Atypical Mpox in a Nigerian Tertiary Health Facility. J Infect Dis 2024; 229:S181-S187. [PMID: 38157416 DOI: 10.1093/infdis/jiad607] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Revised: 12/22/2023] [Accepted: 12/26/2023] [Indexed: 01/03/2024] Open
Abstract
BACKGROUND We describe diverse clinical characteristics and course of confirmed mpox cases managed in a Nigerian tertiary health facility. METHODS Clinical and epidemiologic data were analyzed, highlighting the unusual presentations of polymerase chain reaction (PCR)-confirmed mpox cases observed during the 2022 outbreak. RESULTS Out of 17 suspected cases, 13 (76.4%) were PCR confirmed for mpox. The mean ± SD age for the participants was 28.62 ± 10.29 years (range, 2-55), of which 9 (64.3%) were male. Of the 13 PCR-confirmed cases, 5 (38.5%) had varicella zoster virus coinfection, 2 (15.4%) had HIV coinfection, and 1 (7.7%) had diabetes mellitus comorbidity. All patients experienced rash, with 6 (46.2%) having significant genital lesions and 1 (7.7%) having a severe perianal lesion. A lack of prodromal symptoms was reported in 3 (23.1%), and a prolonged prodrome (>1 week) occurred in 5 (38.5%). Skin lesions were polymorphic in 6 (46.2%), and solitary skin lesions occurred in 3 (23.1%), which persisted for >120 days in 7.7%. CONCLUSIONS Clinical recognition, diagnosis, and prevention remain a concern in resource-limited settings. Our findings highlight the need to further evaluate unusual skin lesions and to include mpox screening for genital skin lesions that are presumed to be sexually transmitted infections. Revision of clinical case definition and enhanced surveillance are key to early recognition and prevention of spread.

Abstract
Monkeypox virus (MPXV) is the etiological agent of monkeypox (mpox), a zoonotic disease. MPXV is endemic in the forested regions of West and Central Africa, but the virus has recently spread globally, causing outbreaks in multiple non-endemic countries. In this paper, we review the characteristics of the virus, including its ecology, genomics, infection biology, and evolution. We estimate by phylogenomic molecular clock that the B.1 lineage responsible for the 2022 mpox outbreaks has been in circulation since 2016. We interrogate the host-virus interactions that modulate the virus infection biology, signal transduction, pathogenesis, and host immune responses. We highlight the changing pathophysiology and epidemiology of MPXV and summarize recent advances in the prevention and treatment of mpox. In addition, this review identifies knowledge gaps with respect to the virus and the disease, suggests future research directions to address the knowledge gaps, and proposes a One Health approach as an effective strategy to prevent current and future epidemics of mpox.

Abstract
Monkeypox virus belongs to the genus Orthopoxvirus There was a worldwide mpox outbreak in 2022, with many cases reported in Europe in gay, bisexual and other men who have sex with men. Here, we report a case of mpox diagnosed in a heterosexual woman in her twenties without any known history of exposure. This is a very rare event. Despite lesions remaining for more than 1 month, she recovered fully with no sequelae. We highlight the diagnosis of mpox in a heterosexual woman without a known or suspected history of exposure or any risk factor for acquiring the infection.

Abstract
Starting from May 31, 2023, the local transmission of monkeypox (Mpox) in mainland China began in Beijing. Till now, the transmission characteristics have not been explored. Based on the daily Mpox incidence data in the first 3 weeks of Beijing (from May 31 to June 21, 2023), we employed the instant-individual heterogeneity transmission model to simultaneously calculate the effective reproduction number (Re ) and the degree of heterogeneity (k) of the Beijing epidemic. We additionally simulated the monthly infection size in Beijing from July to November and compared with the reported data to project subsequent transmission dynamics. We estimated Re to be 1.68 (95% highest posterior density [HPD]: 1.12-2.41), and k to be 2.57 [95% HPD: 0.54-83.88], suggesting the transmission of Mpox in Beijing was supercritical and didn't have considerable transmission heterogeneity. We projected that Re fell in the range of 0.95-1.0 from July to November, highlighting more efforts needed to further reduce the Mpox transmissibility. Our findings revealed supercritical and homogeneous transmission of the Mpox epidemic in Beijing. Our results could serve as a reference for understanding and predicting the ongoing Mpox transmission in other regions of China and evaluating the effect of control measures.

Intention to receive the monkeypox vaccine and its psychological and sociodemographic predictors: a cross-sectional survey in the general population of Peru.

Abstract
OBJECTIVE The objective of this study was to identify predictors of intention to be vaccinated against Monkeypox (Mpox) in a sample of Peruvian citizens. METHODS: A set of sociodemographic and psychological predictors were used, such as sex, sexual orientation, educational level, previous diagnosis of COVID-19, marital status, complete vaccination against COVID-19, employment status, living with vulnerable people, presence of chronic disease, area of residence, perceived usefulness of COVID-19 vaccines, fear of Mpox, conspiracy beliefs about Mpox, among others. A total of 472 Peruvian adults participated, selected by non-probabilistic snowball convenience sampling. A sociodemographic survey, the Mpox Fear Scale, was used. Conspiracy Beliefs about Mpox was assessed using three questions created specifically for this study. For inferential purposes, simple ordinal regressions ("crude models") were performed between each factor and the outcome. RESULTS: Regarding their intention to be vaccinated against Mpox, more than 60% expressed clear approval. Being non-heterosexual, having greater emotional fear of Mpox, and perceiving some potential for this disease to become the next pandemic were related to greater intention to vaccinate. On the other hand, being older, having low perceived usefulness of COVID-19 vaccines, and having higher conspiracy beliefs about Mpox were associated with lower intention to vaccinate. CONCLUSION: The study provides initial information for future research seeking to better analyze Mpox vaccination intention. In addition, cross-sectional data are provided that can be used to develop public health policies that target subgroups with low prevalence of intention to vaccinate against Mpox.

Monkeypox: a review of epidemiological modelling studies and how modelling has led to mechanistic insight. Epidemiol Infect 2023; 151:e121.

Abstract
Human monkeypox (mpox) virus is a viral zoonosis that belongs to the Orthopoxvirus genus of the Poxviridae family, which presents with similar symptoms as those seen in human smallpox patients. Mpox is an increasing concern globally, with over 80,000 cases in non-endemic countries as of December 2022. In this review, we provide a brief history and ecology of mpox, its basic virology, and the key differences in mpox viral fitness traits before and after 2022. We summarize and critique current knowledge from epidemiological mathematical models, within-host models, and between-host transmission models using the One Health approach, where we distinguish between models that focus on immunity from vaccination, geography, climatic variables, as well as animal models. We report various epidemiological parameters, such as the reproduction number, R0, in a condensed format to facilitate comparison between studies. We focus on how mathematical modelling studies have led to novel mechanistic insight into mpox transmission and pathogenesis. As mpox is predicted to lead to further infection peaks in many historically non-endemic countries, mathematical modelling studies of mpox can provide rapid actionable insights into viral dynamics to guide public health measures and mitigation strategies.

Virtual screening and computational simulation analysis of antimicrobial photodynamic therapy using propolis-benzofuran A to control of Monkeypox. Photodiagnosis Photodyn Ther 2023; 41:103208. [PMID: 36417972 PMCID: PMC9675939 DOI: 10.1016/j.pdpdt.2022.103208] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Revised: 11/05/2022] [Accepted: 11/18/2022] [Indexed: 11/21/2022]
Abstract
BACKGROUND Monkeypox is a viral zoonotic disease and there are no available treatments that specifically target the monkeypox virus. Antimicrobial photodynamic therapy (aPDT) is a non-invasive approach that has been introduced as a targeted adjuvant treatment against various microbial infections. In this study, we used a computational strategy to investigate the potential of aPDT using propolis-benzofuran A against the Monkeypox virus. METHODS In this in silico study, the evaluation of drug-likeness, molecular properties, and bioactivity of propolis-benzofuran A was carried out using SwissADME. Pro-Tox II and OSIRIS servers were used to identify the organ toxicities and toxicological endpoints of propolis-benzofuran A. Molecular docking approach was employed to screen the potential binding modes of propolis-benzofuran A ligand with the Monkeypox virus A48R protein (PDB ID: 2V54). RESULTS The results of the computational investigation revealed that propolis-benzofuran A obeyed all the criteria of Lipinski's rule of five and exhibited drug-likeness. The photosensitizing agent tested was categorized as toxicity class-5 and was found to be non-hepatotoxic, non-carcinogenic, non-mutagenic, and non-cytotoxic. The docking studies employing a predicted three-dimensional model of Monkeypox virus A48R protein with propolis-benzofuran A ligand exhibited good binding affinity (-7.84 kcal/mol). DISCUSSION The computational simulation revealed that propolis-benzofuran A had a strong binding affinity with the Monkeypox virus A48R protein. Hence, aPDT based on this natural photosensitizer can be proposed as an adjuvant treatment against the Monkeypox virus.

Abstract
Viral infections attract more and more attention, especially after the emergence of novel zoonotic coronaviruses and the monkeypox virus over the last 2 decades. Research on viruses is based to a great extent on mammalian cell lines that are permissive to the respective viruses. These cell lines are usually cultivated according to the protocols established in the 1950s to 1970s, although it is clear that classical media have a significant imprint on cell growth, phenotype, and especially metabolism. So, recently in the field of biochemistry and metabolomics novel culture media have been developed that resemble human blood plasma. As perturbations in metabolic and redox pathways during infection are considered significant factors of viral pathogenesis, these novel medium formulations should be adapted by the virology field. So far, there are only scarce data available on viral propagation efficiencies in cells cultivated in plasma-like media. But several groups have presented convincing data on the use of such media for cultivation of uninfected cells. The aim of the present review is to summarize the current state of research in the field of plasma-resembling culture media and to point out the influence of media on various cellular processes in uninfected cells that may play important roles in viral replication and pathogenesis in order to sensitize virology research to the use of such media.

Abstract
The recent increase in monkeypox (MPX) cases has attracted attention of public health authorities due to its quick spread and transmission across non-endemic regions. This outbreak, unlike previous ones, displays different epidemiological features and transmission dynamics, which appear to be largely influenced by the newly divergent MPX lineages (B.1). Yet, the genomic characteristics driving the high dispersal and diversification of these lineages remain largely unknown. Herein, we sought to explore and characterize the genomic features and phylogenetic diversity of the B.1 lineages through a comparative genomic analysis inclusive of 1900 high quality complete MPXV genomes. Our analyses indicate that the current MPXV-2022 outbreak encompasses thirteen derived lineages with ten unique non-synonymous mutations in several genes linked to immune evasion, virulence factors and host recognition. Such mutations may translate in the rapid evolution and diversification of current MPXV lineages. Moreover, our analyses uncovered signals of genomic modifications suggestive of immune-modulatory enzymatic activity, such as APOBEC3 editing, which, as previously suggested could have favored evolutionary trends leading to the rapid spread of MPXV into non-endemic countries. Genomic surveillance continues to play a major role in unveiling the genomic signatures signaling potential adaptation of this emerging MPXV lineage and how it will continue to impact public health in the near future.

Abstract
BACKGROUND Public awareness of monkeypox is critical in the fight against this infectious disease. However, at present a survey of the Chinese population on monkeypox is lacking. This study was conducted to compensate for the lack of knowledge and identify a vaccination intention assessment for monkeypox in China. METHODS The questionnaire comprised 20 items with the following three aspects: basic information, knowledge, and willingness to vaccinate or pay. For this study, 521 valid respondents were recruited. Utilizing logistic regression, the researchers identified the factors related with knowledge and vaccination intentions. RESULTS The average total score for knowledge of monkeypox was 5.6 (score range 0-10), and 309 (59.3%) participants were categorized as having greater knowledge based on a total score of 6. Most participants (76.4%) were willing to accept a monkeypox vaccination. The average acceptable cost of the monkeypox vaccine was CNY261.2. Factors such as level of education, and working within the healthcare profession were related to monkeypox knowledge. An increased knowledge of monkeypox was related to a higher willingness to vaccinate. Participants who were willing to pay more for vaccines included those with high incomes, who suffered from chronic diseases, and healthcare workers. CONCLUSIONS The Chinese population had relatively high knowledge of monkeypox and demonstrated a willingness to receive the vaccine.

Abstract
Monkeypox, a viral zoonosis caused by an Orthopoxvirus, is clinically characterized by fever, headache, lymphadenopathy, myalgia, rash and burdened by some complications that can be severe and life threatening. Monkeypox, endemic in some central and west African countries, in tropical areas near equator, rose to the headlines following its recent outbreak in non-endemic countries of Europe and the USA. Thus, the World Health Organization, worried about the growing dimension of the problem, declared monkeypox a global public health emergency. Now, after months of careful observation, the western scientific research is drawing conclusion that African endemic countries represent a reserve pool able to feed, through travelers and sexual networks, the outbreak in non-endemic countries in which high-risk communities such as gay and bisexual men are the most affected. Prevention through vaccination and early diagnosis are the core to breaking the chain of diffusion of this epidemic. Particular attention should be paid to avoid the spread from endemic countries, also implementing the economic investments in their public health system. Information campaigns and assistance to high-risk classes in non-endemic countries are important priorities, however, assuming that specific treatments for this disease are still tentative.

Johri N, Kumar D, Nagar P, Maurya A, Vengat M, Jain P. Clinical manifestations of human monkeypox infection and implications for outbreak strategy. HEALTH SCIENCES REVIEW (OXFORD, ENGLAND) 2022; 5:100055. [PMID: 36254190 PMCID: PMC9535997 DOI: 10.1016/j.hsr.2022.100055] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Revised: 09/08/2022] [Accepted: 10/02/2022] [Indexed: 11/09/2022]
Abstract
Monkeypox is an orthopoxvirus-based zoonotic illness that causes symptoms similar to smallpox in humans. Health care workers around the world are making it a priority to educate themselves on the many clinical manifestations and treatment options for this virus as public health agencies strive to stop the current outbreak. The infected do not have access to any treatment at this time. However, information obtained from the smallpox pandemic has led researchers to examine vaccinia immune globulin (IVG), tecovirimat, and cidofovir as viable treatments for monkeypox. Moreover, medication like tecovirimat may be given in extreme circumstances, and supportive therapy can help with symptom relief. The European Medicines Agency (EMA) certified tecovirimat as safe and effective against monkeypox in 2022, per the World Health Organization (WHO). As there are now no established guidelines for alleviating these symptoms, the efficacy of these treatments is highly questionable. Some high-profile cases in recent years have cast doubt on the long-held belief that this illness is rare and always resolves itself without treatment. We aimed to conduct this review to get a deeper comprehension of the evolving epidemiology of monkeypox by analysing such factors as the number of confirmed, probable, and potential cases, the median age at presentation, the mortality rate, and the geographic distribution of the disease. This study offers an updated review of monkeypox and the clinical treatments that are currently available as a result of the worldwide epidemics.
