Background: Human monkeypox is a zoonosis caused by the monkeypox virus, an orthopoxvirus and close relative of variola virus, the causative agent of smallpox. The disease was first reported in central Africa in 1970, where it continues to be endemic and has historically affected some of the poorest and most marginalized communities in the world. The condition has recently attracted global attention due to >14,000 cases, including five deaths, reported by the World Health Organization, and a total of 5189 confirmed monkeypox cases in the United States reported by the Centers for Disease Control and Prevention as of July 29, 2022. On July 23, 2022, the World Health Organization declared the current monkeypox outbreak a Public Health Emergency of International Concern. Objective: The purpose of the present report was to review the epidemiology of monkeypox viral infection; its clinical manifestations; and current recommendations for diagnosis, treatment, and use of vaccines for prevention of the disease, with a focus on those aspects that have particular relevance to the allergist/immunologist. Results: Monkeypox was discovered in the early 1970s and, for years, has been well described by researchers in west and central Africa, where the disease has been present for decades. Although this outbreak thus far has mostly affected men who have sex with men, it is possible that the disease could become endemic and could begin spreading in settings where there is close physical contact, which is how the virus is transmitted. Conclusion: Monkeypox is a different viral infection from the coronavirus. Unlike the coronavirus, which is an extremely contagious respiratory pathogen, monkeypox is primarily transmitted through body fluids and/or prolonged skin-to-skin contact. Although the control of monkeypox will require renewed efforts and resources, we have learned much from the past and have the tools to stop this virus from becoming yet another serious illness with which Americans have to contend. The allergist/immunologist can play a significant role.
