Abstract

The human monkeypox virus (MPXV) was first identified in 1959. Since then, the incidence of the disease has been sporadic. The endemic regions were identified in Africa's central and western areas. However, the infection started to spread in 2017 to non-endemic regions such as North and South America, Europe, and Asia. Since May 2022, the non-endemic areas reported 62,635 till 20th September 2022. Although the monkeypox virus has a mortality of ≥ 10%, it showed only 82 mortalities worldwide in 2022. The common symptoms include chills, fever, fatigue, and skin lesions, and the complications include secondary respiratory tract infections, encephalitis, blindness, and severe diarrhea. The factors responsible for spreading the virus include improper handling and consumption of infected bushmeat, unprotected sexual intercourse, contact with an infected person, no smallpox vaccination, improper hygiene, lower diagnostic capacity, and strong travel history from the endemic regions. The therapeutic strategy is symptom-based treatment and supportive care. Antivirals and vaccines such as Tecovirimat, Brincidofovir, Cidofovir, Imvamune, and ACAM2000 have shown promising results. The primary purpose of the review is to perform an epidemiological study and investigate the pathobiology, diagnosis, prevention, treatment, and some associated complications of the monkeypox virus in 2022.
