The mpox (formerly monkeypox) virus is part of the same family of viruses as smallpox, which was eradicated through global vaccination efforts in 1980. Mpox symptoms are similar but less severe than smallpox and mpox is rarely fatal. Mpox infections are common in several forested areas of central and wester Africa. However, since May 2022, the virus has been spreading in the U.S. and globally. Overal risk to the public remains low. Mpox is not related to chickenpox and is much less transmissible that smallpox and respiratory diseases like the virus that causes COVID-19.
