changing the name

Mpox was given the name monkeypox because it was first identified in colonies of monkeys in 1958. It was not discovered in humans until 1970. However, last year’s worldwide outbreak of the disease had nothing to do with primates. All identified transmissions are attributable to human-to-human transmission.
