Mpox is a rare disease caused by infection with the mpox virus and is in the same family as smallpox. While symptoms are similar to smallpox, mpox is typically milder and rarely fatal. Mpox can spread to anyone through close, personal, often skin-to-skin contact. Symptoms of mpox include:
- Muscle aches and backache
- Swollen lymph nodes
- A rash that looks like pimples or blisters that appears on the face, inside the mouth, and on other parts of the body, like the hands, feet, chest, genitals, or anus.
