Monkeypox: What we know so far
Monkeypox (hMPXV) is a disease caused by infection with the monkeypox virus, which is related to the smallpox virus. While it's usually less severe and contagious than smallpox, monkeypox can be unpleasant. Occasionally, it can be serious.
Before 2022, monkeypox was not seen in the United States often, but it's common in other parts of the world.
Contrary to what you may have heard, the disease is not a sexually transmitted infection. However, it is spread through close, prolonged, skin-to-skin contact with people who have symptoms such as a rash or lesions.
