Officials in New York City said they were monitoring a suspected case of monkeypox, as an outbreak of a disease rarely detected outside of Africa was confirmed in more countries.

The patient in New York was receiving care at Bellevue Hospital, where city health officials said they had performed preliminary tests to confirm whether the person had monkeypox. Globally, 37 cases have been confirmed, and 71 are under investigation in countries where monkeypox isn’t endemic, the World Health Organization said.
