Duda R, Betoulet JM, Besombes C, Mbrenga F, Borzykh Y, Nakouné E, Giles-Vernick T. A time of decline: An eco-anthropological and ethnohistorical investigation of mpox in the Central African Republic. PLOS GLOBAL PUBLIC HEALTH 2024; 4:e0002937. [PMID: 38517925 PMCID: PMC10959331 DOI: 10.1371/journal.pgph.0002937] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Accepted: 01/29/2024] [Indexed: 03/24/2024]
Abstract
The Central African Republic (CAR) has experienced repeated mpox outbreaks since 2001. Although several mpox epidemiological risk factors for zoonotic and interhuman transmission have been documented, the reasons for more frequent epidemic outbreaks are less well understood, relying on vague explanatory categories, including deforestation, hunting, and civil unrest. To gain insight into increasingly frequent outbreaks, we undertook an ethnohistorical, eco-anthropological analysis in two CAR regions: the Lobaye prefecture, experiencing one or more annual outbreaks in the past decade, and the Sangha-Mbaere prefecture, with a longer history of mpox but less frequent outbreaks. We comparatively examined changing political economies, forest use practices, and understandings of mpox. In 2022, we conducted 40 qualitative ethnohistorical, anthropological interviews and participant-observation of forest activities in two languages (Sango and French). We compared contemporary practices with hunting, trapping, and meet consumption practices, documented through quantitative and qualitative observation in one research site, over 6 months in 1993. We find increased rodent capture and consumption in both sites in the past 30 years and expanded practices of other potentially risky activities. Simultaneously, we also identify important differences in risky practices between our Lobaye and Sangha-Mbaere participants. In addition, Lobaye and Sangha participants underscored historical processes of decline producing mpox among other emergences, but they framed these declension processes diversely as economic, political, nutritional, and moral. Our findings are important because they mobilize new types of evidence to shed light on the processual dynamics of mpox outbreaks in the CAR. This study also reveals variability across two sites within the same country, highlighting the importance of comparative, fine-grained anthropological and historical research to identify underlying dynamics of mpox outbreaks. Finally, our study points to the need for mpox interventions and risk communication accounting for these regional differences, even within a single country.

Abstract
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.

Shoaib HM. Monkeypox as a potential emerging pandemic: a discussion on future risks and preparedness in Saudi Arabia. Front Public Health 2023; 11:1254545. [PMID: 38026424 PMCID: PMC10663316 DOI: 10.3389/fpubh.2023.1254545] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Accepted: 10/19/2023] [Indexed: 12/01/2023] Open
Abstract
Monkeypox, a zoonotic disease caused by the Monkeypox virus, has emerged as a potential threat with pandemic potential in various regions. While it is challenging to predict specific outbreaks, understanding the factors contributing to Monkeypox's pandemic potential is important. This discussion paper explores the future risks and preparedness measures concerning Monkeypox in Saudi Arabia. The study reviews the past and current knowledge on the Monkeypox outbreak, including its clinical presentation, transmission dynamics (animals-to-humans and humans-to-human), epidemiology, and diagnostic methods. Furthermore, it explores the potential risk factors for the spread of Monkeypox within the Gulf Cooperation Council (GCC) countries, mainly in the Saudi Arabian context, considering factors such as urbanization and travel and trade patterns. The paper emphasizes the importance of early virus detection, surveillance systems, and laboratory capacity in vaccinating and responding to Monkeypox cases. Additionally, it highlights the future risks and preparedness in Saudi Arabia and the usage of social media during the pandemic seeking support and awareness about Monkeypox, and it also highlights the need for effective communication strategies of leaders through social media channels to disseminate accurate information to the public, healthcare providers, and policymakers. The discussion concludes by calling for collaborative efforts among health authorities, researchers, and international medical partners to enhance surveillance, develop outbreak response plans, and ensure the availability of vaccines and treatment options. This research serves as a foundation for guiding future preventive measures and strengthening the overall preparedness of Saudi Arabia in facing the potential emergence of Monkeypox as a future pandemic.

Abstract
BACKGROUND This study aims to comparatively analyze clinical features, treatment, and patient outcomes between the previous and the 2022 mpox (monkeypox) outbreaks. METHODS Five bibliographic databases were searched for studies reporting clinical features, management, and patient outcomes of mpox. Systematic review and meta-analysis were performed. RESULTS In total, 73 studies were included in the systematic review, of which 33 studies were subjected to meta-analysis. Previous outbreaks substantially affected children, whereas the 2022 outbreak primarily affected male adults, of which 94.66% (95% confidence interval [CI], 88.03-98.95) were men who have sex with men. Furthermore, 72.47% (95% CI, 51.04-89.71) reported high-risk sexual activity and the overall human immunodeficiency virus (HIV) prevalence was 37.65% (95% CI, 30.09-45.50). Skin lesions remain the typical symptom; however, their anatomic distribution differed. Systemic manifestations were common, but rectal pain was unique to the 2022 outbreak. The estimated overall fatality during past outbreaks in Africa was 4.61% (95% CI, 2.39%-7.35%), whereas 6.34% (95% CI, 3.35%-10.10%) of patients from the 2022 outbreak required hospitalization. Antiviral treatment, in particular tecovirimat, has been prescribed for a subset of patients, but the efficacy remains inconclusive. CONCLUSIONS These findings are important for better understanding the disease and guiding adequate response to mpox outbreaks.

Abstract
Human monkeypox virus is spreading globally, and more information is required about its epidemiological and clinical disease characteristics in endemic countries. We report the investigation of an outbreak in November 2021 in Central African Republic (CAR). The primary case, a hunter, fell ill after contact with a non-human primate at the frontier between forest and savannah. The ensuing investigation in a small nearby town concerned two families and four waves of inter-human transmission, with 14 confirmed cases, 11 suspected cases and 17 non-infected contacts, and a secondary attack rate of 59.5% (25/42). Complications were observed in 12 of the 19 (63.2%) confirmed and suspected cases with available clinical follow-up data: eight cases of bronchopneumonia, two of severe dehydration, one corneal ulcer, one abscess, two cutaneous superinfections, and six cutaneous sequelae (cheloid scars, or depigmentation). There was one death, giving a case fatality ratio of 1/25 (4.0%) for confirmed and suspected cases. This outbreak, with the largest number of confirmed cases ever described in CAR, confirms the potential severity of the disease associated with clade I monkeypox viruses, and highlights the need for rapid control over virus circulation to prevent the further national and international spread of infection.

Abstract
BACKGROUND In 2022, there were outbreaks of Mpox where the disease is not endemic. We summarised and compared the findings from published observational studies on the clinical presentation and epidemiology of the 2022 and previous outbreaks of Mpox. METHODS We registered a review protocol with the Open Science Framework (osf.io/j3kb7). We searched MEDLINE, Embase, CENTRAL, CINAHL and Scopus databases, and relevant websites up to August 30, 2022. Retrieved literature citations were screened for eligibility, and summary clinical presentation and epidemiological data from the included studies were pooled, when possible, using an inverse variance, random-effects model. RESULTS Seventy-nine studies met the eligibility. Irrespective of outbreak, fever, headache, myalgia, lymphadenopathy, pleomorphic skin lesions, oral lesions, and sore throat were potentially highly relevant Mpox manifestations, while conjunctivitis, cough, and possibly reactivation of varicella zoster virus may be part of the clinical presentation. The mean incubation period for the 2022 outbreaks was 7.4 d (6.4-8.4 d, I2 64.2%; 4 studies: 270 cases) and for previous outbreaks, 12.9 d (10.4-15.5 d; one study: 31 cases), p < .001. None of the male cases from previous outbreaks was reported to have sex with men (MSM) whereas almost all reported male cases from the 2022 outbreak were MSM. Concomitant sexually transmitted infections and perianal lesions were reported only among male cases from the 2022 outbreak, with the cases mostly presenting with genital lesions. CONCLUSIONS The 2022 Mpox outbreaks appear to be mostly among MSM and have a lower incubation period compared with previous outbreaks.Key messages79 studies met the review's inclusion criteria.The 2022 Mpox outbreaks appear to have shorter incubation period compared with previous outbreaks.Established clinical presentation of Mpox includes fever, headache, myalgia, lymphadenopathy, pleomorphic skin lesions, oral lesions, and sore throat.Almost all reported cases from the 2022 Mpox outbreaks were men who had sex with men (MSM).Concomitant sexually transmitted infections and perianal lesions were only reported among cases from the 2022 Mpox outbreaks.A significantly higher proportion of Mpox cases from the 2022 outbreaks had genital lesions compared with cases from previous outbreaks.The 2022 Mpox outbreaks appear to be mostly among MSM.

Abstract
Monkeypox is a zoonotic virus that has recently affected different countries worldwide. On July 23, 2022, the WHO declared the outbreak of monkeypox as a public health emergency of international concern. Surveillance studies conducted in Central Africa in the 1980s and later during outbreaks in the same region showed smallpox vaccines to be clinically somewhat effective against Monkeypox virus. However, there is no specific vaccine against this virus. This research used bioinformatics techniques to establish a novel multi-epitope vaccine candidate against Monkeypox that can induce a strong immune response. Five well-known antigenic proteins (E8L, A30L, A35R, A29L, and B21R) of the virus were picked and assessed as possible immunogenic peptides. Two suitable peptide candidates were selected according to bio-informatics analysis. Based upon in silico evaluation, two multi-epitope vaccine candidates (ALALAR and ALAL) were built with rich-epitope domains consisting of high-ranking T and B-cell epitopes. After predicting and evaluating the 3D structure of the protein candidates, the most efficient 3D models were considered for docking studies with Toll-like receptor 4 (TLR4) and the HLA-A * 11:01, HLA-A*01:01, HLA-A*02:01, HLA-A*03:01, HLA-A*07:02, HLA-A*15:01, HLA-A*30:01 receptors. Subsequently, molecular dynamics (MD) simulation of up to 150 nanoseconds was employed to assess the durability of the interaction of the vaccine candidates with immune receptors. MD studies showed that M5-HLA-A*11:01, ALAL-TLR4, and ALALAR-TLR4 complexes were stable during simulation. Analysis of the in silico outcomes indicates that the M5 peptide and ALAL and ALALAR proteins may be suitable vaccine candidates against the Monkeypox virus.Communicated by Ramaswamy H. Sarma.

Abstract
Mpox, formerly called monkeypox, is now the most serious orthopoxvirus (OPXV) infection in humans. This zoonotic disease has been gradually re-emerging in humans with an increasing frequency of cases found in endemic areas, as well as an escalating frequency and size of epidemics outside of endemic areas in Africa. Currently, the largest known mpox epidemic is spreading throughout the world, with over 85,650 cases to date, mostly in Europe and North America. These increased endemic cases and epidemics are likely driven primarily by decreasing global immunity to OPXVs, along with other possible causes. The current unprecedented global outbreak of mpox has demonstrated higher numbers of human cases and greater human-to-human transmission than previously documented, necessitating an urgent need to better understand this disease in humans and animals. Monkeypox virus (MPXV) infections in animals, both naturally occurring and experimental, have provided critical information about the routes of transmission; the viral pathogenicity factors; the methods of control, such as vaccination and antivirals; the disease ecology in reservoir host species; and the conservation impacts on wildlife species. This review briefly described the epidemiology and transmission of MPXV between animals and humans and summarizes past studies on the ecology of MPXV in wild animals and experimental studies in captive animal models, with a focus on how animal infections have informed knowledge concerning various aspects of this pathogen. Knowledge gaps were highlighted in areas where future research, both in captive and free-ranging animals, could inform efforts to understand and control this disease in both humans and animals.

Abstract
(1) Background: In early May 2022, an increasing number of human monkeypox (mpox) cases were reported in non-endemic disparate regions of the world, which raised concerns. Here, we provide a systematic review and meta-analysis of mpox-confirmed patients presented in peer-reviewed publications over the 10 years before and during the 2022 outbreak from demographic, epidemiological, and clinical perspectives. (2) Methods: A systematic search was performed for relevant studies published in Pubmed/Medline, Embase, Scopus, and Google Scholar from 1 January 2012 up to 15 February 2023. Pooled frequencies with 95% confidence intervals (CIs) were assessed using the random or fixed effect model due to the estimated heterogeneity of the true effect sizes. (3) Results: Out of 10,163 articles, 67 met the inclusion criteria, and 31 cross-sectional studies were included for meta-analysis. Animal-to-human transmission was dominant in pre-2022 cases (61.64%), but almost all post-2022 reported cases had a history of human contact, especially sexual contact. The pooled frequency of MSM individuals was 93.5% (95% CI 91.0-95.4, I2: 86.60%) and was reported only in post-2022 included studies. The male gender was predominant in both pre- and post-2022 outbreaks, and the mean age of confirmed cases was 29.92 years (5.77-41, SD: 9.38). The most common clinical manifestations were rash, fever, lymphadenopathy, and malaise/fatigue. Proctalgia/proctitis (16.6%, 95% CI 10.3-25.6, I2: 97.76) and anal/perianal lesions (39.8%, 95% CI 30.4-49.9, I2: 98.10) were the unprecedented clinical manifestations during the 2022 outbreak, which were not described before. Genitalia involvement was more common in post-2022 mpox patients (55.6%, 95% CI 51.7-59.4, I2: 88.11). (4) Conclusions: There are speculations about the possibility of changes in the pathogenic properties of the virus. It seems that post-2022 mpox cases experience a milder disease with fewer rashes and lower mortality rates. Moreover, the vast majority of post-2022 cases are managed on an outpatient basis. Our study could serve as a basis for ongoing investigations to identify the different aspects of previous mpox outbreaks and compare them with the current ones.

Global Epidemiological Features of Human Monkeypox Cases and Their Associations With Social-Economic Level and International Travel Arrivals: A Systematic Review and Ecological Study. Int J Public Health 2023; 68:1605426. [PMID: 36743344 PMCID: PMC9894882 DOI: 10.3389/ijph.2023.1605426] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Accepted: 01/12/2023] [Indexed: 01/22/2023] Open
Abstract
Objectives: We aimed to evaluate global epidemiological features of human monkeypox (mpox) cases and their associations with social-economic level and international travel arrivals. Methods: We estimated the pooled value by random-effects models. Then, we conducted an ecological study to evaluate the relationship of confirmed cases with social-economic indices and international travel arrivals using correlation analyses. Results: The average age (2022: 35.52, 95% CI [28.09, 42.94] vs. before 2022: 18.38, 95% CI [14.74, 22.02]) and comorbidity rate (2022: 15.7%, 95% CI [8.9%, 22.4%] vs. before 2022: 14.9%, 95% CI [8.5%, 21.3%]) of mpox cases in the 2022 human mpox outbreak were significantly higher than those of cases before 2022. During the 2022 mpox outbreak, the proportion of men who have sex with men (MSM) was high (79.8%, 95% CI [65.5%, 94.2%]). The number of confirmed mpox cases in 2022 significantly correlated with high social-economic levels and international travel arrivals (all p < 0.05). Conclusion: Our findings highlighted the importance of early surveillance and timely detection in high-risk populations, including older people, MSM, and travelers, which is crucial to curb the wide transmission of mpox.

Abstract
We analyzed monkeypox disease surveillance in Central African Republic (CAR) during 2001-2021. Surveillance data show 95 suspected outbreaks, 40 of which were confirmed as monkeypox, comprising 99 confirmed and 61 suspected monkeypox cases. After 2018, CAR's annual rate of confirmed outbreaks increased, and 65% of outbreaks occurred in 2 forested regions bordering the Democratic Republic of the Congo. The median patient age for confirmed cases was 15.5 years. The overall case-fatality ratio was 7.5% (12/160) for confirmed and suspected cases, 9.6% (8/83) for children <16 years of age. Decreasing cross-protective immunity from smallpox vaccination and recent ecologic alterations likely contribute to increased monkeypox outbreaks in Central Africa. High fatality rates associated with monkeypox virus clade I also are a local and international concern. Ongoing investigations of zoonotic sources and environmental changes that increase human exposure could inform practices to prevent monkeypox expansion into local communities and beyond endemic areas.

Abstract
BACKGROUND On 7th May 2022, human monkeypox was identified in the United Kingdom, a non-endemic zone, with subsequent multi-country outbreaks. About 6 weeks later, the European Centre for Disease Prevention and Control reported 1158 confirmed cases in non-endemic countries scattered within the European Economic Area (EEA), and a total of 1882 cases confirmed worldwide, inclusive of the EEA. These numbers are expected to increase with high alert and amplified surveillance established in non-endemic regions. In light of a looming epidemic, current understanding of the virus, and identification of gaps in the literature remain critical hence warranting a scoping review of available literature. METHODS Literature searches were performed through PubMed, SCOPUS, ScienceDirect and Hinari to identify studies eligible for inclusion in accordance with PRISMA guidelines. RESULTS Seventy-seven articles were included in the review. Majority of the cases were from the Central African clade (n = 29,905) versus the West African clade (n = 252). 6/16 articles that reported vaccination status stated that none of the cases were vaccinated. In the remaining articles, approximately 80%-96% cases were unvaccinated. It was noted that 4%-21% of the vaccinated individuals got infected. The secondary attack rate ranged from 0% to 10.2%, while the calculated pooled estimated case fatality rate was 8.7%. CONCLUSION This scoping review provides an extensive look at our current understanding on monkeypox disease. Further studies are needed to better understand its risk factors, genetics and natural history, in order for public health strategists to generate prevention strategies and management decisions.

Abstract
Monkeypox is an emerging infectious disease, which has a clinical presentation similar to smallpox. In the two past decades, Central Africa has seen an increase in the frequency of cases, with many monkeypox virus (MPXV) isolates detected in the Democratic Republic of Congo (DRC) and the Central African Republic (CAR). To date, no complete MPXV viral genome has been published from the human cases identified in the CAR. The objective of this study was to sequence the full genome of 10 MPXV isolates collected during the CAR epidemics between 2001 and 2018 in order to determine their phylogenetic relationships among MPXV lineages previously described in Central Africa and West Africa. Our phylogenetic results indicate that the 10 CAR isolates belong to three lineages closely related to those found in DRC. The phylogenetic pattern shows that all of them emerged in the rainforest block of the Congo Basin. Since most human index cases in CAR occurred at the northern edge of western and eastern rainforests, transmissions from wild animals living in the rainforest is the most probable hypothesis. In addition, molecular dating estimates suggest that periods of intense political instability resulting in population movements within the country often associated also with increased poverty may have led to more frequent contact with host wild animals. The CAR socio-economic situation, armed conflicts and ecological disturbances will likely incite populations to interact more and more with wild animals and thus increase the risk of zoonotic spillover.

Abstract
BACKGROUND Monkeypox is a poorly described emerging zoonosis endemic to Central and Western Africa. METHODS Using surveillance data from Tshuapa Province, Democratic Republic of the Congo during 2011-2015, we evaluated differences in incidence, exposures, and clinical presentation of polymerase chain reaction-confirmed cases by sex and age. RESULTS We report 1057 confirmed cases. The average annual incidence was 14.1 per 100 000 (95% confidence interval, 13.3-15.0). The incidence was higher in male patients (incidence rate ratio comparing males to females, 1.21; 95% confidence interval, 1.07-1.37), except among those 20-29 years old (0.70; .51-.95). Females aged 20-29 years also reported a high frequency of exposures (26.2%) to people with monkeypox-like symptoms.The highest incidence was among 10-19-year-old males, the cohort reporting the highest proportion of animal exposures (37.5%). The incidence was lower among those presumed to have received smallpox vaccination than among those presumed unvaccinated. No differences were observed by age group in lesion count or lesion severity score. CONCLUSIONS Monkeypox incidence was twice that reported during 1980-1985, an increase possibly linked to declining immunity provided by smallpox vaccination. The high proportion of cases attributed to human exposures suggests changing exposure patterns. Cases were distributed across age and sex, suggesting frequent exposures that follow sociocultural norms.
