Knowledge, attitude and practices (KAP) towards Anthrax among livestock farmers in selected rural areas of Bangladesh

Assessment of knowledge, attitudes, and practices on vaccine usage among large ruminant farmers in the rangpur division of Bangladesh

BACKGROUNDS

Vaccines are crucial for preventing and controlling diseases in ruminant livestock. However, the effectiveness of vaccination campaigns depends on livestock producers' knowledge, perspectives, and behaviours towards their implementation. Unfortunately, as far as the author knowledge, no studies have been conducted in Bangladesh to assess the knowledge, attitudes, and practices (KAP) status of large ruminant farmers (LRF) regarding vaccine use against infectious diseases. Therefore, the aim of the present study was to address this research gap in Bangladesh for the first time.

METHODS

A cross-sectional study was conducted among 244 LRF in selected regions of Rangpur division, Bangladesh. The participants were selected at random, and data was collected via face-to-face interviews with a structured questionnaire. KAP levels were categorized as "good" or "poor" and "positive" or "negative" using a scoring method with a 60 % cut-off. The analysis comprised the utilization of descriptive statistic as well as logistic regression models.

RESULTS

The findings demonstrated that most respondents were male (85.2 %), aged 31-40 (32.8 %), with higher education (27.9 %), and vaccination training (28.7 %). While 73.8 % of farmers knew about vaccines, only 39.8 % understood their role in preventing illness from infected animals, and 40.2 % in reducing antibiotic use. Notably, 61.5 % were aware of negative drawbacks, and 59.4 % reported vaccinating their ruminant herds. Most farmers (62.7 %) don't check the expiration dates on vaccine or properly dispose of vials (81.6 %), which poses environmental and public health hazards. Overall, 46.3 %, 55.3 %, and 27.8 % of the farmers had good knowledge, a positive attitude, and good practices, respectively. Multivariable analyses revealed that male farmers aged 41-50 with a higher secondary education, over 15 years of dairy farming experience, and vaccination training were more likely to have good knowledge of vaccine usage. Accordingly, positive attitudes were associated with male farmers with graduate degrees who had vaccination training. Similarly, trained farmers were more likely to have good vaccination practices.

CONCLUSIONS

The study reveals farmers' KAP score gaps. It is critical to develop targeted educational and training initiatives to successfully address knowledge and practice gaps regarding vaccine usage and prevent potential large ruminant diseases.

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.

Are we ready for the next anthrax outbreak? Lessons from a simulation exercise in a rural-based district in Uganda

Anthrax is a bacterial zoonotic disease caused by Bacillus anthracis. We qualitatively examined facilitators and barriers to responding to a potential anthrax outbreak using the capability, opportunity, motivation behaviour model (COM-B model) in the high-risk rural district of Namisindwa, in Eastern Uganda. We chose the COM-B model because it provides a systematic approach for selecting evidence-based techniques and approaches for promoting the behavioural prompt response to anthrax outbreaks. Unpacking these facilitators and barriers enables the leaders and community members to understand existing resources and gaps so that they can leverage them for future anthrax outbreaks.This was a qualitative cross-sectional study that was part of a bigger anthrax outbreak simulation study conducted in September 2023. We conducted 10 Key Informant interviews among key stakeholders. The interviews were audio recorded on Android-enabled phones and later transcribed verbatim. The transcripts were analyzed using a deductive thematic content approach through Nvivo 12.The facilitators were; knowledge of respondents about anthrax disease and anthrax outbreak response, experience and presence of surveillance guidelines, availability of resources, and presence of communication channels. The identified barriers were; porous boarders that facilitate unregulated animal trade across, lack of essential personal protective equipment, and lack of funds for surveillance and response activities.Generally, the district was partially ready for the next anthrax outbreak. The district was resourced in terms of human resources but lacked adequate funds for animal, environmental and human surveillance activities for anthrax and related response. The district technical staff had the knowledge required to respond to the anthrax outbreak but lacked adequate funds for animal, environmental and human surveillance for anthrax and related response. We think that our study findings are generalizable in similar settings and therefore call for the implementation of such periodic evaluations to help leverage the strong areas and improve other aspects. Anthrax is a growing threat in the region, and there should be proactive efforts in prevention, specifically, we recommend vaccination of livestock and further research for human vaccines.

Syndemic Challenges: Addressing the Resurgence of Mpox Amidst Concurrent Outbreaks in the DRC

The Democratic Republic of Congo (DRC) faces a syndemic of infectious diseases, including monkeypox (mpox), cholera, measles, anthrax, and plague, worsening public health challenges and socioeconomic disparities. This review synthesizes and discusses epidemiological data and consequences of simultaneous outbreaks in the DRC between January 2023 and March 2024. The findings highlight a 6.7% fatality rate and 3319 confirmed cases of mpox, with significant outbreaks in Kinshasa and 22 other provinces. Anthrax occasionally surfaced among cattle-raising villages, measles affected fewer than five children susceptible to the disease, and cholera outbreaks persisted in North Kivu, South Kivu, and Tanganyika. Plague incidences, mostly bubonic, have been reported in Ituri province. Vulnerable groups, including children, mothers, the elderly, and those with compromised immune systems, face increased risks due to poor healthcare access, hunger, and underlying medical conditions. Cultural beliefs, healthcare system issues, and socioeconomic instability impede effective response tactics. This strain on the fragile healthcare system highlights the need for increased surveillance, immunization efforts, and community involvement. To mitigate the effects of syndemic outbreaks, strengthening the DRC's health systems through international cooperation, integrated public health initiatives, and improved access to healthcare is crucial.

Comprehensive Spatial-Temporal and Risk Factor Insights for Optimizing Livestock Anthrax Vaccination Strategies in Karnataka, India

Anthrax, a zoonotic disease affecting both livestock and humans globally, is caused by Bacillus anthracis. The objectives of this study were the following: (1) to identify environmental risk factors for anthrax and use this information to develop an improved predictive risk map, and (2) to estimate spatial variation in basic reproduction number (Ro) and herd immunity threshold at the village level, which can be used to optimize vaccination policies within high-risk regions. Based on the anthrax incidences from 2000-2023 and vaccine administration figures between 2008 and 2022 in Karnataka, this study depicted spatiotemporal pattern analysis to derive a risk map employing machine learning algorithms and estimate Ro and herd immunity threshold for better vaccination coverage. Risk factors considered were key meteorological, remote sensing, soil, and geographical parameters. Spatial autocorrelation and SaTScan analysis revealed the presence of hotspots and clusters predominantly in the southern, central, and uppermost northern districts of Karnataka and temporal cluster distribution between June and September. Factors significantly associated with anthrax were air temperature, surface pressure, land surface temperature (LST), enhanced vegetation index (EVI), potential evapotranspiration (PET), soil temperature, soil moisture, pH, available potassium, sulphur, and boron, elevation, and proximity to waterbodies and waterways. Ensemble technique with random forest and classification tree models were used to improve the prediction accuracy of anthrax. High-risk areas are expected in villages in the southern, central, and extreme northern districts of Karnataka. The estimated Ro revealed 11 high-risk districts with Ro > 1.50 and respective herd immunity thresholds ranging from 11.24% to 55.47%, and the assessment of vaccination coverage at the 70%, 80%, and 90% vaccine efficacy levels, all serving for need-based strategic vaccine allocation. A comparison analysis of vaccinations administered and vaccination coverage estimated in this study is used to illustrate difference in the supply and vaccine force. The findings from the present study may support in planning preventive interventions, resource allocation, especially of vaccines, and other control strategies against anthrax across Karnataka, specifically focusing on predicted high-risk regions.

Knowledge, attitude and practice related to anthrax among livestock farmers in West Kazakhstan

BACKGROUND

Anthrax is the most prioritized zoonotic disease in Kazakhstan due to its threatening potential to the public health and agricultural sector. Sporadic anthrax outbreaks are being reported annually among human and livestock populations throughout the country, with the highest frequency occurring in West Kazakhstan.

METHODS

A cross-sectional study was conducted using a survey-based face-to-face interview. From January to May 2022, 489 randomly selected participants were surveyed in 6 districts of the Baiterek province in West Kazakhstan oblast to evaluate the knowledge, attitude and practice (KAP) regarding anthrax among community members. This is the first KAP study conducted relating to outbreaks of anthrax in Kazakhstan.

RESULTS

In this study, most participants (74%) surveyed were males, and 40% of respondents had a secondary level education. Overall, 91% of the community respondents were engaged in agriculture and livestock rearing. Among these community members, cattle rearing was the most common (67%) occupation compared to other livestock species. Additionally, over a 50% of the population studied had no knowledge about the zoonotic nature of the disease, and about 82% and 87% of respondents were unaware of any animal and human anthrax symptoms, respectively. About 70% of the respondents were interested in vaccinating their livestock against anthrax. Individuals aged 45-54 displayed notably higher animal vaccination rates (45%; 95% CI: 38.4-52.0; p < 0.025) compared to those aged 25-34 and 65-74. Respondents residing in the Beles district (20%; 95% CI: 17.1-24.7; p < 0.005) exhibited a significantly higher level of awareness concerning the fatality of anthrax in contrast to participants from Bolashak. Roughly 61% of respondents held the belief that anthrax is a lethal disease. An overwhelming majority of the survey participants (99%) affirmed their non-participation in the slaughter of infected animals.

CONCLUSION

The findings of this study indicate that KAP among community members relating to anthrax is low and requires swift implementation of education programmes in building awareness of anthrax under the One Health approach, especially in anthrax prone regions.

A survey on the knowledges, attitudes, behaviours and practices of goat farmers about peste des petits ruminants disease in goats at Haor and bordered areas in Sylhet district of Bangladesh

BACKGROUND

Contagious and economically devastating, peste des petits ruminants (PPR) is a viral disease affecting goats and sheep, causing significant losses in livestock productivity and posing a threat to food security and rural livelihoods worldwide.

OBJECTIVES

This study was conducted to assess the status of goat farmer's knowledge, attitude and practice (KAP) about PPR disease at Sylhet district of Bangladesh.

METHODS

A comprehensive cross-sectional survey, conducted over 11 weeks, targeted 130 goat owners. Following a pilot study with 20 farmers, a set of 17 validated questions on PPR KAP was validated. Data collection was performed through face-to-face interviews by a trained team using KOBO Toolbox, with interpretation of responses based on established thresholds for knowledge (>65%), attitude (>75%) and practice (>70%).

RESULTS

Overall, 67.7% of participants demonstrated a good level of knowledge about PPR disease. Males exhibited 1.42 times higher odds of knowledge compared to females (odds ratio = 1.42). The middle age group (31-45 years) showed significantly higher knowledge levels (83.3%, p < 0.001). Within this age group, positive practice levels were also notably higher (54.8%). Those with a higher secondary education background exhibited the most positive practice levels (>80%). Participants whose additional income came from non-governmental organization employment showed a higher positive practice level (71.4%), 1.46 times higher than other income sources.

CONCLUSION

Strategic interventions should prioritize female farmers, educational empowerment and collaboration with non-governmental organizations to bolster livestock health and rural livelihoods in Bangladesh as part of national PPR control strategy to fulfil the goals of Office International des Epizooties/World Organization for Animal Health (OIE/WOAH) and Food and Agriculture Organization (FAO) PPR eradication by 2030.

Animal, human, and environmental perspectives on anthrax in Bangladesh

Background

In Bangladesh, the zoonotic transmission of anthrax from animals to humans poses substantial challenges for prevention and control programs, especially in resource-constrained settings. A comprehensive literature review was conducted focusing on anthrax infections in animals, humans, and the environment to enable better design of prevention and control strategies.

Materials and methods

We followed PRISMA guidelines to collect data on anthrax infection in animals and humans from reports between 1980 and January 2023. We used a standardized data extraction template to collect data on study location, year, hosts, deaths and risk factors responsible for anthrax occurrences at the animal, human and environmental sectors. Subsequently, we conducted a thorough analysis of the data gathered to identify the factors responsible for anthrax occurrences and to propose updated strategies for anthrax prevention and control.

Results

Of the 27 articles analyzed, 20 focused on animal or human anthrax, while seven addressed environmental contaminations. A total of 6354 cases of anthrax infection in animals were recorded, with 998 fatalities and an overall case fatality of 15.7 %. In humans, inadequate knowledge about anthrax and its transmission was a significant factor. Risk factors for human cutaneous anthrax included activities such as slaughtering diseased animals and contact with contaminated raw meat or blood. Risky practices such as disposal of animal carcasses in floodwaters or water bodies were observed in some areas, contributing to the persistence of the anthrax pathogen in the environment.

Conclusions

Our study highlights the necessity of a multisectoral One Health approach to effectively control and prevent anthrax outbreaks in both animals and humans. This approach should include comprehensive vaccination programs, social and behavioral change activities, environmental management, and the establishment of surveillance systems. Implementing these recommendations will be crucial in addressing the complex challenges posed by anthrax in low-resource settings.

Cutaneous Anthrax in a Farmer Man: A Case Report

Introduction:

Anthrax is an acute infection caused by Bacillus anthracis, an anaerobic, spore-forming, Gram-positive bacterium. Anthrax disease is a common disease among herbivores and humans that is transmitted to humans through direct contact with farm animals that are sick or have died of anthrax.

Case Summary:

A 43-year-old man having livestock as a profession had a cutaneous anthrax infection on the dorsal surface of his left thumb. The patient was infected with anthrax by slaughtering a sheep infected with Bacillus anthracis. He was treated with penicillin after an early diagnosis of anthrax bacillus.

Conclusion:

Anthrax infection is a highly contagious disease, and early detection is very important. There is a need to strengthen the health care system for farm animals and educate farmers on how not to consume the meat of diseased carcasses and how to dispose them of hygienically, especially in high-risk areas.
