs and cats coexist with 148 bird, 33 of mammal, 23 of reptile and seven amphibian species, that represent a remnant of the original fauna of the Mexican Plateau. The negative impact that dogs and cats have on local fauna is unobjectionable, however, the role that these introduced vertebrates play as potential transmitters of infectious diseases for native fauna and humans, is much less understood. Information about parasitic infections in native and introduced animals in this location is scarce. In order to ameliorate this lack of information, the objective of this study is to characterize the helminth fauna of the free-ranging dogs and cats of the ecological reserve. Between 2018 and 2023, 36 Felis silvestris catus and 7 Canis lupus familiaris were studied from the helminthological perspective. Endoparasites were obtained from the digestive tract and were identified to the species level using morphological and molecular evidence. Hosts were parasitized by eight species of helminths: in cats the cestodes Hydatigera taeniaeformis, Mesocestoides sp., Taenia rileyi and the nematode Toxocara cati were recorded, while in dogs, the cestode Taenia pisiformis and the nematodes Ancylostoma caninum, and Uncinaria stenocephala were found. The only species shared between cats and dogs was the cestode Dipylidium caninum. These free-ranging animals act as definitive hosts of 5 species known to have zoonotic potential; their presence in the area may generate a public and animal health problem if programs of dog and cat population control are not continued.

A molecular survey of zoonotic pathogens of public health importance in rodents/shrews and their ectoparasites trapped in Puducherry, India

BACKGROUND

Globally, India has a high zoonotic disease burden and lacks surveillance data in humans and animals. Rodents are known reservoirs for many zoonotic diseases and their synanthropic behavior poses a great public health threat.

METHODS

In this study, trapped rodents/shrews from randomly selected villages within Puducherry, India, and their ectoparasites were screened for zoonotic pathogens, namely, Orientia tsutsugamushi, other pathogenic rickettsiae, Leptospira spp., Cryptosporidium spp., Coxiella burnetii and methicillin-resistant Staphylococcus aureus (MRSA) using conventional PCR. A total of 58 rodents/shrews were trapped from 11 villages. The species trapped were Suncus murinus (49/58, 84.48%), Rattus rattus (8/58, 13.79%) and Rattus norvegicus (1/58, 1.72%). All ectoparasites collected were identified as mites and its infestation rate was 46.55% (27/58).

RESULTS

Real-time PCR targeting the 47 kDa gene of O. tsutsugamushi revealed positivity in one rodent and one shrew (3.45%) and two mite pools (7.41%). Conventional PCR targeting the 56 kDa gene revealed positivity in one shrew and two mite pools and the phylogenetic analysis of all three amplicons indicated the circulation of the Gilliam-related serotype. MRSA was detected in the alimentary tract of a shrew (1/32, 3.13%). Leptospira spp., Rickettsia, Cryptosporidium spp. and Co. burnetii tested negative.

CONCLUSIONS

The detection of zoonotic pathogens within reservoir hosts and vectors poses a risk of transmission to humans. This study signifies the need for zoonotic pathogen surveillance in synanthropic rodents/shrews.

Utilization and associated determinants of multi-sectoral approach in zoonotic disease surveillance among animal and human healthcare workers in Nakuru County, Kenya

Background

Zoonoses are naturally transmissible between humans and animals. Globally, they account for more than 60% of human infections, 75% of emerging infections, 2.7 million human deaths, and 10% of the total DALYs lost yearly in Africa. In the last three decades, Kenya has had sporadic outbreaks of zoonoses. To increase the speed of reporting and efficiencies in detection and control, a multi-sectoral collaboration in zoonotic disease surveillance (MZDS) between human and animal health workers is essential. In an effort, Zoonotic disease unit (ZDU) in Kenya has been established at national and county levels.

Methods

A cross sectional study was carried out to determine the level of utilization of multisectoral collaboration and its associated determinants in zoonotic disease surveillance among animal and human healthcare workers in Nakuru County. Quantitative data was gathered from 102 participants and qualitative data from 5 key informants. To test for significant differences, Chi-square and independent t-test were used.

Results

MZDS utilization level was 16% and the factors associated with MZDS utilization include; knowing what MZDS entails, education level, sector affiliation, trainings, supportive infrastructure, budget allocation and data storage. Lack of financing and poor coordination are hindrances to MZDS.

Conclusion

There is need to finance MZDS activities, strengthen coordination mechanisms, carry out more sensitization and trainings among animal and human healthcare workers.

A Generalizable Prioritization Protocol for Climate-Sensitive Zoonotic Diseases

Emerging and re-emerging zoonotic diseases pose a significant threat to global health and economic security. This threat is further aggravated by amplifying drivers of change, including climate hazards and landscape alterations induced by climate change. Given the complex relationships between climate change and zoonotic disease health outcomes, a structured decision-making process is required to effectively identify pathogens of greatest concern to prioritize prevention and surveillance efforts. Here, we describe a workshop-based expert elicitation process in six steps to prioritize climate-sensitive zoonoses based on a structured approach to defining criteria for climate sensitivity. Fuzzy analytical hierarchy process methodology is used to analyze data provided by experts across human, animal, and environmental health sectors accounting for uncertainties at different stages of the prioritization process. We also present a new interactive expert elicitation interface that facilitates data collection and real-time visualization of prioritization results. The novel approach presented in this paper offers a generalized platform for prioritizing climate-sensitive zoonoses at a national or regional level. This allows for a structured decision-making support process when allocating limited financial and personnel resources to enhance preparedness and response to zoonotic diseases amplified by climate change.

A review on camelid nanobodies with potential application in veterinary medicine

The single variable domains of camelid heavy-chain only antibodies, known as nanobodies, have taken a long journey since their discovery in 1989 until the first nanobody-based drug's entrance to the market in 2022. On account of their unique properties, nanobodies have been successfully used for diagnosis and therapy against various diseases or conditions. Although research on the application of recombinant antibodies has focused on human medicine, the development of nanobodies has paved the way for incorporating recombinant antibody production in favour of veterinary medicine. Currently, despite many efforts in developing these biomolecules with diversified applications, significant opportunities exist for exploiting these highly versatile and cost-effective antibodies in veterinary medicine. The present study attempts to identify existing gaps and shed light on paths for future research by presenting an updated review on camelid nanobodies with potential applications in veterinary medicine.

Impact of deforestation and climate on spatio-temporal spread of dengue fever in Mexico

Dengue prevalence results from the interaction of multiple socio-environmental variables which influence its spread. This study investigates the impact of forest loss, precipitation, and temperature on dengue incidence in Mexico from 2010 to 2020 using a Bayesian hierarchical spatial model. Three temporal structures-AR1, RW1, and RW2-were compared, with RW2 showing superior performance. Findings indicate that a 1 % loss of municipal forest cover correlates with a 16.9 % increase in dengue risk. Temperature also significantly affects the vectors' ability to initiate and maintain outbreaks, highlighting the significant role of environmental factors. The research emphasizes the importance of multilevel modeling, finer temporal data resolution, and understanding deforestation causes to enhance the predictability and effectiveness of public health interventions. As dengue continues affecting global populations, particularly in tropical and subtropical regions, this study contributes insights, advocating for an integrated approach to health and environmental policy to mitigate the impact of vector-borne diseases.

Integrative genomics would strengthen AMR understanding through ONE health approach

Emergence of drug-induced antimicrobial resistance (AMR) forms a crippling health and economic crisis worldwide, causing high mortality from otherwise treatable diseases and infections. Next Generation Sequencing (NGS) has significantly augmented detection of culture independent microbes, potential AMR in pathogens and elucidation of mechanisms underlying it. Here, we review recent findings of AMR evolution in pathogens aided by integrated genomic investigation strategies inclusive of bacteria, virus, fungi and AMR alleles. While AMR monitoring is dominated by data from hospital-related infections, we review genomic surveillance of both biotic and abiotic components involved in global AMR emergence and persistence. Identification of pathogen-intrinsic as well as environmental and/or host factors through robust genomics/bioinformatics, along with monitoring of type and frequency of antibiotic usage will greatly facilitate prediction of regional and global patterns of AMR evolution. Genomics-enabled AMR prediction and surveillance will be crucial - in shaping health and economic policies within the One Health framework to combat this global concern.

Parallel multi-criteria decision analysis for sub-national prioritization of zoonoses and animal diseases in Africa: The case of Cameroon

The use of multi-criteria decision analysis (MCDA) for disease prioritization at the sub-national level in sub-Sahara Africa (SSA) is rare. In this research, we contextualized MCDA for parallel prioritization of endemic zoonoses and animal diseases in The Adamawa and North regions of Cameroon. MCDA was associated to categorical principal component analysis (CATPCA), and two-step cluster analysis. Six and seven domains made of 17 and 19 criteria (out of 70) respectively were selected by CATPCA for the prioritization of zoonoses and animal diseases, respectively. The most influencing domains were "public health" for zoonoses and "control and prevention" for animal diseases. Twenty-seven zoonoses and 40 animal diseases were ranked and grouped in three clusters. Sensitivity analysis resulted in high correlation between complete models and reduced models showing the robustness of the simplification processes. The tool used in this study can be applied to prioritize endemic zoonoses and transboundary animal diseases in SSA at the sub-national level and upscaled at the national and regional levels. The relevance of MCDA is high because of its contextualization process and participatory nature enabling better operationalization of disease prioritization outcomes in the context of African countries or other low and middle-income countries.

Towards the development of cost-effective point-of-care diagnostic tools for poverty-related infectious diseases in sub-Saharan Africa

In this review, we examine the current landscape of point-of-care testing (POCT) diagnostic tools designed for poverty-related infectious diseases (PRIDs) in sub-Saharan Africa (sSA) while delineating key avenues for future advancements. Our analysis encompasses both established and emerging diagnostic methods for PRIDs, addressing the persistent challenges in POCT tool development and deployment, such as cost, accessibility, and reliability. We emphasize recent advancements in POCT diagnostic tools as well as platforms poised to enhance diagnostic testing in sSA. Recognizing the urgency for affordable and widely accessible POCT diagnostic tools to detect PRIDs in sSA, we advocate for a multidisciplinary approach. This approach integrates current and emerging diagnostic methods, explicitly addressing challenges hindering point-of-care (POC) tool development. Furthermore, it recognizes the profound impact of misdiagnosis on public and global health, emphasizing the need for effective tools. To facilitate the successful development and implementation of POCT diagnostic tools in sSA, we propose strategies including the creation of multi-analyte detection POCT tools, the implementation of education and training programs, community engagement initiatives, fostering public-private collaborations, and the establishment of reliable supply chains. Through these concerted efforts, we aim to accelerate the development of POCT in the sSA region, ensuring its effectiveness and accessibility in addressing the diagnostic challenges associated with PRIDs.

Beyond polio: Exploring non-polio enteroviruses, global health preparedness, and the "Disease X" paradigm

Background and Aims

Disease X represents the possibility that an unidentified infection may spread globally and start a pandemic. This study explored various aspects of emerging non-polio enteroviruses (NPEVs) as a possible source of "Disease X," an enigmatic agent declared by the World Health Organization, and discussed the potential impact of NPEVs on global public health.

Methods

In this perspective article, we collected information from publicly available sources such as Google Scholar, PubMed, and Scopus. We used NPEVs, viral diseases, pandemics, and zoonotic diseases as keywords. We extracted information from the most relevant articles.

Results

Notable outbreaks caused by NPEVs include enterovirus D68 (EV-D68) and enterovirus A71 (EV-A71), among many others. With a focus on therapeutic and preventative components, alternate modes of therapy, and the development of broad-spectrum antivirals, this analysis looks at the origin, epidemiology, genetic alterations, transmission dynamics, and disease pathophysiology of NPEVs. The information presented in the review indicates the current risk assessment of NPEVs, taking into account the following factors: the need for research and therapeutic interventions, the diversity of clinical manifestations, the impact of genetic variability on virulence, the persistence of emergence despite vaccination efforts, recurrent outbreaks, and the global impact of these viruses.

Conclusion

There is a possibility that NPEVs could trigger global pandemics based on their zoonotic origins and urges for complete readiness, continuous research, cooperation, and a comprehensive strategy to combat emerging infectious diseases in a constantly changing global environment. It is peak time to acknowledge how important it is to abide by safety and health laws to prevent these illnesses.

The application of the One Health approach in the management of five major zoonotic diseases using the World Bank domains: A scoping review

The international authorities, such as the Food and Agriculture Organization of the United Nations, World Health Organization, World Organization for Animal Health, United Nations Environment Programme, and World Bank, have endorsed the One Health concept as an effective approach to optimize the health of people, animals, and the environment. The One Health concept is considered as an integrated and unifying approach with the objective of sustainably balancing and optimizing the health of people, animals, and ecosystems. Despite variations in its definitions, the underlying principle remains consistent - recognizing the interconnected and interdependent health of humans, animals, and the environment, necessitating interdisciplinary collaboration to optimize health outcomes. The One Health approach has been applied in numerous countries for detecting, managing, and controlling diseases. Moreover, the concept has found application in various areas, including antimicrobial resistance, food safety, and ecotoxicology, with a growing demand. There is a growing consensus that the One Health concept and the United Nations Sustainable Development Goals mutually reinforce each other. The World Bank has recommended five domains as foundational building blocks for operationalising the One Health approach, which includes: i) One Health stakeholders, roles, and responsibilities; ii) financial and personal resources; iii) communication and information; iv) technical infrastructure; and v) governance. The domains provide a generalised overview of the One Health concept and guide to its application. We conducted a scoping review following the five-staged Arksey and O'Malley's framework. The objective of the review was to map and synthesise available evidence of application of the One Health approach to five major zoonotic diseases using the World Bank domains. Publications from the year 2004, marking the inception of the term 'One Health,' to 2022 were included. Information was charted and categorised against the World Bank domains identified as a priori. We included 1132 records obtained from three databases: Embase, Medline, and Global Health; as well as other sources. After excluding duplicates, screening for titles and abstracts, and full text screening, 20 articles that contained descriptions of 29 studies that implemented the One Health approach were selected for the review. We found that included studies varied in the extent to which the five domains were utilised. Less than half the total studies (45%) used all the five domains and none of the studies used all the sub-domains. The environmental sector showed an underrepresentation in the application of the One Health approach to zoonotic diseases as 14 (48%) studies in 10 articles did not mention it as a stakeholder. Sixty two percent of the studies mentioned receiving support from international partners in implementing the One Health approach and 76% of the studies were supported by international donors to conduct the studies. The review identified disparate funding mechanisms employed in the implementation of the One Health approach. However, there were limited discussions on plans for continuity and viability of these funding mechanisms in the future.

Global One Health index for zoonoses: A performance assessment in 160 countries and territories

The One Health (OH) approach is used to control/prevent zoonotic events. However, there is a lack of tools for systematically assessing OH practices. Here, we applied the Global OH Index (GOHI) to evaluate the global OH performance for zoonoses (GOHI-Zoonoses). The fuzzy analytic hierarchy process algorithm and fuzzy comparison matrix were used to calculate the weights and scores of five key indicators, 16 subindicators, and 31 datasets for 160 countries and territories worldwide. The distribution of GOHI-Zoonoses scores varies significantly across countries and regions, reflecting the strengths and weaknesses in controlling or responding to zoonotic threats. Correlation analyses revealed that the GOHI-Zoonoses score was associated with economic, sociodemographic, environmental, climatic, and zoological factors. Additionally, the Human Development Index had a positive effect on the score. This study provides an evidence-based reference and guidance for global, regional, and country-level efforts to optimize the health of people, animals, and the environment.

Knowledge, Attitude, and Prevention Practices towards Common Zoonotic Diseases in and around Bahir Dar City, North Western Ethiopia

The problem of zoonoses diseases is a global public and veterinary health concern. Globally coordinated and well-established research efforts are essential to successfully fighting and reducing the health burden of zoonoses. In our study area, the interplay of intense livestock animals, agricultural activities, and poor health services characterized the high risks of zoonotic diseases. Thus, people suffer from easily preventable diseases with hygiene and good-quality food. The main objectives of this study were to: (i) evaluate the knowledge, attitude, and prevention practices of people handling farm animals and their products toward common zoonotic diseases; and (ii) estimate the associated risk factors influencing their knowledge, attitude, and prevention practices. A questionnaire-based cross-sectional study was conducted from December 2021 to August 2022. A simple random sampling technique was followed to select respondents. Multivariable logistic regression model analysis was conducted using STATA version 14. The overall level of knowledge, attitude, and prevention practice for the major zoonotic disease was 52.5%, 68.6%, and 39.4%, respectively. Rabies, tuberculosis, taeniasis, anthrax, and brucellosis were the major zoonotic diseases selected by respondents in the study areas. The age of respondents, training status, educational status, and farm location were significantly (P  < 0.05) associated with the level of knowledge and prevention practice against zoonotic diseases. This study revealed that the level of knowledge, attitude, and prevention practices for major zoonotic diseases in Bahir Dar City were relatively poor. Therefore, a concerted effort among various government and nongovernment stakeholders, including veterinarians, public health officials, and environmental experts, is needed to create and raise awareness among livestock producers about the transmission and control methods and the economic and public health importance of zoonotic diseases.

Knowledge, perceptions, and practices around zoonotic diseases among actors in the livestock trade in the Lake Victoria crescent ecosystem in East Africa

Background

Zoonotic diseases such as anthrax, rabies, brucellosis, and Rift Valley fever pose a direct threat to health and undercut livelihoods in the communities in which they occur. A combination of anthropogenic and animal activities like migration and interaction with wildlife and their respective parasites and vectors drives the emergence and re-emergence of zoonotic diseases. Consequently, One Health interdisciplinary approaches that incorporate social scientists can provide key insights into complex local perceptions. The approach calls for collaboration between the human and animal health sectors, including the sharing of disease surveillance data necessary to alleviate disease impacts. Livestock traders interact closely with livestock, which puts them at elevated risk of infection and creates conditions by which they may spread zoonotic disease. It is thus essential to examine practices among actors involved in the livestock trade to understand the most appropriate ways to mitigate these risks.

Methods

A qualitative study was conducted among the actors in the livestock trade in Busia County on their knowledge and perceptions of zoonotic diseases and practices that may contribute to the spread, control, and prevention of zoonotic disease transmission. A thematic analysis framework was used to categorize and synthesize data from in-depth interviews (IDIs), key informant interviews (KIIs), and structured observations.

Results

Whereas participants could list livestock diseases, they could not identify which ones were zoonoses, demonstrating insufficient knowledge of zoonosis. They identify sick animals by checking for dropped ears, excess mucus production, diarrhea, bloody urinal discharge, and general animal activity levels. To prevent the spread of these diseases, they wash their animals, isolate sick animals from the rest of the stock, and vaccinate their animals. They seek help from animal health professionals for sick animals as part of curative practices. This shows that they perceive the diseases as serious and that they need to be attended to by professionals. The results also show that they perceive animals from outside the region to be more vulnerable to diseases compared to those from within. The actors in the livestock trade engage in practices like skinning dead animals before burying them; to them, this is a normal practice. Some also consume dead carcasses. These increase the risk of zoonotic disease transmission.

Conclusion

The actors involved in the livestock trade are critical in the prevention and elimination of zoonotic diseases; hence, they need to be involved when developing intervention programs and policies for animal health extension services. Training them as a continuum of animal health workers blends lay and professional knowledge, which, alongside their intense contact with large numbers of animals, becomes a critical disease surveillance tool. Increasing awareness of zoonoses by using multi-disciplinary teams with social scientists is urgently needed so that practices like skinning dead animals before disposing of them and consumption of dead carcasses can be minimized.

Poxviruses from the Concept of One Health

In the last 4 years, the world has experienced two pandemics of bat-borne viruses. Firstly, in 2019 the SARS-CoV-2 pandemic started and has been causing millions of deaths around the world. In 2022, a Monkeypox pandemic rose in various countries of the world. Those pandemics have witnessed movements and initiatives from healthcare and research institutions to establish a worldwide understanding to battle any future pandemics and biological threats. One Health concept is a modern, comprehensive, unifying ways to improve humans, animals, and ecosystems' health. This concept shows how much they are intertwined and related to one another, whether it is an environmental, or a pathological relation. This review aims to describe Poxviridae and its impact on the One Health concept, by studying the underlying causes of how poxviruses can affect the health of animals, humans, and environments. Reviewing the effect of disease transmission between animal to human, human to human, and animal to animal with pox viruses as a third party to achieve a total understanding of infection and viral transmission. Thus, contributing to enhance detection, diagnosis, research, and treatments regarding the application of One Health.

Exploring Disease Management and Control through Pathogen Diagnostics and One Health Initiative: A Concise Review

The "One Health" initiative is a critical strategy that recognizes the interconnectedness between human, animal, and environmental health in the spread and containment of infectious pathogens. With the ease of global transportation, transboundary disease outbreaks pose a significant threat to food safety and security, endangering public health and having a negative economic impact. Traditional diagnostic techniques based on genotypic and phenotypic analyses are expensive, time-consuming, and cannot be translated into point-of-care tools, hindering effective disease management and control. However, with advancements in molecular methods, biosensors, and new generation sequencing, rapid and reliable diagnostics are now available. This review provides a comprehensive insight into emergent viral and bacterial pathogens and antimicrobial resistance, highlighting the importance of "One Health" in connecting detection and effective treatment. By emphasizing the symbiotic relationship between human and animal health, this paper underscores the critical role of "One Health" initiatives in preventing and controlling infectious diseases.

Public awareness of One Health in China

One Health is recognized as an increasingly important approach to global health. It has the potential to inform interventions and governance approaches to prevent future pandemics. Successfully implementing the One Health approach in policy will require active engagement from the public, which begs the question: how aware is the public of One Health? In this study, we examine the level and distribution of One Health awareness among the general public in China using a survey conducted in Beijing (n = 1820). We distinguish between awareness of the term of "One Health" versus awareness of the core set of ideas - the interconnection between the health of people, animals, and the environment. Our analysis shows that 40% of respondents reported that they have heard of the term, but more than double the number indicated that they recognize the core idea of interconnection between people, animals, and the environment. Specifically, about 83% of the respondents said that they believe people's health is closely connected to animal health and 86% believe people's health is closely connected to plant and environmental health. Multiple regression analysis indicates that women, younger people, and individuals with a higher level of education show higher levels of One Health awareness than their counterparts. Being aware of the term is associated with higher recognition of the core ideas. Policymakers and health practitioners should consider these findings when designing public awareness campaigns and educational initiatives to promote One Health principles.

Zoonoses research in Somalia: A scoping review using a One Health approach

Zoonoses are likely to cause a substantial burden on both human and animal health systems in Somalia, given the close proximity between the pastoralist majority and their livestock. However, decades of instability leading to weak disease surveillance have meant that data on the burden of zoonoses is lacking. The aim of this scoping review was to assess and synthesize the available literature on the presence and burden of zoonoses in Somalia. We used keywords to search Web of Science for relevant publications. Studies were included if they contained relevant data on a zoonosis and were undertaken in Somalia or were undertaken in another country where exposure could reasonably be assumed to have occurred in Somalia (e.g., migrants/refugees, returning soldiers, exported animals). Studies were not included if they focused on Somali ethnic communities permanently living elsewhere or if zoonotic aspects were not considered. We extracted data on disease(s) reported, geographic focus, data reported (human, animal, environment), study design and author affiliation. A total of 22 zoonotic infections were documented in 76 publications. The most frequently studied diseases were Rift Valley Fever (n = 15, 17%), brucellosis (n = 13, 14%) and hepatitis E (n = 10, 11%). Around 30% of papers reported data from relevant populations outside Somalia. Only 18 papers undertook laboratory analysis within Somalia. Most papers reported data on humans (45%) and animals (36%) with limited research on the environmental domain. Descriptive studies (47%) dominated and most were led by non-Somali researchers (89% in first authors and 95% of last authors). This study highlights the need for well-designed zoonoses research in Somalia supported by capacity building of local researchers and investments in diagnostic laboratories.

Assessing the Knowledge and Awareness Among Selected Tertiary Students in the Accra Metropolis on Zoonotic Infections

Background

Zoonotic infections are a serious threat to human health and a direct risk that could potentially be fatal. Animals both domestic and wild serve as reservoirs for zoonotic infections. Thus, frequent contact with animals might occasionally result in the transfer of infections from animals to people. Ghana is especially susceptible to the effects of zoonotic infections due to the increase in the household human-animal ratio. This study assessed the awareness and knowledge level of tertiary students in a selected tertiary institution on zoonotic infections.

Methods

A quantitative research method was employed making use of a descriptive cross-sectional study design. The target population chosen for the research was mainly students from the University of Ghana. A stratified sampling technique was used in selecting participants for the study. 440 participants were selected for the study. The university's four primary colleges served as the strata for the basis of data collection.

Results

The study revealed a moderate knowledge level among students. The term "zoonoses" was understood by the majority (70%) of the respondents. Respondents knew at least one route of transmission of zoonotic infection. For the spread of zoonotic infections, close contact with infected animals and consumption of contaminated food were seen as ways of spread by a majority.

Conclusion

Although the basic strategies required for the control and elimination of the zoonotic diseases in such tertiary institutions are well known and practiced as per the study findings, zoonoses still persists and this can be attributed to low education on the subject. Knowledge and awareness level on zoonoses especially in tertiary institutions such as the University of Ghana could be improved if relevant authorities create adequate enlightenment programs on improving the knowledge of zoonotic diseases through a variety of media including seminars, workshop, television, radio, newspaper and social media.

Stakeholder opinion-led study to identify canine priority diseases for surveillance and control in the UK

BACKGROUND

Many pathogens cause disease in dogs; however, meaningful surveillance in small companion animals is often only possible for the most impactful diseases. We describe the first stakeholder opinion-led approach to identify which canine infectious diseases should be prioritised for inclusion in surveillance and control strategies in the UK.

METHODS

Participants were identified through a stakeholder analysis. A multicriteria decision analysis was undertaken to establish and weight epidemiological criteria for evaluating diseases, and a Delphi technique was employed to achieve a consensus among participants on the top-priority canine diseases.

RESULTS

Nineteen stakeholders from multiple backgrounds participated in this study. Leptospirosis and parvovirus were identified as the top two endemic diseases of concern, while leishmaniosis and babesiosis were the top two exotic diseases. Respiratory and gastrointestinal diseases were identified as the top two syndromes of concern.

LIMITATIONS

Due to the COVID-19 pandemic, the number of participants was reduced. Despite this, a representative multidisciplinary sample of relevant stakeholders contributed to the present study.

CONCLUSIONS

Findings from this study are being used to inform the development of a future UK-wide epidemic response strategy. This methodology could provide a blueprint for other countries.

Surveillance and response strategies for zoonotic diseases: a comprehensive review

Out of all emerging infectious diseases, approximately 75% are of zoonotic origin, with their source often traced back to animals. The emergence of zoonoses is driven by a complex interplay between anthropogenic, genetic, ecological, socioeconomic, and climatic factors. This intricate web of influences poses significant challenges for the prediction and prevention of zoonotic outbreaks. Effective coordination and collaboration among the animal, human, and environmental health sectors are essential for proactively addressing major zoonotic diseases. Despite advancements in surveillance and diagnostic practices, the emergence of zoonoses continues to be a pressing global concern. Therefore, prioritizing zoonotic disease surveillance is of paramount importance as part of a comprehensive disease prevention and containment strategy. Furthermore, evaluating existing surveillance systems provides insights into the challenges faced, which can be mitigated through implementation of One Health principles involving relevant stakeholders. To initiate multisectoral partnerships, it is crucial to identify the priorities and core themes of surveillance systems with equitable inputs from various sectors. Strengthening surveillance, promoting data sharing, enhancing laboratory testing capabilities, and fostering joint outbreak responses in both the human and animal health sectors will establish the necessary infrastructure to effectively prevent, predict, detect, and respond to emerging health threats, thereby reinforcing global health security. This review assesses existing surveillance approaches by offering an overview of global agencies engaged in monitoring zoonoses and outlines the essential components required at the human-animal-environment interface for designing comprehensive surveillance networks. Additionally, it discusses the key steps necessary for executing effective zoonotic disease surveillance through a One Health approach, while highlighting the key challenges encountered in establishing such a robust surveillance system.

Data analysis of zoonoses notifications in Aboriginal and Torres Strait Islander populations in Australia 1996-2021: implications for One Health

Introduction

Zoonoses are a health concern for Aboriginal and Torres Strait Islander peoples in Australia that face elevated risk of disease related to the environment and animals. Internationally, One Health is encouraged to effectively manage zoonoses by taking integrated approaches involving animal, human, and environmental health sectors to improve health outcomes. However, Australia's health systems manage zoonotic diseases in animals and people separately which does not support a One Health approach. For the effective management of zoonoses, a strong evidence base and database regarding the epidemiology of zoonotic pathogens is needed. However, we currently lack this evidence limiting our understanding of the impact of zoonoses on Aboriginal and Torres Strait Islander populations.

Methods

As a first step towards building the evidence base, we undertook a descriptive analysis of Aboriginal and Torres Strait Islander zoonotic notifications in Australia from 1996 to 2021. We presented notifications as annual notification rates per 100,000 population, and percentages of notifications by state, remoteness, sex, and age group.

Results

Salmonellosis and campylobacteriosis were the most notified zoonoses with the highest annual notification rates of 99.75 and 87.46 per 100,000 population, respectively. The north of Australia (Queensland, Northern Territory and Western Australia), remote and outer regional areas, and young children (0-4 years of age) had the highest percentages of notifications.

Discussion

To our knowledge, these findings are the first national presentation of the epidemiology of zoonoses within Aboriginal and Torres Strait Islander populations. A greater understanding of transmission, prevalence and impact of zoonoses on Aboriginal and Torres Strait Islander peoples (including animal and environmental health factors) is required to inform their effective management through a One Health approach.

Global prioritization of endemic zoonotic diseases for conducting surveillance in domestic animals to protect public health

Zoonotic diseases (zoonoses) originating from domestic animals pose a significant risk to people's health and livelihoods, in addition to jeopardizing animal health and production. Effective surveillance of endemic zoonoses at the animal level is crucial to assessing the disease burden and risk, and providing early warning to prevent epidemics in animals and spillover to humans. Here we aimed to prioritize and characterize zoonoses for which surveillance in domestic animals is important to prevent human infections at a global scale. A multi-criteria qualitative approach was used, where disease-specific information was obtained across literature of the leading international health organizations. Thirty-two zoonoses were prioritized, all of which have multi-regional spread, cause unexceptional human infections and have domestic animal hosts as important sources or sentinels of zoonotic infections. Most diseases involve multiple animal hosts and/or modes of zoonotic transmission, where a lack of specific clinical signs in animals further complicates surveillance. We discuss the challenges of animal health surveillance in endemic and resource-limited settings, as well as potential avenues for improvement such as the multi-disease, multi-sectoral and digital surveillance approaches. Our study will support global capacity-building efforts to strengthen the surveillance and control of endemic zoonoses at their animal sources. This article is part of the theme issue 'Challenges and opportunities in the fight against neglected tropical diseases: a decade from the London Declaration on NTDs'.

One Health Surveillance System in Gujarat, India: A Health Policy and Systems Research Protocol for Exploring the Cross-Sectoral Collaborations to Detect Emerging Threats at the Human-Animal-Environment Interface

The close interaction between humans, animals and the ecosystem has been a reason for the emergence and re-emergence of zoonotic diseases worldwide. Zoonoses are estimated to be responsible for 2.5 billion human illnesses and 2.7 million deaths worldwide. Gujarat is a western state in India with more than 65 million people and 26 million livestock, and includes surveillance systems for humans and animals; however, more evidence is needed on joint collaborative activities and their effect on the early warning response for zoonoses. Thus, this study aims to investigate sectoral collaborations for early warning and response systems for emerging and re-emerging zoonoses, aiming to develop a One Health surveillance (OHS) system in Gujarat, India. This case study uses policy content analysis followed by qualitative and quantitative data collection among state- and district-level surveillance actors to provide insight into the current cross-sectoral collaborations among surveillance actors. It helps identify triggers and documents factors helpful in strengthening cross-sectoral collaborations among these systems and facilitates the establishment of an OHS system in Gujarat, India.

Zoonoses and emerging pathogens

Zoonoses represent a major challenge for many disciplines, including microbiology, epidemiology, veterinary, medicine and ecology. Moreover, they pose severe risks to human health and economy. In this editorial, we invite contributions to a BMC Microbiology collection on 'Zoonoses and emerging pathogens', covering research on the pathogenesis, identification, treatment and control of zoonoses.

Characterization, Directed Evolution, and Targeting of DNA Virus-Encoded RNA Capping Enzymes Using Phenotypic Yeast Platforms

The constant and the sudden emergence of zoonotic human and animal viruses is a significant threat to human health, the world economy, and the world food supply. This has necessitated the development of broad-spectrum therapeutic strategies to combat these emerging pathogens. Mechanisms that are essential for viral replication and propagation have been successfully targeted in the past to develop broad-spectrum therapeutics that can be readily repurposed to combat new zoonotic pathogens. Because of the importance of viral RNA capping enzymes to viral replication and pathogenesis, as well as their presence in both DNA and RNA viruses, these viral proteins have been a long-standing therapeutic target. Here, we use genome sequencing information and yeast-based platforms (YeRC0M) to identify, characterize, and target viral genome-encoded essential RNA capping enzymes from emerging strains of DNA viruses, i.e., Monkeypox virus and African Swine Fever Virus, which are a significant threat to human and domestic animal health. We first identified and biochemically characterized these viral RNA capping enzymes and their necessary protein domains. We observed significant differences in functional protein domains and organization for RNA capping enzymes from emerging DNA viruses in comparison to emerging RNA viruses. We also observed several differences in the biochemical properties of these viral RNA capping enzymes using our phenotypic yeast-based approaches (YeRC0M) as compared to the previous in vitro studies. Further, using directed evolution, we were able to identify inactivation and attenuation mutations in these essential viral RNA capping enzymes; these data could have implications on virus biocontainment as well as live attenuated vaccine development. We also developed methods that would facilitate high-throughput phenotypic screening to identify broad-spectrum inhibitors that selectively target viral RNA capping enzymes over host RNA capping enzymes. As demonstrated here, our approaches to identify, characterize, and target viral genome-encoded essential RNA capping enzymes are highly modular and can be readily adapted for targeting emerging viral pathogens as well as their variants that emerge in the future.

Neglected zoonotic helminthiases in wild canids: new insights from South America

The global threat of neglected tropical diseases (NTDs) constitutes a public health issue in underdeveloped countries. Zoonotic helminthiases are the most common human NTD agents in developing countries in sub-Saharan Africa, Asia, and the Americas, causing a global burden of disease that exceeds that of more recognized infectious diseases such as malaria and tuberculosis. Wild canids are well-known mammals that act as natural reservoirs of zoonotic-relevant helminthiasis worldwide, thus playing a pivotal role in their epidemiology and transmission to humans. Here we evaluate the occurrence of zoonotic gastrointestinal helminths in two Neotropical wild canid species from the Amazonian and Andean regions of Colombia, i.e., the bush dog (Speothos venaticus) and the crab-eating fox (Cerdocyon thous). We recovered tapeworm proglottids from bush dog fecal samples and identified them molecularly as the canine-specific lineage of Dipylidium caninum by using cytochrome c oxidase subunit I (cox1) gene sequences. Moreover, examination of a crab-eating fox during necropsy revealed the presence of non-embryonated eggs of the neglected nematode Lagochilascaris cf. minor, in addition to eggs and gravid proglottids of the cestode Spirometra mansoni. These findings represent the first report of zoonotic-relevant cestodes, i.e., D. caninum ("canine genotype"), S. mansoni, and the nematode L. cf. minor, in bush dogs and crab-eating foxes as final hosts. The occurrence of these zoonotic helminthiases in wild canid species calls for regular monitoring programs to better understand the epidemiology and transmission routes of neglected dipylidiasis, lagochilascariosis, and sparganosis in South America.

A scoping review of zoonotic parasites and pathogens associated with abattoirs in Eastern Africa and recommendations for abattoirs as disease surveillance sites

Abattoirs are facilities where livestock are slaughtered and are an important aspect in the food production chain. There are several types of abattoirs, which differ in infrastructure and facilities, sanitation and PPE practices, and adherence to regulations. In each abattoir facility, worker exposure to animals and animal products increases their risk of infection from zoonotic pathogens. Backyard abattoirs and slaughter slabs have the highest risk of pathogen transmission because of substandard hygiene practices and minimal infrastructure. These abattoir conditions can often contribute to environmental contamination and may play a significant role in disease outbreaks within communities. To assess further the risk of disease, we conducted a scoping review of parasites and pathogens among livestock and human workers in abattoirs across 13 Eastern African countries, which are hotspots for zoonoses. Our search results (n = 104 articles) showed the presence of bacteria, viruses, fungi, and macroparasites (nematodes, cestodes, etc.) in cattle, goats, sheep, pigs, camels, and poultry. Most articles reported results from cattle, and the most frequent pathogen detected was Mycobacterium bovis, which causes bovine tuberculosis. Some articles included worker survey and questionnaires that suggested how the use of PPE along with proper worker training and safe animal handling practices could reduce disease risk. Based on these findings, we discuss ways to improve abattoir biosafety and increase biosurveillance for disease control and mitigation. Abattoirs are a 'catch all' for pathogens, and by surveying animals at abattoirs, health officials can determine which diseases are prevalent in different regions and which pathogens are most likely transmitted from wildlife to livestock. We suggest a regional approach to biosurveillance, which will improve testing and data gathering for enhanced disease risk mapping and forecasting. Next generation sequencing will be key in identifying a wide range of pathogens, rather than a targeted approach.

Toward One Health: a spatial indicator system to model the facilitation of the spread of zoonotic diseases

Recurrent outbreaks of zoonotic infectious diseases highlight the importance of considering the interconnections between human, animal, and environmental health in disease prevention and control. This has given rise to the concept of One Health, which recognizes the interconnectedness of between human and animal health within their ecosystems. As a contribution to the One Health approach, this study aims to develop an indicator system to model the facilitation of the spread of zoonotic diseases. Initially, a literature review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement to identify relevant indicators related to One Health. The selected indicators focused on demographics, socioeconomic aspects, interactions between animal and human populations and water bodies, as well as environmental conditions related to air quality and climate. These indicators were characterized using values obtained from the literature or calculated through distance analysis, geoprocessing tasks, and other methods. Subsequently, Multi-Criteria Decision-Making (MCDM) techniques, specifically the Entropy and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) methods, were utilized to combine the indicators and create a composite metric for assessing the spread of zoonotic diseases. The final indicators selected were then tested against recorded zoonoses in the Valencian Community (Spain) for 2021, and a strong positive correlation was identified. Therefore, the proposed indicator system can be valuable in guiding the development of planning strategies that align with the One Health principles. Based on the results achieved, such strategies may prioritize the preservation of natural landscape features to mitigate habitat encroachment, protect land and water resources, and attenuate extreme atmospheric conditions.

Prevalence and occupational exposure to zoonotic diseases in high-risk populations in the Free State Province, South Africa

Introduction

Zoonotic diseases are responsible for 2.5 billion human cases globally and approximately 2.7 million deaths annually. Surveillance of animal handlers and livestock for zoonotic pathogens contributes to understanding the true disease burden and risk factors within a community. This study investigated the prevalence of selected zoonoses in cattle, farm workers and occupational exposure to endemic zoonotic diseases and their associated risk factors.

Methods

Sputum samples from farmworkers were screened for Mycobacterium bovis. Blood specimens from farmworkers and archived sera were tested for serological evidence of Brucella sp., hantaviruses, and Leptospira sp. Communal and commercial cattle herds were tested for bovine tuberculosis and brucellosis.

Results

Mycobacterium bovis was not isolated from human samples. A total of 327 human sera were screened, and 35/327 (10.7%) were Brucella sp. IgG positive, 17/327 (5.2%) Leptospira sp. IgM positive, and 38/327 (11.6%) hantavirus IgG positive (95% CI). A higher proportion of Brucella sp. IgG-positive samples were detected among veterinarians (value of p = 0.0006). Additionally, two cattle from a commercial dairy farm were bovine tuberculosis (bTB) positive using the bTB skin test and confirmatory interferon-gamma assay. A higher percentage of confirmed brucellosis-positive animals were from communal herds (8.7%) compared to commercial herds (1.1%).

Discussion

These findings highlight the brucellosis and M. bovis prevalence in commercial and communal herds, the zoonotic disease risk in commercial and subsistence farming in developing countries, and the occupational and rural exposure risk to zoonotic pathogens.

Public Knowledge, Attitudes, and Practices Regarding Brucellosis in Taif City, Saudi Arabia

BACKGROUND

Brucellosis is a serious zoonotic infectious disease. Humans contract the disease by coming into contact with infected animals or their products. In Saudi Arabia, brucellosis is considered to be an endemic disease, with an annual incidence of 15.34 per 100,000 population from 2003 to 2018. Because of the devastating consequences for human health, raising awareness is an essential component in preventing brucellosis. Our study aims to assess the knowledge, awareness, and attitudes regarding brucellosis among the residents of Taif City, Saudi Arabia.

METHODS

A descriptive, cross-sectional survey conducted in June-October 2022 targeted the population of Taif City, Saudi Arabia. The data were collected by an online questionnaire, which included questions on sociodemographic characteristics, awareness regarding brucellosis, behavior and attitude toward animals, and consuming animal-based products.

RESULTS

A total of 743 participants were included. The participants were 18-70 years old, 63.4% were females, and 79.4% had a university education. Only 450 participants answered yes to the first question: "Do you know about brucellosis or have you heard about it?" Therefore, they were asked to answer knowledge questions. It was found that out of 450 participants, 46.9% demonstrated a "poor" knowledge level. Participants aged 26-55 years old demonstrated significantly more "good" knowledge than the other age groups (p = 0.001). Males demonstrated significantly more "good" knowledge (30.6%) than females (14.9%) (p < 0.001). The practices and attitudes of animal breeder participants (16.2%) were satisfactory because more than half of them did not participate in the birth of animals (53.4%), 50.7% did not participate in the birth with abortion, and approximately 61% used gloves when taking care of animals. The practices were unsatisfactory because 53.4% of the participants reported that they "always" eat the meat of animals they keep, and 64.4% reported that they personally slaughter sheep or cows from the herd.

CONCLUSION

Our study showed that most of the participants were aware of brucellosis; however, at the same time, the knowledge level regarding brucellosis was not satisfactory.

The interfaces between One Health and Global Health: A scoping review

One Health (OH) and Global Health (GH) are interconnected perspectives that may contribute to subsidizing GH policies. This scoping review aims to map the volume, nature, and characteristics of studies focused on the interface of OH and GH concepts. We used PubMed (MEDLINE), Embase, Scopus, and The Virtual Health Library (BVS) as the literature data sources for the review. The search strategy used the descriptors "one health", "one health concept", "one medicine", "global health", "international health", and "planetary health" in title and abstracts. We included original research presented as articles in scientific journals, book chapters or conference papers written in English, Spanish, or Portuguese, exploring the intersections between OH and GH concepts, not necessarily as their primary objectives, and published up to December 31, 2021. A total of 1.060 references were identified in the databases after removing duplicates, 139 publications selected for full-text evaluation and 45 publications were included for analysis. All included publications were published between 2011 and 2021, with the highest concentration in 2014 (22.2%). First authors were most frequently from the United States (35.6%), followed by the United Kingdom (15.6%). Overall, seven key themes were identified zoonosis, emerging infectious diseases, antimicrobial resistance, food safety, policy, human resources, and Sustainable Development Goals (SDG). The majority of the included publications employed OH concepts based on the United States Centre for Disease Control and Prevention, and the American Veterinary Medical Association definitions. We observed a common understanding of OH as an area of knowledge involving multiple disciplines and professionals and recognizing that both humans' and animals' health and the environment are interdependent. Although most authors demonstrated that health issues transcend national boundaries, a formal definition for GH was frequently not clearly identified. OH and GH interfaces are essential for accomplishing the 2030 Agenda and its SDG.

Examining ecosystem (dis-)services on liver fluke infection in rural Northeast Thailand

BACKGROUND

The direct reliance of humans on and their interactions with freshwater ecosystems in the Lower Mekong Basin have given rise to parasitic infections, which is particularly prevalent in Northeast Thailand where raw fish consumption is practiced. This study examined the interactions between environments, ecosystem (dis-)services, human raw fish consumption habits, and raw fish dish sharing on liver fluke infection risk.

METHOD

Water fecal contents and the first intermediate snail host were sampled between June and September of 2019. One hundred twenty questionnaires were surveyed in two villages of different environmental surroundings, one next to a river and the other located inland, in Northeast Thailand. Multivariate regression analyses using linear mixed effect models assessed the influence of social, behavioral and perceptual factors on raw fish consumption frequency, willingness to avoid consumption and liver fluke infection status. Social network analysis compared the degree of raw fish dish sharing between the villages and assessed the probable influence of connections to fish procurement locations and sharing activities on liver fluke infection risk.

RESULTS

High abundance of the first intermediate snail host and presence of fecal contamination in water could endanger both villages to ecosystem disservices of parasitic transmission. The river-side village relied more on provisioning ecosystem services than the inland village (29.7% vs. 16.1% of villages) to consume raw fish as their main source of protein. Males in both villages (64.5 and 40.4 days/year for the respective villages) are also likely to consume koi pla and pla som, higher risk fish dishes, more frequently than females (4.1 and 4.3 days/year for the respective villages). The consumption habits of both villages were driven mostly by deriving cultural ecosystem services. Participation in raw fish dish sharing activities significantly reduced the odds of an individual being willing to avoid the consumption (Odds ratio = 0.19). Network analysis suggested that river-side villagers had a more direct raw fish dish sharing interaction and they procured fish from multiple locations; these characteristics might potentially account for more liver fluke infected households in the village.

CONCLUSION

Villagers' raw fish consumption is driven by deriving cultural ecosystem services, and the geographic settings of the villages potentially affect villagers' fish procurement locations and infection risk. The findings underscore the linkages between villagers and their surrounding ecosystem environments as pertinent determinants for foodborne parasitic disease risk.

Analysis of available animal testing data to propose peer-derived quantitative thresholds for determining adequate surveillance capacity for rabies

Historical targets for country-level animal rabies testing volumes were abandoned due to ethical and welfare concerns, and interpretation challenges of testing healthy animals. To-date, no quantitative threshold has been established for evaluating adequate surveillance capacity specific to suspected rabid animals. The purpose here is to establish quantitative testing thresholds for rabies suspected animals to assess a country's rabies surveillance capacity. Animal rabies testing data was obtained from official and unofficial rabies surveillance platforms from 2010 to 2019 and supplemented with official country reports and published literature. Testing rates were determined for all-animal and domestic animals, and standardized per 100,000 estimated human population; the domestic animal rate was also standardized per 100,000 estimated dog population. There were 113 countries that reported surveillance data eligible for analysis. Countries reporting the most data were under WHO categories as having endemic human rabies or no dog rabies. The annual median all-animal testing rate for all countries was 1.53 animals/100,000 human population (IQR 0.27-8.78). Three proposed testing rate thresholds are an all-animal rate of 1.9 animals/100,000 humans, a domestic animal per human rate of 0.8 animals/100,000 humans, and a domestic animal per dog rate of 6.6 animals/100,000 dogs. These three peer-derived rabies testing thresholds for passive surveillance can be used to facilitate assessment of a country's rabies surveillance capacity.

One health zoonotic disease prioritization and systems mapping: An integration of two One Health tools

One Health is a collaborative approach that requires synergies between human, animal and environmental health sectors, other key sectors, and partners supporting these capacity-building efforts. Multiple One Health capacity-building tools are available that can be used independently or together. Two tools that have been used in sequence to inform each other include the US Centers for Disease Control and Prevention's One Health Zoonotic Disease Prioritization (OHZDP) Process and University of Minnesota/US Department of Agriculture's One Health Systems Mapping and Analysis Resource Toolkit™ (OH-SMART). In August 2017, a workshop was held in Islamabad, Pakistan, that integrated these two tools for the first time. In this integrated workshop, we used the OHZDP to develop a list of priority zoonotic diseases for Pakistan and OH-SMART™ to conduct a partner assessment and disease-specific gap analysis. Both tools were used to identify areas for One Health collaboration for the priority zoonotic diseases. Additionally, we trained 11 in-country facilitators representing the human and animal health sectors on both tools. This manuscript describes the integration of these two tools-using the Pakistan workshop as a process case study-to inform future efforts to implement One Health tools synergistically. Implementation of the technical and logistical aspects of the integrated workshop was detailed: (1) workshop preparation, (2) facilitator training, (3) workshop implementation and (4) workshop outcomes. Sixteen months after the workshop, we conducted an in-country facilitator survey to follow-up on the utility of both tools and the training for facilitators. We evaluated facilitator survey results using a qualitative analysis software Atlas.ti. Using the OHZDP Process and OH-SMART™ together achieved continuity between the two processes and provided a professional development opportunity for in-country facilitators. Based on the success of this integrated workshop, partners developing and implementing One Health tools should recognize the importance of collaboration to maximize outcomes.

Multisectoral prioritization of zoonotic diseases in Haryana (India) using one health approach

Zoonotic diseases have huge livestock and public health burden worldwide, including India. Prioritizing zoonotic diseases is one of the important tasks under 'One Health' as it facilitates effective policy making, proper allocation of resources and promotion of multisectoral collaboration. Although some efforts have been made to prioritizing zoonotic diseases at national level in India, it is important to identify priority diseases in regional settings due to wide variation in climate and demography of different states. Therefore, the present study aims to prioritize zoonotic diseases for the state of Haryana (India). One Health Zoonotic Disease Prioritization (OHZDP) tool was used in this study to prioritize zoonotic diseases. Based on literature review of the past 23 years (2000-2022) on prevalence, morbidity, and mortality of zoonotic diseases, twenty-three high-scoring zoonotic diseases in Haryana and neighboring states of India were initially shortlisted for prioritization. A three-day participatory workshop was conducted involving 17 experts representing the Health, Animal Husbandry and Wildlife departments of Haryana. The Analytical Hierarchy Process (AHP) was used to rank the criteria, which were used to score the selected diseases using the decision tree analysis. The participants selected the following 7 criteria along with their relative weights to score the diseases: (1) Severity of disease in humans, (2) Severity of disease in animals, (3) Presence of disease in the region, (4) Transmission and outbreak potential, (5) Socio-economic impact, (6) Availability of interventions, and (7) Existing inter-sectoral collaboration for surveillance and reporting. The top scoring eight diseases selected as priority zoonotic diseases for Haryana were rabies, Japanese encephalitis, bovine tuberculosis, leptospirosis, avian influenza (H5N1), brucellosis, glanders and Influenza A (H1N1). Sensitivity analysis did not reveal any significant variation in prioritization results by varying criteria weights. This is the first systemic attempt to prioritize zoonotic diseases in the state and this will help in formulating effective monitoring, prevention, and control strategies for zoonotic diseases in the regional settings.

A global analysis of One Health Networks and the proliferation of One Health collaborations

There has been a renewed focus on threats to the human-animal-environment interface as a result of the COVID-19 pandemic, and investments in One Health collaborations are expected to increase. Efforts to monitor the development of One Health Networks (OHNs) are essential to avoid duplication or misalignment of investments. This Series paper shows the global distribution of existing OHNs and assesses their collective characteristics to identify potential deficits in the ways OHNs have formed and to help increase the effectiveness of investments. We searched PubMed, Google, Google Scholar, and relevant conference websites for potential OHNs and identified 184 worldwide for further analysis. We developed four case studies to show important findings from our research and exemplify best practices in One Health operationalisation. Our findings show that, although more OHNs were formed in the past 10 years than in the preceding decade, investment in OHNs has not been equitably distributed; more OHNs are formed and headquartered in Europe than in any other region, and emerging infections and novel pathogens were the priority focus area for most OHNs, with fewer OHNs focusing on other important hazards and pressing threats to health security. We found substantial deficits in the OHNs collaboration model regarding the diversity of stakeholder and sector representation, which we argue impedes effective and equitable OHN formation and contributes to other imbalances in OHN distribution and priorities. These findings are supported by previous evidence that shows the skewed investment in One Health thus far. The increased attention to One Health after the COVID-19 pandemic is an opportunity to focus efforts and resources to areas that need them most. Analyses, such as this Series paper, should be used to establish databases and repositories of OHNs worldwide. Increased attention should then be given to understanding existing resource allocation and distribution patterns, establish more egalitarian networks that encompass the breadth of One Health issues, and serve communities most affected by emerging, re-emerging, or endemic threats at the human-animal-environment interface.

SARS-CoV-2 Affects Both Humans and Animals: What Is the Potential Transmission Risk? A Literature Review

In March 2020, the World Health Organization Department declared the coronavirus (COVID-19) outbreak a global pandemic, as a consequence of its rapid spread on all continents. The COVID-19 pandemic has been not only a health emergency but also a serious general problem as fear of contagion and severe restrictions put economic and social activity on hold in many countries. Considering the close link between human and animal health, COVID-19 might infect wild and companion animals, and spawn dangerous viral mutants that could jump back and pose an ulterior threat to us. The purpose of this review is to provide an overview of the pandemic, with a particular focus on the clinical manifestations in humans and animals, the different diagnosis methods, the potential transmission risks, and their potential direct impact on the human-animal relationship.

Determinación de los principales parásitos intestinales en perros de Unidades Habitacionales y Parques en Apizaco, Tlaxcala, México

El vínculo entre perros y humanos es un fenómeno complejo y multidimensional, que, además de biológico es social y llega a ser un problema de Salud Pública. El concepto de dueño de una mascota ha evolucionado al término de tutor, por la relación de las personas con los perros, quienes además poseen derechos y están protegidos por leyes internacionales de protección animal. El objetivo del trabajo fue analizar el manejo de las heces y evaluar la presencia de helmintos en las Unidades Habitacionales y Parques (UHyPR) recreativos de Apizaco, Tlaxcala, México. Se empleó un estudio descriptivo transversal. El 75 % de las personas con perros recogen las heces en bolsas y las depositan en basureros. Hubo diferencias significativas (P<0,05) a presencia de parásitos, 66 % de perros con tutores y 89 % perros sin tutor. Los parásitos identificados fueron Toxocara canis, Ancylostoma caninum, Cystoisospora y Uncinaria stenocephala. Los perros sin tutor fueron los más parasitados 90 % (P<0,05), prevaleciendo T. canis (36 %) y A. caninum (56 %). Se encontró que los perros con tutor y acceso a vía pública presentaron T. canis (73 %) y A. caninum (77 %). Perros con tutor sin acceso a vía pública tuvieron: 49 % T. canis y 15 % A. caninum. Los perros sin dueño se asociaron (P=0,046) con mayor número de nemátodos intestinales. En conclusión, en las UHyPR en Apizaco, Tlaxcala se presenta un problema de manejo de excretas de perros, que al estar expuestas son causa de zoonosis por parásitos, lo que muestra la necesidad de un programa integral de salud pública hacia la tenencia responsable de mascotas, que abarque todos los sectores de la sociedad.

Two phase feature-ranking for new soil dataset for Coxiella burnetii persistence and classification using machine learning models

Coxiella burnetii (Cb) is a hardy, stealth bacterial pathogen lethal for humans and animals. Its tremendous resistance to the environment, ease of propagation, and incredibly low infectious dosage make it an attractive organism for biowarfare. Current research on the classification of Coxiella and features influencing its presence in the soil is generally confined to statistical techniques. Machine learning other than traditional approaches can help us better predict epidemiological modeling for this soil-based pathogen of public significance. We developed a two-phase feature-ranking technique for the pathogen on a new soil feature dataset. The feature ranking applies methods such as ReliefF (RLF), OneR (ONR), and correlation (CR) for the first phase and a combination of techniques utilizing weighted scores to determine the final soil attribute ranks in the second phase. Different classification methods such as Support Vector Machine (SVM), Linear Discriminant Analysis (LDA), Logistic Regression (LR), and Multi-Layer Perceptron (MLP) have been utilized for the classification of soil attribute dataset for Coxiella positive and negative soils. The feature-ranking methods established that potassium, chromium, cadmium, nitrogen, organic matter, and soluble salts are the most significant attributes. At the same time, manganese, clay, phosphorous, copper, and lead are the least contributing soil features for the prevalence of the bacteria. However, potassium is the most influential feature, and manganese is the least significant soil feature. The attribute ranking using RLF generates the most promising results among the ranking methods by generating an accuracy of 80.85% for MLP, 79.79% for LR, and 79.8% for LDA. Overall, SVM and MLP are the best-performing classifiers, where SVM yields an accuracy of 82.98% and 81.91% for attribute ranking by CR and RLF; and MLP generates an accuracy of 76.60% for ONR. Thus, machine models can help us better understand the environment, assisting in the prevalence of bacteria and decreasing the chances of false classification. Subsequently, this can assist in controlling epidemics and alleviating the devastating effect on the socio-economics of society.
