What is monkeypox? Monkeypox is a contagious disease caused by a virus. The name monkeypox is used for both the disease and the virus that causes it. Monkeypox typically causes a rash that can start as painful, blisterlike bumps on the skin, especially on or near the genitals, the anus, and other areas such as the hands, feet, face, and chest. Monkeypox is similar to smallpox but usually less severe. While most cases are not severe, monkeypox can cause serious illness. Monkeypox is sometimes abbreviated as or alternately referred to as MPX, MPOX, MPV (for monkeypox virus), MPXV, or in other ways.
