Communicable Diseases

 The Hopewell Township Health Department monitors and serves as a reporting agency for communicable diseases in Hopewell Township, in order to keep our community safe by preventing further spread and to assist patients, and their close contacts, with any questions or concerns.

For information about communicable diseases and additional health topics, visit the New Jersey Department of Health's "A-Z" guide: If you have any questions or concerns, or wish to report an illness, please contact our Public Health Nurse at 609-537-0238.

Scientists at the Centers 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:
