The first human case of monkeypox—a rare zoonotic virus that can transmit from animals to people—was recorded in the Democratic Republic of Congo in 1970. Since then, the disease has become endemic in parts of West Africa, although outbreaks have been known to occur in other places, such as the United States in 2003 and now in over 60 non-endemic countries. This timeline was a running account, gathered in real-time, of key events in the 2022 outbreak as they unfolded from May 2022 to January 2023. As of January 20, this timeline is not being updated.
