A person under age 18 has tested positive for monkeypox in Maine, the state’s first pediatric case, the Maine Center for Disease Control and Prevention announced Friday.

The state is not releasing any additional information about the person who tested positive, citing patient privacy. Maine CDC is identifying close contacts and making a vaccine available to those who may have been exposed.

This is the third case of monkeypox in Maine, with the two previous cases in adults, one in York County and the other in Penobscot County. Nationally, at least two other states, California and Florida, have confirmed monkeypox in someone under 18.

Monkeypox is a rare disease caused by a virus that causes a rash or sores and can be preceded by a flu-like illness, according to the Maine CDC. It is spread by close, physical, skin-to-skin contact. 

The CDC recommends avoiding close contact with those who have a rash that looks like monkeypox and avoiding contact with objects and materials that a person with monkeypox has used.

The global monkeypox outbreak began in May and there have been 10,768 cases in the U.S.
