Monkeypox is a viral disease that results from monkeypox virus infection. The infection was discovered in 1959 after monkeys shipped to the Denmark research center from Singapore fell ill. The first case of human infection was affirmed in 1970 following the separation of the virus from a child suspected to be suffering from smallpox in the Democratic Republic of Congo (DRC). With the rate of disease incidents reported outside of sub-Saharan Africa, the virus became endemic in countries within West and Central Africa. Coincident immunity to the monkeypox virus was initially attained with vaccinia immunization. However, monkeypox achieved tremendous clinical relevance due to constant efforts to eradicate smallpox and the subsequent lack of immunization. Moreover, there is the potential for underreporting of monkeypox due to its high prevalence in rural Africa, which translates to an underestimation of the severity of the pathogen (Moore et al., 2023). The United States (U.S.) Centers for Disease Control and Prevention (CDC) noted that there were over 57,995 recorded cases of monkeypox across 100 territories or countries, as shown in Figure 1 below (Huang et al., 2022). This research paper evaluates monkeypox infection in terms of pathophysiology, clinical manifestations, epidemiology, vaccination, diagnosis, and treatment and management, as well as offers a discussion that summarizes the points established in the report.

Pathophysiology
After the virus enters the human body via any route (intradermal, nasopharynx, or oropharynx), it replicates at the inoculation point and then advances to localized lymph nodes. Accordingly, viral spread and other organ seeding happen due to the initial viremia. This depicts the illness incubation timescale, which generally lasts seven to fourteen days, with a twenty-one-day upper limit. The symptom onset is linked to secondary viremia, which results in one to two days of prodromal clinical manifestations, including lymphadenopathy and fever, before the appearance of lesions. The infected patient is typically contagious during this timescale. Lesions begin within the oropharynx and then spread to the skin. When lesions appear, serum antibodies can be detected (Moore et al., 2023).
Clinical Manifestations
The signs and symptoms of monkeypox typically begin within three weeks after the individual is exposed to the monkey virus, typically lasting for two to four weeks. Notably, the clinical manifestations of monkeypox are significantly identical to smallpox infection indications. Typically, the infected person manifests flu-like symptoms. The typical initial symptoms include fatigue, backache, muscle aches, headache, and fever (World Health Organization, 2023). Following the onset of lymphadenopathy and fever, rashes will likely appear within one to three days. The patient remains contagious from when the signs and symptoms begin up to when the rash completely heals (Soheili & Nasseri, 2022). The significant distinguishing difference between smallpox and monkeyp...
