Monkeypox is a rare disease caused by infection with the Monkeypox virus. Monkeypox virus is part of the same family of viruses as variola virus, the virus that causes smallpox. Monkeypox symptoms are similar to smallpox symptoms, but milder, and monkeypox is rarely fatal. Monkeypox is not related to chickenpox.
People with monkeypox get a rash that may be located on or near the genitals (penis, testicles, labia, and vagina) or anus and could be on other areas like the hands, feet, chest, face, or mouth. The rash will go through several stages, including scabs, before healing. The rash can initially look like pimples or blisters and may be painful or itchy.
Other symptoms of monkeypox can include:
- Swollen lymph nodes
- Muscle aches and backache
- Respiratory symptoms (e.g. sore throat, nasal congestion, or cough)
- You may experience all or only a few symptoms
- Sometimes, people have flu-like symptoms before the rash.
- Some people get a rash first, followed by other symptoms.
- Others only experience a rash.
How long do monkeypox symptoms last?
Monkeypox symptoms usually start within 3 weeks of exposure to the virus. If someone has flu-like symptoms, they will usually develop a rash 1-4 days later. Monkeypox can be spread from the time symptoms start until the rash has healed, all scabs have fallen off, and a fresh layer of skin has formed. The illness typically lasts 2-4 weeks.
