Emergence and dissemination of monkeypox, an intimidating global public health problem

Effectiveness of educational intervention for improving Monkeypox (Mpox) viral infection knowledge among MSM population

BACKGROUND

Mpox is a zoonotic disease caused by the mpox virus (MPXV), which has recently exhibited human-to-human transmission globally. Due to its hidden nature and high-risk behaviors, men who have sex with men (MSM) has become a focal point for mpox prevention and control. This study evaluates the impact of health interventions on mpox knowledge awareness among MSM.

METHODS

Through pre- and post-MIP surveys, we analyzed the awareness of mpox knowledge, preferences for acquiring mpox information, and preferred channels among MSM. Data collection occurred from August 2023 to March 2024, with a total of 1514 valid questionnaires collected. The Mpox Intervention Program (MIP) included the development and distribution of educational materials, Voluntary Counseling and testing (VCT) clinic consultations, and surveys.

RESULTS

Post-intervention, the total score for mpox knowledge awareness significantly increased from 58.50 to 68.47 (P <0.001), and the knowledge awareness rate rose from 48.66 % to 64.60 % (P <0.001). The intervention significantly improved participants' understanding of mpox incubation period, asymptomatic infections, transmission routes, and prevention measures (P <0.001). MSM preferred obtaining mpox knowledge through new media and internet social platforms, with no significant changes in preferences pre- and post-MIP.

CONCLUSION

The MIP effectively improved mpox knowledge awareness and cognitive levels among MSM. These findings provide scientific evidence for optimizing health education strategies and controlling the spread of mpox.

From Gut Microbiomes to Infectious Pathogens: Neurological Disease Game Changers

Gut microbiota and infectious diseases affect neurological disorders, brain development, and function. Compounds generated in the gastrointestinal system by gut microbiota and infectious pathogens may mediate gut-brain interactions, which may circulate throughout the body and spread to numerous organs, including the brain. Studies shown that gut bacteria and disease-causing organisms may pass molecular signals to the brain, affecting neurological function, neurodevelopment, and neurodegenerative diseases. This article discusses microorganism-producing metabolites with neuromodulator activity, signaling routes from microbial flora to the brain, and the potential direct effects of gut bacteria and infectious pathogens on brain cells. The review also considered the neurological aspects of infectious diseases. The infectious diseases affecting neurological functions and the disease modifications have been discussed thoroughly. Recent discoveries and unique insights in this perspective need further validation. Research on the complex molecular interactions between gut bacteria, infectious pathogens, and the CNS provides valuable insights into the pathogenesis of neurodegenerative, behavioral, and psychiatric illnesses. This study may provide insights into advanced drug discovery processes for neurological disorders by considering the influence of microbial communities inside the human body.

MPXV infection impairs IFN response but is partially sensitive to IFN-γ antiviral effect

The recent outbreak of monkeypox virus (MPXV) has caused global concern. How the virus evades the interferon (IFN) response is still poorly understood. We analyzed type I/II IFN (IFN-I/II) expression in clinical samples from MPXV-infected patients and measured IFN-I kinetics in MPXV-infected cells. We also evaluated the anti-MPXV activity of IFN-I/II in A549, HeLa and Vero-E6 cell lines. IFN-I/II mRNA expression was detected in skin lesions, anal swabs, nasopharyngeal samples and peripheral blood mononuclear cells (PBMC), with the highest levels in skin lesions (p < 0.05). High MPXV DNA levels in clinical samples were associated with increased IFN-I levels. In vitro, MPXV infection induced a peak of IFN-I between 48 and 72 h post-infection (p < 0.01). Pre-treatment of the A549, HeLa and Vero-E6 cells with high concentrations (≥ 100,000 International Unit, IU/ml) of IFN-α and IFN-ω did not inhibit or had little effect on MPXV replication, while IFN-β moderately reduced MPXV replication by 2.7-1.5 log10 at 100,000 IU/ml. In clinical samples there was a trend for elevated levels of IFN-γ in association with lower MPXV load and in vitro IFN-γ (3,600 IU/ml) strongly reduced viral titers by 3.4-1.6 log10. There were no significant differences in expression of select IFN-stimulated genes (ISGs) in MPXV infection in vitro. This study shows that MPXV delays IFN-I induction and inhibits expression of selected ISGs in vitro and is associated with an IFN-I resistance phenotype in vivo. However, MPXV is less resistant to IFN-γ in vivo and is sensitive to IFN-γ treatment in vitro, suggesting a potential therapeutic role for IFN-γ.

Mpox outbreak: Time series analysis with multifractal and deep learning network

This article presents an overview of an mpox epidemiological situation in the most affected regions-Africa, Americas, and Europe-tailoring fractal interpolation for pre-processing the mpox cases. This keen analysis has highlighted the irregular and fractal patterns in the trend of mpox transmission. During the current scenario of public health emergency of international concern due to an mpox outbreak, an additional significance of this article is the interpretation of mpox spread in light of multifractality. The self-similar measure, namely, the multifractal measure, is utilized to explore the heterogeneity in the mpox cases. Moreover, a bidirectional long-short term memory neural network has been employed to forecast the future mpox spread to alert the outbreak as it seems to be a silent symptom for global epidemic.

High Global Health Security Index is a determinant of early detection and response to monkeypox: A cross-sectional study

INTRODUCTION

Recent outbreaks of monkeypox (Mpox) have occurred in countries outside of Africa, with large numbers of cases spreading rapidly to almost every continent. We aimed to analyze the correlation between the Global Health Security (GHS) Index (categories and indicators) and the Mpox case rate in different regions and globally.

METHODS

In this cross-sectional study, we used data from Mpox cases from the WHO, and the GHS categories and indicators for detection, prevention, reporting, health system, rapid response, international norms compliance, and risk environment. Outcome measures were the relationship between GHS index (categories and indicators) and Mpox case rate using crude and adjusted non-linear regression models.

RESULTS

After performing adjusted analyses, only risk environment and detection and reporting index were associated with Mpox case rates in the 99 countries and the Region of the Americas, respectively. Antimicrobial resistance (AMR) indicators of the prevention category, risk communication of the rapid response category, the joint external evaluation and performance veterinary services of the norms category, and the infrastructure adequacy of the risk environment category were associated with Mpox case rates in the 99 countries (p<0.05). Laboratory systems strength and quality indicator of the detection and reporting category, and emergency response operation indicator of the response rapid category were associated with Mpox case rates in the countries of the region of the Americas (p<0.05). AMR indicator of the prevention of the emergence category, and the infrastructure adequacy of the risk environment category were associated with Mpox case rates in the countries of the European Region (p<0.05). In the countries of the other regions, only the trade and travel restrictions indicator of the rapid response category was associated with Mpox case rates (p<0.05).

CONCLUSIONS

Countries, particularly in the Americas region, with high levels of infrastructure adequacy and laboratory system strength and quality as measured by the GHS index are better equipped to detect more Mpox cases. Therefore, they have higher Mpox case detection rates and can successfully respond to Mpox outbreaks.

The Feasibility of Elimination of Monkeypox Virus in Nigeria: A Systematic Review

Monkeypox is a zoonotic virus with an increasing incidence in Nigeria, posing significant public health challenges. The virus, related to smallpox, primarily spreads through direct contact with infected animals or humans and has been noted for its potential for wider transmission due to changing ecological and social dynamics. This research aims to evaluate the feasibility of eliminating monkeypox in Nigeria through integrated approaches involving vaccination, public health strategies, and ecological management. Additionally, it seeks to propose a unified public health strategy, incorporating One Health principles, to achieve the elimination of monkeypox in Nigeria. A review of the feasibility of eliminating the monkeypox virus in Nigeria was conducted using databases like Science Direct, Cochrane, PubMed, and Medline. The search was guided by the methodologies and reporting guidelines of the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). The initial search yielded 89 publications, but the number of articles that required examination was reduced after applying selected keywords and evaluating abstracts. We deemed 32 articles relevant to the subject after applying inclusion and exclusion criteria. The findings are analyzed, highlighting their limitations and strengths and discussing practical implications, knowledge gaps, and recommendations for future research. This study provides evidence supporting the feasibility of the elimination of the monkeypox virus in Nigeria. Strategic recommendations for a sustainable public health approach to eliminating monkeypox emphasize preventive measures, community engagement, and ecological preservation. This study will provide critical insights into the feasibility of eliminating monkeypox in Nigeria, offering a model that can be adapted for other regions facing similar challenges. The integration of health, ecological, and community-focused strategies is expected to contribute significantly to global efforts to control and potentially eradicate monkeypox. This research could serve as a foundational study for public health authorities in Nigeria and internationally, informing policy and operational decisions to control and eliminate monkeypox as a public health threat. The monkeypox virus reemerges in Nigeria, increasing mortality rates. Awareness programs should be conducted on its danger, transmission mode, and potential human transmission. Public education on the lack of treatment and vaccines is crucial. Meat inspection laws should be enforced to ensure safe animal consumption.

Halogenated Secondary Metabolites from Higher Plants: Potent Drug Candidates for Chikungunya Using in silico Approaches

Chikungunya virus (CHIKV) causes a debilitating fever and joint pain, with no specific antiviral treatment available. Halogenated secondary metabolites from plants are a promising new class of drug candidates against chikungunya, with unique properties that make them effective against the virus. Plants produce these compounds to defend themselves against pests and pathogens, and they are effective against a wide range of viruses, including chikungunya. This study investigated the interactions of halogenated secondary metabolites with nsP2pro, a therapeutic target for CHIKV. A library of sixty-six halogenated plant metabolites screened previously for ADME properties was used. Metabolites without violation of Lipinski's rule were docked with nsP2pro using AutoDock Vina. To find the stability of the pipoxide chlorohydrin-nsP2pro complex, the GROMACS suite was used for MD simulation. The binding free energy of the ligand-protein complex was computed using MMPBSA. Molecular docking studies revealed that halogenated metabolites interact with nsP2pro, suggesting they are possible inhibitors. Pipoxide chlorohydrin showed the greatest affinity to the target. This was further confirmed by the MD simulations, surface accessible area, and MMPBSA studies. Pipoxide chlorohydrin, a halogenated metabolite, was the most potent against nsP2pro in the survey.

Knowledge, Attitude and Associated Factors of Monkeypox Infection Among Healthcare Workers in Injibara General Hospital, Northwest Ethiopia

Background

Fighting health threats, especially the rise of new infectious diseases, is one of the main responsibilities of healthcare workers. However, their knowledge and attitudes toward monkeypox have not yet been assessed. Therefore, this study aimed to assess the knowledge, attitude, and factors associated with monkeypox infection among healthcare workers at Injibara General Hospital, Northwest Ethiopia.

Methods

Institution-based cross-sectional study was conducted from December 1-30, 2022. Data were collected using a structured self-administered questionnaire. A simple random sampling technique was used to select study participants. Descriptive statistics and multivariable logistic regression analyses were computed. The degree of association was interpreted using an odds ratio with a 95% confidence interval and a p-value < 0.05.

Results

Among the 200 healthcare workers who participated, 38.5% (95% CI: 32.5%-45%) and 62% (95% CI: 55-68.5%) had good knowledge and positive attitudes regarding monkeypox respectively. Having a master's degree or above (AOR = 11.25: 95% CI: 2.03-62.33), being vaccinated against COVID-19 (AOR = 2.60: 95% CI: 1.37-4.94), and having access to information about monkeypox (AOR = 3.37: 95% CI: 1.33-8.50) were the factors associated with good knowledge. Furthermore, a positive attitude was significantly associated with being 30 years of age or older (AOR = 2.95: 95% CI: 1.55-5.60) and having access to information about monkeypox (AOR = 4.14: 95% CI: 2.06, 8.30).

Conclusion

Both good knowledge and positive attitudes were relatively low among healthcare workers. Factors such as age, education level, COVID-19 vaccination status, and access to information about monkeypox were significantly associated with the knowledge and attitude of healthcare workers. To enhance the knowledge and attitude of healthcare workers, hospitals should consider offering educational upgrades, hosting educational events like seminars, conferences, webinars, and campaigns, and ensuring comprehensive coverage of the topic in medical curricula.

An overview on mRNA-based vaccines to prevent monkeypox infection

The human monkeypox virus (Mpox) is classified as a member of the Poxviridae family and belongs to the Orthopoxvirus genus. Mpox possesses double-stranded DNA, and there are two known genetic clades: those originating in West Africa and the Congo Basin, commonly known as Central African clades. Mpox may be treated with either the vaccinia vaccination or the therapeutics. Modifying the smallpox vaccine for treating and preventing Mpox has shown to be beneficial because of the strong link between smallpox and Mpox viruses and their categorization in the same family. Cross-protection against Mpox is effective with two Food and Drug Administration (FDA)-approved smallpox vaccines (ACAM2000 and JYNNEOSTM). However, ACAM2000 has the potential for significant adverse effects, such as cardiac issues, whereas JYNNEOS has a lower risk profile. Moreover, Mpox has managed to resurface, although with modified characteristics, due to the discontinuation and cessation of the smallpox vaccine for 40 years. The safety and efficacy of the two leading mRNA vaccines against SARS-CoV-2 and its many variants have been shown in clinical trials and subsequent data analysis. This first mRNA treatment model involves injecting patients with messenger RNA to produce target proteins and elicit an immunological response. High potency, the possibility of safe administration, low-cost manufacture, and quick development is just a few of the benefits of RNA-based vaccines that pave the way for a viable alternative to conventional vaccines. When protecting against Mpox infection, mRNA vaccines are pretty efficient and may one day replace the present whole-virus vaccines. Therefore, the purpose of this article is to provide a synopsis of the ongoing research, development, and testing of an mRNA vaccine against Mpox.

Monkeypox virus infections in low-risk groups during the 2022-23 global outbreak: An analysis of the WHO global report

Introduction

In the 2022-23 Mpox outbreak, cases also occurred in children, adolescents, and adults aged 50 years and older, for whom the risk of transmission is low and whose epidemiological characteristics are less known, compared to high-risk groups such as young adults. Here we describe the epidemiological characteristics of Mpox in children, adolescents and adults aged 50 years and older in the global Mpox outbreak.

Methods

A retrospective study on laboratory-confirmed surveillance data of Mpox cases reported to World Health Organization (WHO) was conducted. Case data from WHO's 2022-23 Mpox Outbreak: Global Trends from 1 January 2022 to 1 September 2023 was used for our analysis. We included cases reported by WHO with data on age (children [range, 0 to 9 years], adolescents [range, 10 to 17 years], adults 50 to 59 years, and adults 60 years and older), gender, WHO region, hospital admission, and intensive care unit admission.

Results

Until September 01, 2023, data from 89,752 cases of Mpox have been reported to WHO. Of all the reported cases, 1124 (1.3%), 6296 (7.0%) and 1501 (1.6%) were children and adolescents, adults aged 50-59 years, and adults aged 60 years or older, respectively, and the proportion varied among WHO regions. There was a high proportion of cases among population aged 0-17 years, adolescents (256 [66.3%]) from the region of the Americas and girls aged 0-9 years [127 (46.7%)] from the African region. Men aged 50-59 years (3495 [57.2%] vs. 2553 [41.8%] cases from the region of the Americas and the European region, respectively) and men aged 60-69 years (639 [60.0%] vs. 607 [48.4%] from the region of the Americas and the European region) were most affected, compared to other age groups and women. Among children, adolescents, and adults aged 50 years or older, a low proportion of cases developed some complications and required hospital admission, and some cases were admitted to the intensive care unit.

Conclusions

Epidemiological evidence of Mpox in these low-risk groups highlights the risk of wider community transmission. Therefore, while efforts continue to control the global outbreak of Mpox in high-risk groups, it is also necessary to ensure that these low-risk groups have access to timely health care and vaccination.

Human monkeypox: An updated appraisal on epidemiology, evolution, pathogenesis, clinical manifestations, and treatment strategies

Monkeypox (Mpox) is a zoonotic viral disease caused by the monkeypox virus (MPXV), a member of the Orthopoxvirus genus. The recent occurrence of Mpox infections has become a significant global issue in recent months. Despite being an old disease with a low mortality rate, the ongoing multicountry outbreak is atypical due to its occurrence in nonendemic countries. The current review encompasses a comprehensive analysis of the literature pertaining to MPXV, with the aim of consolidating the existing data on the virus's epidemiological, biological, and clinical characteristics, as well as vaccination and treatment regimens against the virus.

Molecular Methods for Diagnosis of Monkeypox: A Mini-review

BACKGROUND

Monkeypox is a global public health issue caused by the monkeypox virus (MPXV). As of October 28, 2022, a total of 77,115 laboratoryconfirmed cases and 3,610 probable cases, including 36 deaths, were reported, with 9,070 cases reported in Brazil, the second most affected country. The need to develop national technologies for the rapid diagnosis of emerging diseases for mass testing of the population is evident, as observed in the SARS-CoV-2 pandemic.

OBJECTIVE

With that in mind, this article provides an overview of current methods, techniques, and their applications in the molecular detection of monkeypox, focusing the search on real-time polymerase chain reaction (qPCR), polymerase chain reaction (PCR), and polymerase chain reaction-enzyme linked immunosorbent assay (PCRELISA).

METHODS

The relevant documents or papers covered in this study were selected by a search in international bibliographic databases. The search terms used in the databases were aimed at summarizing existing knowledge on molecular diagnostic methods, such as monkeypox; MPX, MPXV, qPCR, PCR, PCR-ELISA, diagnosis and detection searched separately or together using the Boolean operator "AND" either in the title or abstract. The searches took place in September 2022, and the corresponding articles were selected between 2012 and 2022.

RESULTS

We found 256 documents in total and twelve studies addressing the molecular diagnosis of monkeypox were classified as possible sources for this review.

CONCLUSION

It is evident there is a pressing need to develop national technologies for rapid diagnosis of emerging diseases for mass testing of the population. It is also extremely important to have national detection kits with greater diagnostic capacity to assist in developing effective public policies in countries affected by this disease.

Monkeypox Diagnosis in Clinical Settings: A Comprehensive Review of Best Laboratory Practices

An outbreak of monkeypox (Mpox) was reported in more than 40 countries in early 2022. Accurate diagnosis of Mpox can be challenging, but history, clinical findings, and laboratory diagnosis can establish the diagnosis. The pre-analytic phase of testing includes collecting, storing, and transporting specimens. It is advised to swab the lesion site with virus transport medium (VTM) containing Dacron or polyester flock swabs from two different sites. Blood, urine, and semen samples may also be used. Timely sampling is necessary to obtain a sufficient amount of virus or antibodies. The analytical phase of infectious disease control involves diagnostic tools to determine the presence of the virus. While polymerase chain reaction (PCR) is the gold standard for detecting Mpox, genome sequencing is for identifying new or modified viruses. As a complement to these methods, isothermal amplification methods have been designed. ELISA assays are also available for the determination of antibodies. Electron microscopy is another effective diagnostic method for tissue identification of the virus. Wastewater fingerprinting provides some of the most effective diagnostic methods for virus identification at the community level. The advantages and disadvantages of these methods are further discussed. Post-analytic phase requires proper interpretation of test results and the preparation of accurate patient reports that include relevant medical history, clinical guidelines, and recommendations for follow-up testing or treatment.

The Global Health Threat of Monkeypox Virus: Understanding Its Biology, Transmission, and Potential Therapeutic Interventions

Monkeypox virus (MPXV), a member of the Orthopoxvirus genus, shares its genus with Variola virus (VARV), the causative agent of smallpox, and Vaccinia virus (VACV), used for smallpox vaccination. While smallpox has been eradicated, MPXV and related poxviruses continue to pose a global health threat. Monkeypox (Mpox), similar in clinical presentation to smallpox but milder, is endemic in Central and West Africa. Sporadic outbreaks emphasize the potential for wider dissemination. Understanding their biology, transmission, immune evasion, and clinical features informs disease control strategies. The intersection of medical innovation and biotechnology with poxviruses underscores their importance in both disease and scientific advancement. Further research is essential to enhance prevention, management, and therapeutic interventions for these viruses.

Comprehensive overview of 2022 human monkeypox outbreak and its pathology, prevention, and treatment: A strategy for disease control

The 2022 Monkeypox virus, an evolved DNA strain originating in Africa, exhibits heightened human-to-human transmissibility and potential animal transmission. Its host remains unidentified. While its initial slow transmission rate restrained global impact, 2022 saw a surge in cases, causing widespread concern in over 103 countries by September. This virus's distinctive human-to-human transmission marks a crucial shift, demanding a prompt revaluation of containment strategies. However, the host source for this shift requires urgent research attention. Regrettably, no universal preventive or curative methods have emerged for this evolved virus. Repurposed from smallpox vaccines, only some vaccinations offer a partial defense. Solely one therapeutic drug is available. The article's essence is to provide a comprehensive grasp of the virus's epidemiology, morphology, immune invasion mechanisms, and existing preventive and treatment measures. This knowledge equips researchers to devise strategies against its spread and potential public health implications.

Frontiers of monkeypox research: An analysis from the top 100 most influential articles in the field

BACKGROUND

Monkeypox (MPX) has made recurrence after decades as a neglected zoonotic disease. More nations have reported endemic monkeypox in the past decade than in the previous forty. The World Health Organization has warned that the world may face another significant challenge after dealing with COVID-19, a pandemic, and the Monkeypox outbreak. Early appraisal of monkeypox research and development allows researchers to anticipate solutions for large outbreaks. We conducted a bibliometric analysis of this study's top 100 cited papers to identify regional research patterns.

METHODS

Our method was to search the SCI-Expanded database on Web of Science (WOS) for the top 100 papers that were cited in MPX on this database. We examined relevant literature from different years, journals, countries/regions, institutions, authors, and keywords.In order to create knowledge maps, we used the programs VOSviewer, Citespace, Scimago Graphica and the bibliometric online analysis platform. After compiling the relevant literature in Excel, we could estimate the field's focus and trends.

RESULTS

A total of 47 journals from 36 countries and regions published the top 100 cited papers between 1999 and 2023. The majority of articles were published in EMERGING INFECTIOUS DISEASES, while the highest average number of citations per paper were found in the NEW ENGLAND JOURNAL OF MEDICINE. The UNITED STATES contributed the most publications, followed by ENGLAND and SWITZERLAND. As far as the total number of publications goes, the Centers for Disease Control & Prevention in the USA, the National Institute of Health in the USA, and the World Health Organization each contributed the most papers. The major categories are immunology, virology and infectious diseases. The top five keywords were infection, Congo, virus, smallpox, and transmission. The cluster analysis suggests MPX research will focus on safe and effective vaccines and epidemic prevention.

CONCLUSION

By using bibliometric analysis, MPX researchers can quickly and visually identify their research focus and boundaries. Although studies suggest that antiviral medicine is the best treatment, creating an effective vaccine might lessen and avoid MPX pandemics in the long term. Our findings imply that safe and effective vaccines may be the focus and trends for future MPX research. International coordination for case monitoring and identification is essential to understand monkeypox disease's ever-changing epidemiology.

International coordination for case monitoring and identification is essential to understand monkeypox disease's ever-changing epidemiology.

Progress and prospects on vaccine development against monkeypox infection

The monkeypox virus (MPOX) is an uncommon zoonotic illness brought on by an orthopoxvirus (OPXV). MPOX can occur with symptoms similar to smallpox. Since April 25, 2023, 110 nations have reported 87,113 confirmed cases and 111 fatalities. Moreover, the outspread prevalence of MPOX in Africa and a current outbreak of MPOX in the U.S. have made it clear that naturally occurring zoonotic OPXV infections remain a public health concern. Existing vaccines, though they provide cross-protection to MPOX, are not specific for the causative virus, and their effectiveness in the light of the current multi-country outbreak is still to be verified. Furthermore, as a sequel of the eradication and cessation of smallpox vaccination for four decades, MPOX found a possibility to re-emerge, but with distinct characteristics. The World Health Organization (WHO) suggested that nations use affordable MPOX vaccines within a framework of coordinated clinical effectiveness and safety evaluations. Vaccines administered in the smallpox control program and conferred immunity against MPOX. Currently, vaccines approved by WHO for use against MPOX are replicating (ACAM2000), low replicating (LC16m8), and non-replicating (MVA-BN). Although vaccines are accessible, investigations have demonstrated that smallpox vaccination is approximately 85% efficient in inhibiting MPOX. In addition, developing new vaccine methods against MPOX can help prevent this infection. To recognize the most efficient vaccine, it is essential to assess effects, including reactogenicity, safety, cytotoxicity effect, and vaccine-associated side effects, especially for high-risk and vulnerable people. Recently, several orthopoxvirus vaccines have been produced and are being evaluated. Hence, this review aims to provide an overview of the efforts dedicated to several types of vaccine candidates with different strategies for MPOX, including inactivated, live-attenuated, virus-like particles (VLPs), recombinant protein, nucleic acid, and nanoparticle-based vaccines, which are being developed and launched.

A Case of Concurrent Infection With Syphilis and Monkeypox in an Immunosuppressed Individual

Monkeypox and syphilis are two distinct infectious diseases that can cause severe health complications in infected patients and can share clinical manifestations, making their simultaneous occurrence challenging to diagnose and manage. Here, we present a case report of a patient with the coinfection of monkeypox and syphilis, highlighting the clinical presentation and treatment considerations. This case underlines the importance of considering coinfections in patients presenting with atypical clinical manifestations and risk factors. This case highlights the importance of early diagnosis and prompt intervention in managing patients with infectious diseases, particularly when dealing with multiple infections. Increased awareness among healthcare professionals regarding the potential for concurrent infections can enhance diagnostic accuracy and improve patient care in similar challenging cases.

Monkeypox Outbreak in Peru

Monkeypox (Mpox) is a zoonotic disease caused by the Orthopoxvirus monkeypox virus (MPXV). Since 1970, outbreaks of MPXV have occurred in several Sub-Saharan African countries. However, from May 2022 to April 2023, recent outbreaks of Mpox occurred in several countries outside of Africa, and these cases quickly spread to over 100 non-endemic countries on all continents. Most of these cases were found in the region of the Americas and the Europe region. In Latin America, the highest all-age Mpox rates per million inhabitants were in Peru, Colombia, Chile, and Brazil. Given its global impact, Mpox was declared as an international Public Health Emergency by WHO in July 2022. MPXV infection disproportionately affects men who have sex with men and members of the HIV-infected population. Vaccination is the current strategy for controlling and preventing Mpox in high-risk groups. In this context, Peru has the fourth-highest number of Mpox cases in Latin America and faces significant challenges in disease control. Because of this, in this review, we discuss the epidemiology, public health indicators, and prevention of Mpox in the 2022 Peru outbreak so that health authorities can join forces to control MPXV transmission.

Preventing and fighting stigma: a lesson from the first Mpox in Veneto region of Northeast Italy-A case report

Since the 1970s, human monkeypox (Mpox) has been referred to as a zoonotic endemic disease of specific regions of Africa until early 2022, when a worldwide epidemic outbreak developed. There are many hypotheses on how Mpox could spread to non-endemic regions; the dominant theory is that it spread from the UK and Spain among men who have sex with men (MSM). Therefore, the first clinical case in the Veneto region (Northeast of Italy) was analyzed-which represented a typical case report of the ongoing outbreak-with lesions located mainly in the areas associated with sexual behaviors (genital and oral). This case report highlights the new challenges of Mpox, as it seems to differ from the previous classic manifestation. Indeed, although the patient achieved restitution ad integrum of lesions and complete recovery from the disease, it is deemed necessary to offer communication strategies to involve a heterogeneous audience based on different risks of exposure but without stigmatizing attitudes, avoiding the mistakes made with HIV. The need for broad public involvement is demonstrated by identifying Mpox even in "anomalous cases." Stigma could be an obstacle in engaging patients in proper care and in getting honest answers while contact tracing, as happened in our patient's case; thus, WHO recently renamed monkeypox as Mpox. Abnormal outbreaks in non-endemic countries, with no causal links, must become a warning signal for governments and health policies to design national plans for managing unexpected outbreaks. For an effective public health response, health institutions must communicate effectively, focus on changes and prevention measures, and formulate a plan based on equity and inclusion of the most vulnerable groups.

Clinical and Epidemiological Interventions for Monkeypox Management in Children: A Systematic Review

This review aims to compile the available literature on monkeypox, identify risk factors for developing the disease, and recommend effective preventative methods to reduce the number of reported cases and fatalities in children and pregnant women. In seeking out pertinent studies on monkeypox virus in children and pregnant women, we searched the literature using the databases Cochrane Library, Google Scholar, PubMed, EMBASE, Web of Science, and Scopus up to 1st February 2023. This study analyzed data from case studies of monkeypox in children and pregnant women. Clinical data and test findings of monkeypox patients less than 18 years old and pregnant women were analyzed. The Newcastle-Ottawa Scale was used to do the quality evaluation. Our record examination spanned the years 1985 to 2023 and found 17 children and five pregnant female patients treated with monkeypox in various hospitals/community centers. Zaire, Gabon, Chicago, Sierra Leone, Central African Republic, Northern DR Congo, Liberia, Cameroon, the Democratic Republic of the Congo, the United Kingdom, the Netherlands, and Florida all contributed to the 14 studies analyzed. There were no studies identified for meta-analysis of selected case studies of hospitalized children and pregnant women who were diagnosed with monkeypox. The incidence, prevalence, clinical characteristics, diagnosis, management, prevention, vaccinations, infant care, and care for expectant mothers are all discussed in this systematic review of monkeypox in children. Our research findings may provide a foundation for further focused research and the development of related recommendations or guidelines.

The Future of Epidemic and Pandemic Vaccines to Serve Global Public Health Needs

This Review initiates a wide-ranging discussion over 2023 by selecting and exploring core themes to be investigated more deeply in papers submitted to the Vaccines Special Issue on the "Future of Epidemic and Pandemic Vaccines to Serve Global Public Health Needs". To tackle the SARS-CoV-2 pandemic, an acceleration of vaccine development across different technology platforms resulted in the emergency use authorization of multiple vaccines in less than a year. Despite this record speed, many limitations surfaced including unequal access to products and technologies, regulatory hurdles, restrictions on the flow of intellectual property needed to develop and manufacture vaccines, clinical trials challenges, development of vaccines that did not curtail or prevent transmission, unsustainable strategies for dealing with variants, and the distorted allocation of funding to favour dominant companies in affluent countries. Key to future epidemic and pandemic responses will be sustainable, global-public-health-driven vaccine development and manufacturing based on equitable access to platform technologies, decentralised and localised innovation, and multiple developers and manufacturers, especially in low- and middle-income countries (LMICs). There is talk of flexible, modular pandemic preparedness, of technology access pools based on non-exclusive global licensing agreements in exchange for fair compensation, of WHO-supported vaccine technology transfer hubs and spokes, and of the creation of vaccine prototypes ready for phase I/II trials, etc. However, all these concepts face extraordinary challenges shaped by current commercial incentives, the unwillingness of pharmaceutical companies and governments to share intellectual property and know-how, the precariousness of building capacity based solely on COVID-19 vaccines, the focus on large-scale manufacturing capacity rather than small-scale rapid-response innovation to stop outbreaks when and where they occur, and the inability of many resource-limited countries to afford next-generation vaccines for their national vaccine programmes. Once the current high subsidies are gone and interest has waned, sustaining vaccine innovation and manufacturing capability in interpandemic periods will require equitable access to vaccine innovation and manufacturing capabilities in all regions of the world based on many vaccines, not just "pandemic vaccines". Public and philanthropic investments will need to leverage enforceable commitments to share vaccines and critical technology so that countries everywhere can establish and scale up vaccine development and manufacturing capability. This will only happen if we question all prior assumptions and learn the lessons offered by the current pandemic. We invite submissions to the special issue, which we hope will help guide the world towards a global vaccine research, development, and manufacturing ecosystem that better balances and integrates scientific, clinical trial, regulatory, and commercial interests and puts global public health needs first.

Monkeypox (mpox) in immunosuppressed patients

The World Health Organization (WHO) proclaimed a public health emergency in July 2022 due to the emergence of Mpox (formerly monkeypox) while the globe was still dealing with the COVID-19 epidemic. The characteristics of mpox in immunocompetent individuals are well-characterized, despite difficulties in diagnostics, immunization, and access to treatment that persist in low-income countries. Patients with weakened immune systems are more likely to spread an illness and die from it than healthy people because they cannot mount a protective immune response against it, such as a neutralizing IgG and poxvirus-specific Th1 response. A health warning on severe mpox in people who are immunocompromised due to Human Immunodeficiency virus (HIV) and other illnesses was released by the U.S. Centers for Disease Control and Prevention (CDC) on September 29, 2022. The advice does not specifically include primary immunodeficiency, but it does define other immunocompromising disorders as "having autoimmune disease with immunodeficiency as a clinical component". Both those with healthy immune systems and those with weakened immune systems, such as those who are immunosuppressed, older people, children, etc., have encountered serious health issues, but the latter group is more likely to do so. According to the advisory, "of the people with severe mpox manifestations for whom CDC has been consulted, the majority have had HIV with CD4 counts 200 cells/ml, indicating substantial immunosuppression". However, new cases are still expected to be discovered, especially in low-income countries with limited access to diagnosis, treatment, and prevention, and where a large percentage of the mpox-infected population also has advanced HIV infection. Thus, further research is always needed to determine the best way to treat mpox in immunocompromised people. In this context, we discussed /reviewed the mpox clinical presentation, available treatment options and current preventive guidelines in immunocompromised patients.

Association between public attention and monkeypox epidemic: A global lag-correlation analysis

The human monkeypox has become a public health problem globally. Google Trends Index (GTI) is an indicator of public attention, being potential for infectious disease outbreak surveillance. In this study, we used lag-correlation analysis to evaluate the spearman correlation coefficients between public attention and monkeypox epidemic by -36 to +36 days-lag in top 20 countries with most cumulated cases until September 30, 2022, the meta-analyses were performed to pool the coefficients of countries among all lags. We also constructed vector autoregression model and Granger-causality test to probe the significance of GTI in monkeypox forecasting. The strongest spearman correlation was found at lag +13 day (r = 0.53, 95% confidence interval: 0.371-0.703, p < 0.05). Meta-analysis showed significantly positive correlation when the lag was from -12 to +36 day, which was most notable on the third posterior day (lag +3 day). The pooled spearman correlation coefficients were all above 0.200 when the lag ranged from +1 to +20 day, and the causality of GTI for daily case was significant in worldwide and multiple countries. The findings suggested a robust association between 13-days-priority GTI and daily cases worldwide. This work introduced a potential monitor indicator on the early warning and surveillance of monkeypox outbreak.
