 Monkeypox: An Emerging Infectious Disease Affecting Humans Monkeypox, a rarely occurring viral zoonotic disease, has recently gained attention due to its potential to spread and cause outbreaks in humans. The disease, which was first identified in 1958 in monkeys, has since been found in several African countries, with occasional cases appearing in other parts of the world.
