A Penobscot County man has tested positive for monkeypox.

It’s the second case of the virus to be confirmed in the state following a York County man whose case was reported July 22, according to the Maine Center for Disease Control and Prevention.

The Maine CDC did not release any additional details about the individual, citing patient privacy.

Maine has received enough doses of the monkeypox vaccine Jynneos for 311 people. The vaccine will be made available to any close contacts.

The Maine CDC advised anyone who believes they have been exposed or have developed unexplained lesions to contact their doctor for evaluation, testing, and referral for vaccination.

Monkeypox is a rare disease in the same family of viruses that includes smallpox. The virus is transmitted by close contact with a symptomatic patient, including physical, skin-to-skin contact, such as sex, according to the Maine CDC.

Symptoms include rashes, sores and a flu-like illness. Monkeypox can be painful and disfiguring, with serious cases requiring hospitalization. But it is rarely fatal, according to the Maine CDC.

Mainers can protect themselves against infection by avoiding close contact with anyone who appears to have monkeypox-like rash; sharing food, utensils and cups used by an infected patient; handling bedding, towels and clothing used by someone who has been infected; and to wash their hands often with warm water and soap or using an alcohol-based hand sanitizer.  

The virus has been present in New England since at least May 18, when  the first case was confirmed in Massachusetts. The virus was confirmed to be in New Hampshire in late June.

As of July 29, there have been 5,189 cases of monkeypox across the United States, according to the U.S. Centers for Disease Control and Prevention.
