Abstract The human monkeypox (mpox) virus is an orthopox virus that can be transmitted to humans. Though the disease has been endemic in Africa, the recent mpox outbreak since May 2022. We attempted to examine differences between the endemic form of mpox and the current outbreak. Review of electronic medical database with relevant keywords. The current outbreak of mpox has disproportionately impacted the gay, bisexual and other men who have sex with men (MSM) community. This is also the first time that widespread semen testing has turned up evidence of mpox viral deoxyribonucleic acid (DNA). Cases in the present outbreak are more likely to affect adults, involve the genitalia, and have no prodrome. Close diagnostic differentials include varicella and hand-foot-mouth disease. The disease is usually self-limiting; though secondary infections, anorectal pain, pharyngitis, ocular lesions and rarely, renal injury and myocarditis may occur. This review focuses primarily on the novel clinical characteristics and emerging sexual transmission route of the mpox virus, which, although unconfirmed, appears extremely likely as the route of spread. Dermatologists have an important role in this health emergency, as early diagnosis can cause a significant reduction in disease transmission.
