Review
Monkeypox or Mpox is an infectious virus predominantly found in Africa. It has spread to many countries since its latest outbreak. Symptoms such as headaches, chills, and fever are observed in humans. Lumps and rashes also appear on the skin (similar to smallpox, measles, and chickenpox). Many artificial intelligence (AI) models have been developed for accurate and early diagnosis. In this work, we systematically reviewed recent studies that used AI for mpox-related research. After a literature search, 34 studies fulfilling prespecified criteria were selected with the following subject categories: diagnostic testing of mpox, epidemiological modeling of mpox infection spread, drug and vaccine discovery, and media risk management. In the beginning, mpox detection using AI and various modalities was described. Other applications of ML and DL in mitigating mpox were categorized later. The various machine and deep learning algorithms used in the studies and their performance were discussed. We believe that a state-of-the-art review will be a valuable resource for researchers and data scientists in developing measures to counter the mpox virus and its spread.

Meta-Analysis Review
Mpox is a zoonotic disease that became epidemic in multiple countries in 2022. There is a lack of published systematic reviews on natural animal infection due to Mpox. We performed a systematic literature review with meta-analysis to assess animal Mpox prevalence. We performed a random-effects model meta-analysis to calculate the pooled prevalence and 95% confidence interval (95%CI) for prevalence studies. After the screening, 15 reports were selected for full-text assessment and included in qualitative and quantitative analyses. Ten reports assessed Mpox infection by molecular or serological tests (n = 2680), yielding a pooled prevalence of 16.0% (95%CI: 3.0-29.0%) for non-human primates; 8.0% (95%CI: 4.0-12.0%) for rodents and 1.0% (95%CI: 0.0-3.0%) for shrews. Further studies in other animals are required to define the extent and importance of natural infection due to Mpox. These findings have implications for public human and animal health. OneHealth approach is critical for prevention and control.

BACKGROUND
Monkeypox was designated as an emerging illness in 2018 by the World Health Organization Research and Development Blueprint, necessitating expedited research, development, and public health action. In this review, we aim to shed the light on the imported cases of monkeypox in attempt to prevent the further spread of the disease. Methodology An electronic search in the relevant database (Web of Science, PubMed Medline, PubMed Central, Google scholar, and Embase) was conducted to identify eligible articles. In addition to searching the grey literature, manual searching was carried out using the reference chain approach.
RESULTS
A total of 1886 articles were retrieved using the search strategy with 21 studies included in the systematic review. A total of 113 cases of imported monkeypox were confirmed worldwide. Nineteen patients mentioned a travel history from Nigeria, thirty-eight infected cases had travel destinations from Europe, fifty-four cases traveled from European countries such as; Spain, France, and the Netherlands, one case from Portugal, and another one from the United Kingdom (UK). All reported clades of the virus were West African clade. Nine studies showed the source of infection was sexual contact, especially with male partners. Six studies mentioned the cause of infection was contact with an individual with monkeypox symptoms. Two studies considered cases due to acquired nosocomial infection. Ingestion of barbecued bushmeat was the source of infection in three studies and rodent carcasses were the source of infection in the other two studies.
CONCLUSION
The development of functioning surveillance systems and point-of-entry screening is essential for worldwide health security. This necessitates ongoing training of front-line health professionals to ensure that imported monkeypox is properly diagnosed and managed. In addition, implementing effective health communication about monkeypox prevention and control is mandatory to help individuals to make informed decisions to protect their own and their communities' health.

Review
Public health officials around the world are extremely concerned about the global outbreak of monkeypox (MPX), which has been claimed to have originated in Africa. As a result, studies into the origins and reasons behind the outbreak's rapid spread have been sped up. The goal of the current investigation is to determine whether the monkeypox virus (MPXV) is present in seminal fluid samples from MPX cases that have been verified. Up until 6 January 2023, PubMed, Scopus, Web of Science, Embase, and ScienceDirect databases were used to conduct a thorough evaluation of the literature. The search technique returned a total of 308 items. Fourteen studies reporting the presence of MPXV in the seminal fluid of MPX-confirmed cases were included after the duplicates ( = 158) and searches by title, abstract, and full text were eliminated. In 84 out of the 643 confirmed MPX cases (13.06% or = 643), MPXV was discovered in seminal fluid. Reverse transcriptase polymerase chain reaction (RT-PCR) was used to identify MPXV, and samples taken from skin lesions (96.27%), pharynx or oropharynx (30.48%), and blood all had higher positivity rates than other samples (12.44%). Additionally, 99.85% of respondents were male with a mean age of 36, 98.45% engaged in MSM (men who have sex with men) sexual conduct, and human immunodeficiency virus (HIV) accounted for 56.9% of all STD cases. This study offers proof that MPXV can be found in the seminal fluid of MPX sufferers. Our data imply that MPXV transmission is a possibility in these samples and that MSM are more vulnerable to it. The creation of hygienic standards is essential for the early identification of MPX cases.

Review
BACKGROUND
The review aimed at examining patient factors that were associated with the worldwide geographic variation in number of monkeypox cases during the 2022 outbreak.
METHODS
A systematic search was conducted using Scopus, Google Scholar, and PubMed/MEDLINE, to identify studies published in the year 2022 until 30 September on the 2022 monkeypox outbreak. Studies that described demographics and patient characteristics of the affected populations were eligible. Only countries/regions with the highest and lowest globally reported numbers were included.
RESULTS
A total of 24 eligible studies reported data from the most affected countries in Europe [Spain and UK]; Americas [USA and Brazil]; and the least affected region [South East Asia]. There were no eligible studies reporting data from the Eastern Mediterranean which was allegedly the least affected region. Cases from Europe and the Americas were mostly men having sex with men [MSM], in fourth and fifth decades of life, with a substantial proportion of HIV and sexually transmitted diseases. Sporadic cases among women [sexual, household] and children [household] were identified. Sexual orientation and/or mode of transmission were not clearly stated in most studies from South East Asia.
CONCLUSIONS
The 2022 monkeypox outbreak was most obvious in the western part of the globe due mainly to sexual activities among MSM. Low numbers in the east may indicate the influence of the conservative social behaviors. Co-morbidities in the form of HIV and sexually transmitted diseases were identified. Detection of the disease among women and children highlights the importance of adopting appropriate preventive public health measures.

Review
Human monkeypox virus (MPVX) infection represents an emerging zoonotic disease caused by an orthopoxvirus, resulting in a condition reminiscent of smallpox. More recent developments have witnessed a notable surge in global MPVX outbreaks, eliciting significant concerns. We aimed to investigate the epidemiological factors of the emerging human monkeypox virus infection, including the number of suspected, confirmed, and fatal cases, as well as the risk factors for contracting monkeypox infection. We performed a systematic review of peer-reviewed literature by following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. An electronic database search (PubMed, Wiley Online Library, and Science Direct) was undertaken. For monkeypox-related studies, we included 25 peer-reviewed articles from 2018 and 2022, and data were extracted on the current evidence on the cases and the risk factors for MPVX infection, to develop public health advisories. Our reports show a rapid rise of MPVX cases in the highly endemic African regions after the 1970s, spread to other countries, and an increase in the median age from young children to young adults. The cessation of smallpox vaccination might have been one of the factors responsible for these findings. As of 2022, the genomic sequences of ten MPVX strains associated with the recent countrywide outbreak have been determined. While the West African Clade has been primarily implicated in the recent viral surge, data were insufficient to determine which mutation contributed to increased transmissibility. In the Democratic Republic of the Congo (DRC), sleeping on the floor was significantly associated with contracting MPVX, while eating or processing of animal foods was not a significant risk factor. In the United States, cleaning the cages and bedding of sick animals, touching infected animals, and daily exposure to sick animals were associated with an increased probability of contracting the MPVX infection. Recent global outbreaks and the rising incidence of MPVX infections among young adults in the endemic zones might be a result of the cessation of the smallpox vaccine. The increased risk associated with exposure to sick animals or sleeping on the floor suggests high infectivity from animal excretions. Increasing awareness, strict surveillance, and contact tracing can help contain global outbreaks. The ring vaccination approach for exposed individuals is another potential disease containment strategy. Future studies should investigate measures for rapid laboratory diagnosis, maintaining lab safety, and transmissibility.

BACKGROUND AND AIMS
The 2022-mpox outbreak has spread worldwide in a short time. Integrated knowledge of the epidemiology, clinical characteristics, and transmission of mpox are limited. This systematic review of peer-reviewed articles and gray literature was conducted to shed light on the epidemiology, clinical features, and transmission of 2022-mpox outbreak.
METHODS
We identified 45 peer-reviewed manuscripts for data analysis. The standards of the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) Statement and Cochrane Collaboration were followed for conducting the study.
RESULTS
The case number of mpox has increased about 100 times worldwide. About 99% of the cases in 2022 outbreak was from non-endemic regions. Men (70%-98% cases) were mostly infected with homosexual and bisexual behavior (30%-60%). The ages of the infected people ranged between 30 and 40 years. The presence of HIV and sexually transmitted infections among 30%-60% of cases were reported. Human-to-human transmission via direct contact and different body fluids were involved in the majority of the cases (90%-100%). Lesions in genitals, perianal, and anogenital areas were more prevalent. Unusually, pharyngitis (15%-40%) and proctitis (20%-40%) were more common during 2022 outbreak than pre-2022 outbreaks. Brincidofovir is approved for the treatment of smallpox by FDA (USA). Two vaccines, including JYNNEOSTM and ACAM2000®, are approved and used for pre- and post-prophylaxis in cases. About 100% of the cases in non-endemic regions were associated with isolates of IIb clade with a divergence of 0.0018-0.0035. Isolates from B.1 lineage were the most predominant followed by B.1.2 and B.1.10.
CONCLUSION
This study will add integrated knowledge of the epidemiology, clinical features, and transmission of mpox.

Review
Due to the rapid evolution of the monkeypox virus, the means by which the monkeypox virus is spread is subject to change. Therefore, the present study aims to analyze the detection of the monkeypox virus according to the collection site of samples from confirmed monkeypox cases. A systematic literature review was performed using PubMed, Scopus, Web of Science, and Embase databases until 5 October 2022. A total of 1022 articles were retrieved using the search strategy. After removing duplicates ( = 566) and examining by title, abstract, and full text, 65 studies reporting monkeypox case reports were included with a detailed description of risk factors, sexually transmitted infections (STIs), site of monkeypox virus-positive specimens, location of skin lesions, and diagnostic test. A total of 4537 confirmed monkeypox cases have been reported, of which 98.72% of the cases were male with a mean age of 36 years, 95.72% had a sexual behavior of being men who have sex with men, and 28.1% had human immunodeficiency virus (HIV). The most frequent locations of lesions in patients diagnosed with monkeypox were: 42.85% on the genitalia and 37.1% in the perianal region. All confirmed monkeypox cases were diagnosed by reverse transcriptase polymerase chain reaction (RT-PCR), and the most frequent locations of samples collected for diagnosis that tested positive for monkeypox virus were: 91.85% from skin lesions, 20.81% from the oropharynx, 3.19% from blood, and 2.43% from seminal fluid. The disease course of the cases with monkeypox was asynchronous, with no severe complications, and most patients did not report specific treatment but simply followed a symptomatic treatment.

BACKGROUND
Monkeypox is a zoonotic viral infection first reported in May 2022. Monkeypox cases present with prodromal symptoms, rash, and/or systemic complications. This study systematically reviews the monkeypox cases presented with any cardiac complications.
METHODS
A systematic literature search was done to locate papers that discuss any cardiac complications associated with monkeypox; then, data were analyzed qualitatively.
RESULTS
Nine articles, including the 13 cases that reported cardiac complications of the disease, were included in the review. Five cases previously had sex with men, and two cases had unprotected intercourse, which reveals the importance of the sexual route in disease transmission. All cases have a wide spectrum of cardiac complications, such as acute myocarditis, pericarditis, pericardial effusion, and myopericarditis.
CONCLUSION
This study clarifies the potential for cardiac complications in monkeypox cases and provides avenues for future research to determine the underlying mechanism. Also, we found that the cases with pericarditis were treated with colchicine, and those with myocarditis were treated with supportive care or cardioprotective treatment (Bisoprolol and Ramipril). Furthermore, Tecovirimat is used as an antiviral drug for 14 days.

Monkeypox has been declared as a Public Health Emergency of International Concern (PHEIC) by the WHO Director General (WHO-DG). Most of the G20 nations have reported Monkeypox outbreak. Policies developed and implemented in G20 countries for the prevention and control of monkeypox preparedness and response have global consequences. This rapid review aimed to map the monkeypox prevention and control policies planned and implemented in G20 nations in line with temporary recommendations issued by the WHO-DG. We mapped monkeypox prevention and control policies in G20 nations based on the WHO-DG recommendations. Medline (through PubMed), Scopus, and ProQuest Health and Medical Complete were searched to understand G20 preventative, diagnostic, and therapeutic policies. We also performed an extensive gray literature search through the Ministry of Health websites and newspaper through Google. The documents/ studies that had an information on prevention, control and management guidelines/policies and published through journal, news articles and health ministry websites of G20 nations on monkeypox were included. We excluded the editorials, opinion, and perspective papers and studies published prior to May 6, 2022. We obtained 671 articles with 10 articles included in the review. Additionally, we identified 55 documents from the gray literature. We included national guidelines of the 18 countries on the control, prevention, and management of monkeypox. National guidelines were compared with the WHO guidelines in terms of implementing coordinated response, engaging and protecting communities, surveillance and public health measures and international travel, clinical management and infection, prevention and control (IPC) measures and medical countermeasures research. Depending on the availability of resources, some recommendations are followed by nations while others are not. Coordinated response among states is key to contain the transmission of monkeypox. To bring a coordinated response, G20 nations are following temporary recommendations that are context specific to their nation.
