Legionnaires' Disease

Click here for the latest information from Trenton Water Works: Legionella Mitigation & Updates

Legionella bacteria causes Legionnaires’ disease. In nature, Legionella bacteria live in freshwater and rarely cause illness. Getting sick from these bacteria is rare, but possible when water is aspirated into the lungs. Most healthy people do not get Legionnaires’ disease after being exposed to Legionella. Current or former smokers, those who suffer from lung disease such as COPD, and those who have a weakened immune system have greater susceptibility.

Respiratory Syncytial Virus (RSV)

RSV is a common respiratory virus that usually causes mild, cold-like symptoms. Most people recover in a week or two, but RSV can be serious, especially for infants and older adults. For more information visit the CDC's homepage on RSV and learn about the symptoms and prevention measures.

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.
