Monkeypox: A Comprehensive Review.

ABSTRACT: The 2022 multi-country monkeypox outbreak in humans has brought new public health adversity on top of the ongoing coronavirus disease 2019 (COVID-19) pandemic. The disease has spread to 104 countries throughout six continents of the world, with the highest burden in North America and Europe. The etiologic agent, monkeypox virus (MPXV), has been known since 1959 after isolation from infected monkeys, and virulence among humans has been reported since the 1970s, mainly in endemic countries in West and Central Africa. However, the disease has re-emerged in 2022 at an unprecedented pace, with particular concern on its human-to-human transmissibility and community spread in non-endemic regions. As a mitigation effort, healthcare workers, public health policymakers, and the general public worldwide need to be well-informed on this relatively neglected viral disease. Here, we provide a comprehensive and up-to-date overview of monkeypox, including the following aspects: epidemiology, etiology, pathogenesis, clinical features, diagnosis, and management. In addition, the current review discusses the preventive and control measures, the latest vaccine developments, and the future research areas in this re-emerging viral disease that was declared as a public health emergency of international concern.

Project description:During the COVID-19 pandemic, the increase in reports of human monkeypox virus infection cases spreading in many countries outside Africa is a major cause for concern. Therefore, this study aimed to explore the evidence of antiviral pharmacotherapy available for the treatment of adult patients with monkeypox. A scoping review of the literature was conducted using PubMed, Scopus, Web of Science, Embase, and CENTRAL databases until 12 September 2022. The key search terms used were "monkeypox" and "treatment". A total of 1927 articles were retrieved using the search strategy. After removing duplicates (n = 1007) and examining by title, abstract, and full text, 11 studies reporting case reports of monkeypox with antiviral treatment were included, detailing the number of monkeypox cases, clinical manifestations, number of participants with antiviral treatment, history of sexually transmitted diseases, method of diagnosis, location of skin lesions, drugs used in antiviral treatment, route of administration, and outcome. A total of 1281 confirmed cases of monkeypox have been reported, of which 65 monkeypox cases had antiviral treatment distributed most frequently in the United States (n = 30), the United Kingdom (n = 6), and Spain (n = 6). Of the total cases, 1269 (99.1%) were male with an age range of 18 to 76 years, and 1226 (95.7%) had a sexual behavior of being men who have sex with men. All confirmed cases of monkeypox were diagnosed by reverse transcriptase polymerase chain reaction (RT-PCR). The most frequent clinical manifestations were skin lesions, fever, lymphadenopathy, headache, fatigue, and myalgia. The most frequent locations of the lesions were perianal, genital, facial, and upper and lower extremities. The most commonly used drugs for antiviral treatment of monkeypox were: tecovirimat, cidofovir, and brincidofovir. All patients had a complete recovery. According to current evidence, the efficacy and safety of antiviral drugs against monkeypox is of low quality and scarce.

Project description:ObjectiveThe World Health Organization has recently declared a monkeypox outbreak as a public health emergency of global concern. The main aim of this systematic review was to ascertain the maternal and perinatal outcomes of pregnancies complicated by monkeypox infection.Data sourcesThe Medline, Embase, and Cochrane databases were searched on June 25, 2022 utilizing combinations of the relevant medical subject heading terms, key words, and word variants for "monkeypox" and "pregnancy."Study eligibility criteriaThe search and selection criteria were restricted to the English language.MethodsThe outcomes observed were miscarriage; intrauterine, neonatal, and perinatal death; preterm birth, vertical transmission, and maternal symptoms. A metaanalysis of proportions was used to analyze the data.ResultsFour studies were included. All the cases in the present systematic review presented with symptoms and signs of monkeypox infection. There was no case of maternal death. Miscarriage occurred in 39% of cases (95% confidence interval, 0-89.0), whereas intrauterine fetal death occurred in 23.0% (95% confidence interval, 0-74.0) of cases. The overall incidence of late fetal and perinatal loss was 77.0% (95% confidence interval, 26.0-100), whereas only 23% (95% confidence interval, 0-74.0) of the included fetuses survived to birth. The incidence of preterm birth before 37 weeks of gestation was 8.0% (95% confidence interval, 0-62.0). Vertical transmission occurred in 62.0% (95% confidence interval, 3.0-100) of cases. When stratifying the analysis according to gestational age at infection, fetal loss was found to occur in 67.0% (95% confidence interval, 9.0-99.0) of cases with first-trimester infection and in 82.0% (95% confidence interval, 17.0-100) of those with second-trimester infection.ConclusionMonkeypox infection in pregnancy is associated with a high risk of perinatal loss and vertical transmission. The preliminary results from this systematic review affected by a very small number of included cases highlight the need for thorough maternal and fetal surveillance in pregnancies complicated by monkeypox infection.
