Abstract
Some evidence has indicated that monkeypox can induce a cytokine storm. Purinergic signaling is a cell pathway related to the cytokine storm. However, the precise mechanisms that lead to cytokine storms in monkeypox infections and the possible involvement of purinergic signaling in the immune response to this virus remain unknown. In this review article, we aimed to highlight a body of scientific evidence that consolidates the role of the cytokine storm in monkeypox infection and proposes a new hypothesis regarding the roles of purinergic signaling in this immune-mediated mechanism. We further suggested some purinergic signaling modulators to mitigate the deleterious and aggravating effects of immune dysregulation in human monkeypox virus infection by inhibiting P2X3, P2X7, P2Y2, and P2Y12, reducing inflammation, and activating A1 and A2A receptors to promote an anti-inflammatory response.

Abstract
Monkeypox (MPX) is a viral zoonotic disease that is endemic in Central and West African countries had affected countries in Asia, Europe, Africa, Australia, and South and North America. Some globally reported cases were linked to history of recent travel to endemic regions, however, official reports revealed homosexual practices among the majority of reported cases. In response to global increase MPX burden and number of cases, the WHO declared MPX a Public Health Emergency with International Concern (PHEIC) on July 23, 2022. The first MPX case in Saudi Arabia was a returning traveler from Europe to Riyadh on July 14, 2022. It is essential for policy makers to maintain neutral tone for health education messages and inform the public that MPX transmits via physical contact.

Abstract
BACKGROUND Very few studies have investigated the effectiveness of vaccination in decreasing the severity of breakthrough mpox. Our goal was to estimate the strength of the associations between recent mpox vaccination with MVA-BN and various clinical manifestations of the disease. METHODS Telephone interviews using standardized questionnaires, upon notification and 28 days later, of the 403 persons with mpox reported to Montreal Public Health in 2022. MVA-BN vaccination data were obtained from the provincial immunization registry. The main outcomes were numbers of skin lesions and body sites affected, other clinical manifestations (OCM) compatible with mpox, complications, and hospitalization. FINDINGS 155 persons with mpox (39% of 403) had received 1 dose of vaccine at least 14 days before symptom onset. One-dose vaccination, adjusting for age and HIV status, was significantly associated with fewer lesions, sites affected with lesions, and OCMs. HIV-positive persons with breakthrough mpox reported significantly more lesions, sites affected, and OCMs at initial interview, than HIV-negative ones. However, vaccination was associated with a lower risk of all outcomes to the same degree irrespective of HIV status. INTERPRETATION One dose of MVA-BN vaccine was about 60% effective in decreasing the frequency and extent of clinical manifestations, among both HIV-positive and HIV-negative persons with breakthrough mpox. Beyond preventing infection, mpox vaccination can be promoted to reduce clinical manifestations in persons at risk for mpox, even if HIV+ . FUNDING This work used data obtained as part of Montreal Public Health's 2022 mpox outbreak response and received no external funding.

Abstract
The Human monkeypox virus (mpox) belongs to the Poxviridae family, characterized by double-stranded DNA. A 2022 outbreak, notably prevalent among men who have sex with men, was confirmed by the World Health Organization. To understand shifting prevalence patterns and clinical manifestations, we conducted a systematic review of recent animal and human studies. We comprehensively searched PubMed, Scopus, Web of Science, Cochrane Library, and Clinicaltrials.gov, reviewing 69 relevant articles from 4,342 screened records. Our analysis highlights Modified Vaccinia Ankara - Bavarian Nordic (MVA-BN)'s potential, though efficacy concerns exist. Tecovirimat emerged as a prominent antiviral in the recent outbreak. However, limited evidence underscores the imperative for further clinical trials in understanding and managing monkeypox.

Abstract
Brazil ranked third in the number of Monkeypox infected worldwide in early September 2022 and eighth in multiple deaths. Brazilian Ministry of Health prepared a public policy to face the smallpox outbreak. This paper aims to analyze the governmental public policy' impacts on Monkeypox using survival analysis. The information in the database was collected from epidemiological bulletins on the official websites of the Brazilian Ministry of Health and the World Health Organization (WHO). The survival analysis with parametric statistical analysis, semiparametric with Cox regression, and nonparametric analysis were used. The inference of causality was perceived by the impact caused by the national public policy with the proportional reduction in the number of cases in the treatment group (Chi-sq = 117.783, p < 0.001), contrary to what was perceived in the control group, as well as survival about the time of the states that elaborated their plans based on what was made available by the government. The need to evaluate government projects should be within the scope of project management in Brazilian states and provide for more assertive decision-making in the fight against smallpox.

Abstract
INTRODUCTION During the 2022 outbreak of mpox (previously called monkeypox), which primarily affected Gay, Bisexual, and other Men who have Sex with Men (GBMSM), testing was mainly limited to individuals with symptoms of infection. Although sporadic cases of mpox continue to be diagnosed in Denmark, the feasibility of screening asymptomatic high-risk populations, such as those using HIV pre-exposure prophylaxis (PrEP), is still unknown. METHODS During the autumn of 2022, a rectal swab test for mpox PCR was included in the routine sexually transmitted infections (STI) screening for PrEP users. RESULTS The screening included 224 asymptomatic men with a median age of 36.5 years. One patient (0.4%) tested positive for mpox. Ten (4.5%) and nine (4.0%) had chlamydia and gonorrhea, respectively. DISCUSSION Our study demonstrates that screening for mpox is feasible in two Danish PrEP clinics.

Abstract
Recent years have witnessed the rise of more recent pandemic outbreaks including COVID-19 and monkeypox. A multinational monkeypox outbreak creates a complex situation that necessitates countermeasures to the existing quo. The first incidence of monkeypox was documented in the 1970s, and further outbreaks led to a public health emergency of international concern. Yet as of right now, neither vaccines nor medicines are certain to treat monkeypox. Even the inability of conducting human clinical trials has prevented thousands of patients from receiving effective disease management. The current state of the disease's understanding, the treatment options available, financial resources, and lastly international policies to control an epidemic state are the major obstacles to controlling epidemics. The current review focuses on the epidemiology of monkeypox, scientific ideas, and available treatments, including potential monkeypox therapeutic methods. As a result, a thorough understanding of monkeypox literature will facilitate in the development of new therapeutic medications for the prevention and treatment of monkeypox.

Abstract
The 2022 multi-country Monkeypox (Mpox) outbreak has added concerns to scientific research. However, unanswered questions about the disease remain. These unanswered questions lie in different aspects, such as transmission, the affected community, clinical presentations, infection and prevention control and treatment and vaccination. It is imperative to address these issues to stop the spread and transmission of disease. We documented unanswered questions with Mpox and offered suggestions that could help put health policy into practice. One of those questions is why gay, bisexual or other men who have sex with men (gbMSM) are the most affected community, underscoring the importance of prioritizing this community regarding treatment, vaccination and post-exposure prophylaxis. In addition, destigmatizing gbMSM and implementing community-based gbMSM consultation and action alongside ethical surveillance can facilitate other preventive measures such as ring vaccination to curb disease transmission and track vaccine efficacy. Relevant to that, vaccine and drug side effects have implied the questionability of their use and stimulated the importance of health policy development regarding expanded access and off-label use, expressing the need for safe drug and vaccine development manufacturing. The possibility of reverse zoonotic has also been raised, thus indicating the requirement to screen not only humans, but also their related animals to understand the real magnitude of reverse zoonosis and its potential risks. Implementing infection prevention and control measures to stop the virus circulation at the human-animal interface that includes One Health approach is essential.

Abstract
This work concerns the epidemiology of infectious diseases like monkeypox (mpox) in humans and animals. Our models examine transmission scenarios, including transmission dynamics between humans, animals, and both. We approach this using evolutionary game theory, specifically the intervention game-theoretical (IGT) framework, to study how human behavior can mitigate disease transmission without perfect vaccines and treatments. To do this, we use non-pharmaceutical intervention, namely the quarantine policy, which demonstrates the delayed effect of the epidemic. Additionally, we contemplate quarantine-based behavioral intervention policies in deterministic and fractional-order models to show behavioral impact in the context of the memory effect. Firstly, we extensively analyzed the model's positivity and boundness of the solution, reproduction number, disease-free and endemic equilibrium, possible stability, existence, concavity, and Ulam-Hyers stability for the fractional order. Subsequently, we proceeded to present a numerical analysis that effectively illustrates the repercussions of varying quarantine-related factors, information probability, and protection probability. We aimed to comprehensively examine the effects of non-pharmaceutical interventions on disease control, which we conveyed through line graphs and 2D heat maps. Our findings underscored the significant influence of strict quarantine measures and the protection of both humans and animals in mitigating disease outbreaks. These measures not only significantly curtailed the spread of the disease but also delayed the occurrence of the epidemic's peak. Conversely, when quarantine maintenance policies were implemented at lower rates and protection levels diminished, we observed contrasting outcomes that exacerbated the situation. Eventually, our analysis revealed the emergence of animal reservoirs in cases involving disease transmission between humans and animals.

Abstract
BACKGROUND Cases of mpox have been reported worldwide since May 2022. Limited knowledge exists regarding the long-term course of this disease. To assess sequelae in terms of scarring and quality of life (QoL) in mpox patients 4-6 months after initial infection. METHODS Prospective observational study on clinical characteristics and symptoms of patients with polymerase chain reaction (PCR)-confirmed mpox, including both outpatients and inpatients. Follow-up visits were conducted at 4-6 months, assessing the Patient and Observer Scar Assessment Scale (POSAS), the Dermatology Life Quality Index (DLQI) and sexual impairment, using a numeric rating scale (NRS) from 0 to 10. RESULTS Forty-three patients, age range 19-64 years, 41 men (all identifying as MSM) and 2 women, were included. Upon diagnosis, skin or mucosal lesions were present in 93.0% of cases, with 73.3% reporting pain (median intensity: 8, Q1-Q3: 6-10). Anal involvement resulted in a significantly higher frequency of pain than genital lesions (RR: 3.60, 95%-CI: 1.48-8.74). Inpatient treatment due to pain, superinfection, abscess or other indications was required in 20 patients (46.5%). After 4-6 months, most patients did not have significant limitations, scars or pain. However, compared to patients without such complications, patients with superinfection or abscess during the acute phase had significantly more extensive scar formation (median PSAS: 24.0 vs. 11.0, p = 0.039) and experienced a significantly greater impairment of their QoL (median DLQI: 2.0 vs. 0.0, p = 0.036) and sexuality (median NRS: 5.0 vs. 0.0, p = 0.017). CONCLUSION We observed a wide range of clinical mpox manifestations, with some patients experiencing significant pain and requiring hospitalization. After 4-6 months, most patients recovered without significant sequelae, but those with abscesses or superinfections during the initial infection experienced a significant reduction in QoL and sexuality. Adequate treatment, including antiseptic and antibiotic therapy during the acute phase, may help prevent such complications, and hence, improve long-term outcomes.

Abstract
The monkeypox (Mpox) virus has raised significant concerns given its recent spread with an increasing number of confirmed cases worldwide. In this study, we evaluated the performance of a laboratory developed test (LDT) using BioGX Xfree hMPXV/OPXV reagents for the qualitative detection of non-variola Orthopoxviruses and Mpox virus DNA, in swabs from human pustular or vesicular rash specimens. Analytical and clinical testing analysis were carried out on two different platforms: the BD MAX™ System (BD Diagnostics) and the new pixl.16 Real-Time PCR Platform (BioGX), using a synthetic Mpox virus DNA (ATCC VR-3270SD) and residual clinical samples previously identified with an EUA approved Mpox real-time PCR assay. In the end, the Xfree hMPXV/OPXV LDT proved to be a sensitive, specific, and reproducible test for the detection of Mpox on both platforms evaluated with the pixl.16 having an advantage of a small footprint and providing faster TAT facilitated by an extraction-free workflow.

Abstract
BACKGROUND Monkeypox is a zoonotic disease caused by the monkeypox virus and is increasingly recognized as a serious public health concern worldwide. Our aim was to investigate the knowledge and attitudes of Chinese medical students regarding monkeypox. METHODS A cross-sectional study was conducted among 8,897 college students from China. An e-questionnaire was used to collect data on knowledge (17 items), attitudes (12 items), and baseline criteria. The relationships between a range of factors and knowledge and attitudes were studied using univariate and multivariate analyses. RESULTS A total of 79.33% of the study participants were female, 89.10% were of Han ethnicity, 72.50% were from rural areas, 50.39% were in their first year, and 80.65% were medical majors. A total of 50.88% had good knowledge of monkeypox, and 57.11% had a positive attitude towards monkeypox knowledge. Univariate analysis revealed that origin and major were the factors affecting the knowledge level of monkeypox among participants. Rural students had more knowledge of monkeypox than urban students, and nonmedical students had greater awareness of monkeypox than did medical students. Moreover, sex and grade were the factors influencing participants' attitudes towards monkeypox; men had more positive attitudes than women did, and senior students had more positive attitudes than junior students did. Multivariate analysis revealed that major and the origin of the students independently influenced the monkeypox knowledge of Chinese medical students, while sex, grade and monkeypox knowledge were significantly related to attitudes towards monkeypox. CONCLUSION This study revealed that nearly half of the Chinese medical students had good knowledge and a positive attitude towards monkeypox. Student origin and major independently influenced the knowledge of Chinese medical students of monkeypox, while sex, grade and knowledge were independently related to the attitudes of Chinese medical students towards monkeypox.

Abstract
The Mpox (formerly named Monkeypox) virus is the etiological cause of a recent multi-country outbreak, with thousands of distinct cases detected outside the endemic areas of Africa as of December 2023. In this article, we analyze the sequences of full genomes of Mpox virus from Europe and compare them with all available Mpox sequences of historical relevance, annotated by year and geographic origin, as well as related Cowpox and Variola (smallpox) virus sequences. Our results show that the recent outbreak is most likely originating from the West African clade of Mpox, with >99 % sequence identity with sequences derived from historical and recent cases, dating from 1971 to 2017. We analyze specific mutations occurring in viral proteins between the current outbreak, previous Mpox and Cowpox sequences, and the historical Variola virus. Genome-wide sequence analysis of the recent outbreak and other Mpox/Cowpox/Variola viruses shows a very high conservation, with 97.9 % (protein-based) and 97.8 % (nucleotide-based) sequence identity. We identified significant correlation in human transcriptional responses as well, with a conserved immune pathway response induced in human cell cultures by the three families of Pox virus. The similarities identified between the major strains of Pox viruses, as well as within the Mpox clades, both at the genomic and transcriptomic levels, provide a molecular basis for the observed efficacy of Variola vaccines in other Poxviruses.

Abstract
INTRODUCTION Herein, we described cases of children under 16 years old suspected to be infected with Monkeypox virus (MKPV) and diagnosed with chickenpox in public hospitals of Marseille, south of France. MATERIAL AND METHODS We conducted a retrospective study from March 23rd, 2022 to October 20th, 2022 in our institution of results of MKPV DNA and varicella-zoster virus (VZV) DNA detection by PCR performed on cutaneous lesions swabs collected from children <16 years old. RESULTS None of the cutaneous swabs collected from 14 children were positive for MKPV DNA. In contrast, 30/168 (17 %) cutaneous swabs collected from children were positive for VZV DNA. Of these 30 VZV-positive children, 7 had been suspected of MKPV infection because of their atypical rash, due to the location of the lesions and the chronology of their appearance. DISCUSSION As in our cohort, pediatric cases of the 2022 Monkeypox outbreak in non-endemic developed countries have been very rare. This variant of MKPV does not normally spread easily and requires very close physical contact between an infected person (skin lesions, bodily fluids or respiratory droplets) and another person to be transmitted. It will nevertheless be a question of remaining vigilant as not to ignore the possibility of close contact or sexual transmission of Monkeypox in a child, or the possibility of a new and more contagious variant. CONCLUSION It is difficult to differentiate Monkeypox infection from other infections associated with rashes, it is important to remember that viruses change as well as their forms of presentation.

Abstract
OBJECTIVE Human monkeypox (mpox) is usually self-limited infection; however, rising data show a worse outcome in patients with impaired immune status, particularly those co-infected with HIV [Mitjà O, Alemany A, Marks M, Lezama Mora JI, Rodríguez-Aldama JC, Torres Silva MS et al. Mpox in people with advanced HIV infection: A global case series. Lancet. 2023; 401:939-49. DOI:https://doi.org/10.1016/S0140-6736(23)00273-8] [Govind A, Lazarte SM, Kitchell E, Chow JY, Estelle CD, Fixsen E et al. Severe mpox infections in people with uncontrolled human immunodeficiency virus (HIV). Clin Infect Dis. 2023; 76:1843-6. DOI:https://doi.org/10.1093/cid/ciad052]. METHODS We report the clinical, pathological, and molecular study of a patient with mpox infection and a late HIV diagnosis, with fatal outcome. RESULTS Necropsy revealed visceral spread of mpox. Mpox virus was sequenced twice during the admission, uncovering an emerging mutation near a genomic region where mutations associated with tecovirimat resistance have been documented. DISCUSSION Monkeypox can manifest as an opportunistic infection in individuals with advanced HIV-associated immunosuppression.

Abstract
The monkeypox virus (MPXV) is a zoonotic pathogen that transmits between monkeys and humans, exhibiting clinical similarities with the smallpox virus. Studies on the immunopathogenesis of MPXV revealed that an initial strong innate immune response is elicited on viral infection that subsequently helps in circumventing the host defense. Once the World Health Organization (WHO) declared it a global public health emergency in July 2022, it became essential to clearly demarcate the MPXV-induced symptoms from other viral infections. We have exhaustively searched the various databases involving Google Scholar, PubMed, and Medline to extract the information comprehensively compiled in this review. The primary focus of this review is to describe the diagnostic methods for MPXV such as polymerase chain reaction (PCR), and serological assays, along with developments in viral isolation, imaging techniques, and next-generation sequencing. These innovative technologies have the potential to greatly enhance the accuracy of diagnostic procedures. Significant discoveries involving MPXV immunopathogenesis have also been highlighted. Overall, this will be a knowledge repertoire that will be crucial for the development of efficient monitoring and control strategies in response to the MPXV infection helping clinicians and researchers in formulating healthcare strategies.

Abstract
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.

Abstract
The mucosa of the oral cavity is exposed to a large number of different microorganisms such as archaea, bacteria, fungi, parasites, and viruses. Among those, viruses cause specific infections, which can easily be transmitted from one person to another. The infectious route may not only include patients and their relatives but also the dental professional team. Thus, a wide knowledge regarding specific viral infections is crucial for the daily routine. Signs and symptoms of oral viral infections can be completely absent or develop into a pronounced clinical picture, so that early detection and information determine the further course of the infection and its influence on other inflammatory diseases, such as periodontitis, as well as the safety of family members and the social environment. As the clinical manifestation of viral infections may be highly variable leading to heterogenous mucosal lesions it is, in most cases, mandatory to differentiate them by specific microbiological tests in addition to clinical examination procedures. This article will give an overview of the role of viruses infecting the oral mucosa, and in addition, describe their clinical manifestation and management.

Abstract
BACKGROUND The 2022-2023 period marked the largest global Mpox outbreak, with Latin America's situation notably underexplored. This study aims to estimate Mpox's instantaneous reproduction number (R(t)), analyze epidemiological trends, and map vaccination efforts in six Latin American countries. METHODS Utilizing Pan American Health Organization Mpox surveillance data, we examined demographic characteristics, cumulative incidence rates, and epidemic curves, calculated R(t) with weekly sliding windows for each country, alongside a review of vaccination initiatives. RESULTS From 2022 to 2023, 25,503 Mpox cases and 71 deaths were reported across Argentina, Brazil, Chile, Colombia, Mexico and Peru, with a significant majority (91.8%-98.5%) affecting men, with a mean age of 32-35 years. Maximum R(t) values varied across countries: Argentina (2.63; 0.85 to 5.39), Brazil (3.13; 2.61 to 3.69), Chile (2.91; 1.55 to 4.70), Colombia (3.15; 2.07 to 4.44), Mexico (2.28; 1.18 to 3.75), and Peru (2.84; 2.33 to 3.40). The epidemic's peak occurred between August and September 2022 with R(t) values subsequently dropping below 1. From November 2022, and as of February 2024, only Chile, Peru, and Brazil had initiated Mpox vaccination campaigns, with Colombia launching a Clinical Trial. CONCLUSION The peak of the Mpox epidemic in the studied countries occurred before the commencement of vaccination programs. This trend may be then partly attributed to a combination of behavioral modifications in key affected communities and contact tracing local programs. Therefore, the proportion of the at-risk population that remains susceptible is still uncertain, highlighting the need for continued surveillance and evaluation of vaccination strategies.

Abstract
What is already known about this topic? The prevalence of monkeypox (mpox) infections is primarily observed among young men who engage in sexual activities with other men, and there is a possibility of sexual transmission. Co-occurring sexually transmitted infections have also been documented. What is added by this report? In this report, we present a case of a patient in China who was simultaneously diagnosed with mpox, and acute human immunodeficiency virus (HIV) infection. The patient exhibited symptoms of fever and widespread papules on the trunk, face, and genital area. What are the implications for public health practice? It is crucial for health agencies to prioritize HIV testing when mpox is suspected or diagnosed in individuals with recent engagement in high-risk sexual behavior.

Abstract
Monkeypox virus (MPXV) poses a global health emergency, necessitating rapid, simple, and accurate detection to manage its spread effectively. The Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) technique has emerged as a promising next-generation molecular diagnostic approach. Here, we developed a highly sensitive and specific CRISPR-Cas12a assisted nanopore (SCAN) with isothermal recombinase polymerase amplification (RPA) for MPXV detection. The RPA-SCAN method offers a sensitivity unachievable with unamplified SCAN while also addressing the obstacles of PCR-SCAN for point-of-care applications. We demonstrated that size-counting of single molecules enables analysis of reaction-time dependent distribution of the cleaved reporter. Our MPXV-specific RPA assay achieved a limit of detection (LoD) of 19 copies in a 50 μL reaction system. By integrating 2 μL of RPA amplifications into a 20 μL CRISPR reaction, we attained an overall LoD of 16 copies/μL (26.56 aM) of MPXV at a 95% confidence level using the SCAN sensor. We also verified the specificity of RPA-SCAN in distinguishing MPXV from cowpox virus with 100% accuracy. These findings suggest that the isothermal RPA-SCAN device is well-suited for highly sensitive and specific Monkeypox detection. Given its electronic nature and miniaturization potential, the RPA-SCAN system paves the way for diagnosing a wide array of other infectious pathogens at the point of care.

Abstract
The Monkeypox virus, an Orthopoxvirus with zoonotic origins, has been responsible for a growing number of human infections reminiscent of smallpox since May 2022, as reported by the World Health Organization. As of now, there are no established medical treatments for managing Monkeypox infections. In this study, we used machine learning to select conserved epitopes. Proteins were determined using Reverse Vaccinology and Gene Ontology subcellular localization, and their epitopes were predicted. NextClade was used to calculate the number of mutations in each amino acid position using 2433 Monkeypox sequences. The Unsupervised Nearest Neighbor machine learning algorithm and ideal matrix [0 0] were used to calculate the conservancy score of epitopes. Six proteins were determined for epitope prediction. Finally, 47 MHC-I epitopes, 5 MHC-II epitopes, and 10 Linear B cell epitopes were discovered. Our method can select epitopes for vaccine design to prevent viruses with accelerated evolution and high mutation rate.

Abstract
The mpox epidemic had spread worldwide and become an epidemic of international concern. Before the emergence of targeted vaccines and specific drugs, it is necessary to numerically simulate and predict the epidemic. In order to better understand and grasp its transmission situation, and take some countermeasures accordingly when necessary, we predicted and simulated mpox transmission, vaccination and control scenarios using model developed for COVID-19 predictions. The results show that the prediction model can also achieve good results in predicting the mpox epidemic based on modified SEIR model. The total number of people infected with mpox on Dec 31, 2022 reached 83878, while the prediction of the model was 96456 with a relative error of 15%. The United States, Brazil, Spain, France, the United Kingdom and Germany are six countries with serve mpox epidemic. The predictions of their epidemic are 30543, 11191, 7447, 5945, 5606 and 4291 cases respectively, with an average relative error of 20%. If 30% of the population is vaccinated using a vaccine that is 78% effective, the number of infected people will drop by 29%. This shows that the system can be practically applied to the prediction of mpox epidemic and provide corresponding decision-making reference.

Abstract
Monkeypox is a viral zoonotic disease rarely found outside Africa. Monkeypox can be spread from person to person through close contact with an infected person, and the rate of transmission is not very high. In addition, monkeypox and variola virus are both pox viruses, and the spread of monkeypox virus was also controlled to some extent by the smallpox campaign, so monkeypox was not widely paid attention to. However, as smallpox vaccination is phased out in various countries or regions, people's resistance to orthopoxviruses is decreasing, especially among people who have not been vaccinated against smallpox. This has led to a significant increase in the frequency and geographical distribution of human monkeypox cases in recent years, and the monkeypox virus has become the orthopoxvirus that poses the greatest threat to public health. Since the last large-scale monkeypox infection was detected in 2022, the number of countries or territories affected has exceeded 100. Many confirmed and suspected cases of monkeypox have been found in individuals who have not travelled to affected areas, and the route of infection is not obvious, making this outbreak of monkeypox a cause for concern globally. The purpose of this systematic review is to further understand the pathophysiological and epidemiological characteristics of monkeypox, as well as existing prevention and treatment methods, with a view to providing evidence for the control of monkeypox.

Abstract
Development and testing of a scale assessing mpox knowledge in a national survey of U.S. adults (aged ≥18 years) was conducted. Address-based sampling methods ensured full coverage of all households. Between September 16-22, 2022, N = 1018 participants self-administered the Internet-based survey that included a 15-item knowledge scale. Responses "yes," "no," and "I do not know," were scored as correct= 1, incorrect= -1, and "I do not know"= 0. Knowledge was dichotomized into good/poor based on modified Bloom's cutoff points (i.e. correctly answering at least 9 of the 15 total questions=good knowledge). We assessed psychometric characteristics and chi-square/one-way ANOVAs examining differences by demographic groups, applying sampling weights to analyses. Score reliability was strong (α = .82). All items but one ("Diarrhea is one of the symptoms of monkeypox") had statistically significant point biserial correlations, indicating a correlation between a correctly answered item and higher knowledge score. Only 35% of respondents were categorized as having good knowledge. Differences in knowledge by racial/ethnic, education, household income, sexual orientation, and MSA status groups were statistically significant. Mpox knowledge was lowest among heterosexually identified, rural, and low education/income respondents. Findings may be used in mpox prevention interventions, as the scale shows promise for assessing mpox knowledge in other groups/settings.

Abstract
BACKGROUND Mpox is a viral illness with a characteristic skin rash caused by the monkeypox virus. In 2022, Mpox spread throughout the world, and an epidemic through domestic transmission started in South Korea in early 2023. This study aimed to summarize the clinical features of Mpox patients in South Korea. METHODS This is a multicenter retrospective study conducted at four hospitals in South Korea. All adult patients diagnosed with Mpox who were admitted to the study hospitals between June 1, 2022 and May 26, 2023 and were discharged by June 30, 2023 were reviewed. RESULTS Sixty patients were included, accounting for 65.9% of Mpox cases reported in South Korea during the study period. Median age was 32 years and 97% (58/60) of patients were male. In total, 85% (51/60) of patients reported their sexual orientation as homosexual or bisexual. The most common route of transmission was sexual or close contact (55/60). Every patient had a skin rash and 88% (53/60) had constitutional symptoms. In total, 42% (25/60) of patients had human immunodeficiency virus and 25% (15/60) had concomitant sexually transmitted infections. Severe manifestations of Mpox were identified in only two patients. CONCLUSION Mpox patients in South Korea were mainly young adult males and were infected through sexual contact. The clinical outcomes were favorable.

Abstract
BACKGROUND Monkeypox (Mpox) virus infection is a topic of growing interest today because of its potential public health impact and concern about possible outbreaks. Reliable and up-to-date sources of information that provide accurate data on its transmission, symptoms, prevention, and treatment are essential for understanding and effectively addressing this disease. Therefore, the aim of the present study is to determine the prevalence of sources of information on Mpox virus infection. METHODS An exhaustive systematic review and meta-analysis was carried out using the information available in the PubMed, Scopus, Web of Science, Embase, and ScienceDirect databases up to August 3, 2023. The data were analyzed using R software version 4.2.3. The quality of the cross-sectional studies that formed part of this review was assessed using the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI) tool. In addition, a subgroup analysis was performed based on the study populations. RESULTS Through electronic searches of five databases, a total of 1833 studies were identified. Twenty-four cross-sectional articles were included, with a total sample of 35,959 participants from 34 countries. The pooled prevalence of each of the included information sources was: social networks reached 59% (95% CI: 50-68%; 29,146 participants; 22 studies; I2 = 100%; p < 0.01); the Internet was 61% (95% CI: 44-77%; 14,002 participants; 5 studies; I2 = 100%; p < 0.01), radio reached 10% (95% CI: 07-13%; 8917 participants; 4 studies; I2 = 93%; p < 0.01), television accounted for 24% (95% CI: 09-43%; 14,896 participants; 8 studies; I2 = 100%; p < 0.01), and the combination of radio and television accounted for 45% (95% CI: 31-60%; 4207 participants; 7 studies; I2 = 99%; p < 0.01); for newspapers, it was 15% (95% CI: 05-27%; 2841 participants; 6 studies; I2 = 99%; p < 0.01), friends and relatives accounted for 19% (95% CI: 12-28%; 28,470 participants; 19 studies; I2 = 100%; p < 0.01), the World Health Organization (WHO) accounted for 17% (95% CI: 07-29%; 1656 participants; 3 studies; I2 = 97%; p < 0.01), the Centers for Disease Control and Prevention (CDC) accounted for 10% (95% CI: 03-21%; 2378 participants; 3 studies; I2 = 98%; p < 0.01), and the combination of WHO and CDC websites accounted for 60% (95% CI: 48-72%; 1828 participants; 4 studies; I2 = 96%; p < 0.01), and finally, scientific articles and journals accounted for 24% (95% CI: 16-33%; 16,775 participants; 13 studies; I2 = 99%; p < 0.01). CONCLUSION The study suggests that people access a variety of information sources to gain knowledge about Mpox virus infection, with a strong emphasis on online sources such as social networks and the Internet. However, it is important to note that the quality and accuracy of information available from these sources can vary, underscoring the need to promote access to reliable and up-to-date information about this disease to ensure public health.

Abstract
Cardiac involvement, such as myocarditis and pericarditis, can be a severe complication of monkeypox virus (mpox) infection and could be related to other co-infections with cardiac involvement. Tecovirimat is an antiviral specifically designed to inhibit smallpox infection diffusion and approved by the FDA for other Orthopoxvirus infections; its efficacy in mpox-infected patients is not well established. We present the case of a cardiac complication during mpox infection in a previously undiagnosed Lyme disease in a 42-year-old man living with HIV. Two days after the typical maculopapular rash, the patient reported a rise in body temperature up to 39 °C, chest pain without irradiation, and shortness of breath. We found an increase in troponin level, a slight reduction in ejection fraction, and grade 2 AV block (Mobitz 1 and 2) with frequent sinus pauses (the longest of 10.1 s). Given the suspicion of myopericarditis with cardiac conduction system involvement, the patient was admitted to the Intermediate Care Unit for continuous monitoring and further evaluation. Treatment included Ibuprofen 600 mg every 12 hours (bid) and colchicine 1 mg once daily for anti-inflammatory purposes. Concomitantly, treatment with tecovirimat was started at 600 mg bid for a total of 14 days. Cardiac MRI with gadolinium showed mild interstitial edema and pericardial enhancement. However, despite the clinical and laboratory resolution of the acute phase, bradycardia with episodes of AV block persisted at follow-up, suggesting the possibility of an additional etiology. Thus, the patient was investigated for Lyme disease because high-degree AV block is the most common presentation of Lyme carditis. Serological results evidenced a previous Borrelia burgdorferi senso latu. We decided to start treatment with doxycycline 100 mg every 12h, even pending the uncertainty of the role of a previous Lyme disease in determining the cardiac rhythm disturbances. At the evaluation on day 44, the patient was systemically well, and after cardiologist consultation, pace-maker implantation was not deemed indicated. This case underscores the importance of considering alternative causes of carditis when the clinical picture remains unclear or persists after the acute phase.

Abstract
BACKGROUND In response to the mpox outbreak, vaccination was offered in the Netherlands to men who have sex with men (MSM) at increased risk for mpox. Successful vaccination campaigns are leveraged by high intent-to-vaccinate, yet intent might not always lead to uptake. Therefore, we assessed the impact of intent-to-vaccinate and other factors on vaccination uptake among participants of the Amsterdam Cohort Studies (ACS). METHOD In July 2022, prior to the mpox vaccination campaign, we distributed an online survey regarding mpox intent-to-vaccinate, as well as e.g. beliefs, attitude, subjective norms, and perception of risk among ACS participants (all MSM). Vaccination uptake was self-reported during study visits after August 2022. The association between vaccination intent and uptake, and determinants of intent, was jointly assessed using a structural equation model (SEM) based on components of the Theory of Planned Behavior (TPB). In a second SEM, determinants of intent were allowed to have a direct effect on vaccination uptake. RESULTS 492 MSM (median age = 46 years) were included in analyses. 380 (77%) had high intent-to-vaccinate and 238 (48%) received at least one vaccine dose. In the first model with a direct relation between intent and uptake only, TBP components predicted intent as expected, and high intent-to-vaccinate was significantly associated with getting vaccinated (β = 1.1, 95%CI = 0.6-1.5). However, 175/380 (46%) participants with high intent-to-vaccinate did not get vaccinated. The second model had an improved model fit compared to the first model. The effect of intent on uptake was non-significant, and only perceiving to be at higher risk of infection significantly increased vaccination uptake later on (β = 0.42, 95%CI = 0.26-0.59). Having a steady relationship decreased the probability of vaccination (β = -0.59, 95%CI = -1.0- -0.18). CONCLUSIONS While intent-to-vaccinate for mpox was high among MSM, high intent did not necessarily result in vaccine uptake. Mpox risk perception might have played a more pivotal role in getting vaccinated, which may be related to the evolution of vaccination eligibility criteria and accessibility to the vaccine.

Abstract
Monkeypox is a viral disease; its outbreak was recently declared a global emergency by the World Health Organization. For the first time, a monkeypox virus (MPXV)-infected patient was found in India. Various researchers back-to-back tried to find the solution to this health emergency just after COVID-19. In this review, we discuss the current outbreak status of India, its transmission, virulence factors, symptoms, treatment, and the preventive guidelines generated by the Indian Health Ministry. We found that monkeypox virus (MPXV) disease is different from smallpox, and the age group between 30-40 years old is more prone to MPXV disease. We also found that, besides homosexuals, gays, bisexuals, and non-vegetarians, it also affects normal straight men and women who have no history of travel. Close contact should be avoided from rats, monkeys and sick people who are affected by monkeypox. To date, there are no monkeypox drugs, but Tecovirimat is more effective than other drugs that are used for other viral diseases like smallpox. Therefore, we need to develop an effective antiviral agent against the virulence factor of MXPV.

Abstract
Purpose Ongoing Monkeypox (MPX) outbreaks in countries outside Africa have unique characteristics. However, data on cohorts of confirmed cases in China is limited. The study provides important epidemiological, diagnostic, and clinical information about this disease in China. Methods We report a series of Chinese individuals with confirmed MPX infections identified at Beijing Youan Hospital (China) from June 10 to July 15, 2023. Samples were taken from the skin, anus, throat, and blood. An epidemiological questionnaire was used to collect demographic and clinical data. Further, we compared the MPX viral (MPXV) loads across different anatomical sites. Results 66 samples were collected from 20 patients, all of whom were cisgender men. Median patient age was 29 years. Notably, 19 (95%) patients reported unprotected sexual encounters with men in the preceding month, and 13 (65%) were human immunodeficiency virus (HIV)-positive. Among those with HIV, 12 (92%) were receiving antiretroviral therapy, and 11 (85%) had well-controlled infections (HIV viral load <40/mL). The median CD4+ T cell count was 667 cells/mm3. In the HIV-negative group, three (43%) patients were taking preexposure prophylaxis. Fifteen patients (75%) had concurrent sexually transmitted infections (50% had syphilis and 65% had HIV) and eight (40%) had HIV and syphilis co-infection. MPXV loads were significantly higher in samples from the skin (cycle threshold value [Ct value]: 19·0) and anus (Ct value: 23.0) compared to samples from the throat (Ct value: 31.0) or blood (Ct value: 34.5). All patients had skin lesions (85% of whom presented with anogenital lesions). Common systemic symptoms included fever (85%) and lymphadenopathy (55%). The median incubation period was 8 d [interquartile range (IQR): 6-16 d]. The median time from the onset of skin lesions to scab removal was 14 d (IQR: 10-16 d). No deaths or severe cases were reported. Conclusion MPXV primarily affects young homosexual men. The high MPXV viral loads in skin and anal lesions indicate that transmission most likely occurs through direct and close body contact. This study also reports high rates of HIV and syphilis co-infection. Therefore, preventive efforts should focus on homosexual men.

Abstract
BACKGROUND Considering the rapidly spreading monkeypox outbreak, WHO has declared a global health emergency. Still in the category of being endemic, the monkeypox disease shares numerous clinical characters with smallpox. This study focuses on determining the most effective combination of autoregressive integrated moving average model to encapsulate time dependent flow behaviour of the virus with short run prediction. METHODS This study includes the data of confirmed reported cases and cumulative cases from eight most burdened countries across the globe, over the span of May 18, 2022, to December 31, 2022. The data was assembled from the website of Our World in Data and it involves countries such as United States, Brazil, Spain, France, Colombia, Mexico, Peru, United Kingdom, Germany and Canada. The job of modelling and short-term forecasting is facilitated by the employment of autoregressive integrated moving average. The legitimacy of the estimated models is argued by offering numerous model performance indices such as, root mean square error, mean absolute error and mean absolute prediction error. RESULTS The best fit models were deduced for each country by using the data of confirmed reported cases of monkeypox infections. Based on diverse set of performance evaluation criteria, the best fit models were then employed to provide forecasting of next twenty days. Our results indicate that the USA is expected to be the hardest-hit country, with an average of 58 cases per day with 95% confidence interval of (00-400). The second most burdened country remained Brazil with expected average cases of 23 (00-130). The outlook is not much better for Spain and France, with average forecasts of 52 (00-241) and 24 (00-121), respectively. CONCLUSION This research provides profile of ten most severely hit countries by monkeypox transmission around the world and thus assists in epidemiological management. The prediction trends indicate that the confirmed cases in the USA may exceed than other contemporaries. Based on the findings of this study, it remains plausible to recommend that more robust health surveillance strategy is required to control the transmission flow of the virus especially in USA.

Abstract
BACKGROUND Immunization, as a preventive strategy against infectious diseases, has consolidated its position as a fundamental pillar in the field of public health. Therefore, the present study aimed to determine the prevalence of the intention to receive the monkeypox (Mpox) vaccine. METHODS A systematic review and meta-analysis of the available evidence was performed using five databases (PubMed, Scopus, Web of Science, Embase, and ScienceDirect) with a search strategy until July 24, 2023. Data analysis was performed in R software version 4.2.3. The quality of the included cross-sectional studies was assessed using the "JBI-MAStARI". In addition, a subgroup analysis by population and continent was developed. RESULTS Twenty-nine cross-sectional articles with a total sample of 52 658 participants were included. The pooled prevalence of intention to vaccinate against Mpox was 61% (95% CI: 53-69%; 52,658 participants; 29 studies; I2 = 100%). In the subgroup analysis, the intention to be vaccinated against Mpox according to continents was 64% (95% CI: 53-74%; 13,883 participants; 17 studies; I2 = 99%) in Asian countries, 43% (95% CI: 39-47%; 1538 participants; 3 studies; I2 = 53%) in African countries, 62% (95% CI: 45-78%; 35,811 participants; 6 studies; I2 = 99%) in European countries, and 63% (95% CI: 32-89%; 1426 participants; 3 studies; I2 = 99%) in American countries. In the subgroup analysis on the intention to be vaccinated against Mpox, according to study subjects, it was 54% (95% CI: 45-62%; 10,296 participants; 11 studies; I2 = 99%) in the general population, 57% (95% CI: 33-79%; 3333 participants; 10 studies; I2 = 99%) in health care workers, and 76% (95% CI: 70-82%; 39,029 participants; 8 studies; I2 = 98%) in the lesbian, gay, bisexual, transgender, and intersex (LGBTI) community. In addition, as a secondary outcome, a prevalence of refusal of Mpox vaccination was found to be 22% (95% CI: 16-30%; 45,577 participants; 21 studies; I2 = 99%). CONCLUSION The study highlights the importance of recognizing regional and subgroup disparities in Mpox vaccine willingness and refusal. It emphasizes the importance of employing strategies to achieve widespread vaccination coverage and safeguard public health worldwide.

Abstract
The monkeypox virus (MPXV), belonging to the genus Orthopoxvirus, is responsible for causing the zoonotic illness known as Monkeypox. The virus was initially identified during an outbreak at a Danish Zoo in 1958 and has since been found to infect various mammal species worldwide. While African squirrels and other rodents are believed to be the primary hosts, determining the natural host has proven challenging. While MPXV can be studied using different animal models in laboratory settings, understanding its natural transmission routes remains complex and species-dependent. Recent developments have elevated the global health concern surrounding Monkeypox, leading to its designation as a Global Health Emergency of International Concern on 23 July 2022. Enhancing surveillance and case detection is crucial in navigating the unpredictable epidemiology of this re-emerging disease. Human infections with the monkeypox virus are becoming less frequent due to population growth and economic improvements. Monkeypox, similar to smallpox, can potentially be controlled and eradicated in the future through vaccines, appropriate treatment, and personal protective equipment.

Abstract
This meta-analysis aims to investigate demographic disparities in monkeypox (mpox) infections among various groups based on ethnicity, sexual partners, and gender. The study includes data from 2,646 to 4,002 patients across various outcomes. Among racial demographics, black populations show a lower odds ratio for mpox compared to white populations (OR=0.08 [0.01, 0.45], 95% CI, p=0.004). However, no statistically significant difference is found when comparing black populations with Hispanic or Asian populations (OR=0.72 [0.46, 1.11], p=0.13). There was a substantial disparity between gay, bisexual and other men-who-have-sex-with-men (GBMSM) and heterosexual populations, with significantly higher odds of mpox among the former (OR=393.80, 95% CI: [82.45, 180.85], p<0.00001). Analysis of sexual partners indicates a significant difference in infection risk between individuals with zero to one sexual partner and those with more than two partners (OR=0.06 [0.01, 0.28], p=0.0005). Additionally, there is a substantial difference in infection risk between male and female populations (OR=3868.02, p<0.00001). These findings emphasize the importance of considering demographic factors in understanding mpox transmission and risk profiles. Targeted research and intervention strategies are required to address the identified disparities and mitigate the spread of mpox.

Abstract
Sexually transmitted infections (STIs) deserve more attention today than ever in the tropics. Indeed, the emergence of monkeypox in 2022 in Western countries reminds the risk of exporting STIs from the tropics as it was already known for decades with the worldwide spread of HIV/AIDS infection from tropical Africa. Some hazards are already well identified. According to WHO 2023 report STIs are increasing in the world. Antibiotic resistance is increasing for Neisseria gonorrhoeae, and already well established for Mycoplasma genitalium, whereas Treponema pallidum has become resistant to macrolides within the last twenty years. Some neglected tropical diseases (Zika, Ebola, monkeypox) can also be sexually transmitted, sometimes months after cure (Ebola). In this setting, the use of PrEP in migrants, and in Africa, is worth to be discussed beyond traditional circles.

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.

Abstract
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.

Abstract
Monkeypox is a zoonotic viral disease that mainly affects tropical rainforest regions of central and west Africa, with sporadic exportations to other places. Since there is no cure, treating monkeypox with an antiviral drug developed for smallpox is currently acceptable. Our study mainly focused on finding new therapeutics to target monkeypox from existing compounds or medications. It is a successful method for discovering or developing medicinal compounds with novel pharmacological or therapeutic applications. In this study, homology modelling developed the Monkeypox VarTMPK (IMNR) structure. Ligand-based pharmacophore was generated using the best docking pose of standard ticovirimat. Further, molecular docking analysis showed compounds, tetrahydroxycurcumin, procyanidin, rutin, vicenin-2, kaempferol 3-(6''-malonylglucoside) were the top five binding energy compounds against VarTMPK (1MNR). Furthermore, we carried out MD simulations for 100 ns for the six compounds, including reference based on the binding energies and interactions. MD studies revealed that as ticovirimat interacted with residues Lys17, Ser18, and Arg45, all the above five compounds interacted with the same amino acids at the active site during docking and simulation studies. Among all the compounds, ZINC4649679 (Tetrahydroxycurcumin) was shown to have the highest binding energy -9.7 kcal/mol and also observed stable protein-ligand complex during MD studies. ADMET profile estimation showed that the docked phytochemicals were safe. However, further biological assessment through a wet lab is essential to measure the efficacy and safety of the compounds.Communicated by Ramaswamy H. Sarma.

Abstract
Background This report details how one large medical center in the Metropolitan New York area re-purposed a drive-through COVID-19 vaccination structure to handle a surge in Mpox cases in July 2022.Methods/Results: Simultaneous to on-going COVID -19 vaccination and testing, Mpox vaccination was rolled out in the same drive through structure. More than 1,820 Jynneos (Smallpox and Monkeypox Vaccine, Live, Non-replicating) vaccine dosages were delivered subcutaneously and then intradermally to 1,123 individuals through the open window of their vehicles, averaging 8-10 patients an hour. Five vaccine recipients suffered Mpox rash; there was no exposure among healthcare providers. Conclusion Drive-through vaccination is an efficient model to be redeployed for future unexpected vaccine initiatives.

Abstract
Monkeypox virus (Mpxv) is a dsDNA virus that has become a global concern for human health in 2022. As both infected people and non-human hosts can shed the virus from their skin, faeces, urine and other body fluids, and the resulting sewage contains viral load representative of the whole population, it is highly promising to detect the spread of monkeypox virus in municipal wastewater. We established a methodology for sewage-based monitoring of Mpxv in Prague and analysed samples (n = 24) already early August-October of 2022 in a municipality with 1.4 million inhabitants that only reported 29 cumulative cases in this period. We isolated Mpxv DNA with the Wizard Enviro Total Nucleic Acid Kit, and thereafter detected Mpxv DNA using the EliGene® Monkeypox RT-PCR Kit. Prague wastewater was positive for Mpxv (in total 9 positive samples in periods with 1-9 new cases per week, coinciding with a weekly incidence of 0.07-0.64 per 100,000 inhabitants. The method for confirmation of wastewater positivity via semi-nested PCR and Sanger sequencing was successfully confirmed on positive controls including Mpxv particles and Mpxv-positive wastewater from the Netherlands. However, for Prague wastewater samples, amplification of Mpxv DNA via semi-semi-nested PCR was unsuccessful. This was probably due to extremely low case count, leading to the amplification of non-target bacterial DNA. Compared to other studies with much higher Mpxv prevalence, we show the outstanding sensitivity of our approach for monitoring the spread of monkeypox using wastewater.
