Scientists at the Center for Disease Control and Prevention (CDC) are tracking multiple cases of Monkeypox that have been reported in several countries that don't normally report Monkeypox, including the United States. Risk to the general public is low, but you should seek medical care immediately if you develop new, unexplained skin rash (lesions on any part of the body) with or without fever and chills, and avoid contact with others. 

For more information about Monkeypox, please visit the NJDOH website:
