Mpox (formerly known as Monkeypox) is a rare disease caused by infection with the mpox virus. Mpox virus is part of the same family of viruses as variola virus, the virus that causes smallpox. Mpox symptoms are similar to smallpox symptoms, but milder, and mpox is rarely fatal. Mpox is not related to chickenpox. The Center for Disease Control and Prevention (CDC) is tracking an outbreak of mpox that has spread across several countries that do not normally report mpox, including the United States. Cases of mpox have been reported in Iowa.
