Monkeypox is a disease caused by an orthopoxvirus in the same family as smallpox and cowpox. It was first identified in monkeys in Africa in the late 1950s, with the first transmission to humans being recorded in the 1970s. Infected individuals will usually develop flu-like symptoms which last 2-3 weeks as well as a rash. The rash can leave scars, similar to chickenpox.
