President Joe Biden on Sunday said that the recent spread of monkeypox in at least 12 countries are “something that everybody should be concerned about.”

Why it matters: These are the president’s first public remarks about the recent outbreaks, which include a confirmed case in Massachusetts, a person who tested positive in New York and roughly a half dozen other cases being monitored by the Centers for Disease Control and Prevention.

“It is a concern in that if it were to spread it would be consequential,” Biden told reporters at Osan Air Base in South Korea, where he met with troops before heading to Japan on the next leg of his Asia trip.
