Monkeypox is a viral disease that resembles smallpox, but unlike smallpox, is spread by animals, such as prairie dogs. It was first discovered in 1958 when two outbreaks of a pox-like disease occurred in colonies of monkeys kept for research, hence the name ‘monkeypox.’ Monkeypox mostly occurs in central and western African countries. Symptoms begin with fever, headache, muscle aches, and exhaustion. The main difference between symptoms of smallpox and monkeypox is that monkeypox causes lymph nodes to swell (lymphadenopathy) while smallpox does not.
