In late 2023, Middlesex and Union counties in New Jersey reported a significant spike in Legionnaires’ disease cases, drawing concern from local and state health officials.

Investigations into the source of exposure are still ongoing.

Middlesex and Union Counties Outbreak Overview

According to the New Jersey Department of Health, 21 residents of Middlesex County and 20 residents of Union County tested positive for Legionella pneumophila, the bacteria that causes Legionnaires’ disease. Testing was performed after individuals developed pneumonia-like symptoms between August 3 and October 24, 2023.

Legionella bacteria are commonly found in natural water sources, but they can become a health risk when they grow and spread in man-made water systems such as building plumbing, hot water tanks, cooling towers, air-conditioning systems, and showerheads. Inhaling small water droplets containing the bacteria can lead to serious respiratory illness, especially among the elderly or immunocompromised.

So far, health officials have not been able to determine a definitive environmental source for the outbreak, though investigations are ongoing. Efforts are focused on tracing water systems in the affected counties to identify possible contamination points.

Public Health Response

The New Jersey Department of Health is working closely with county officials to investigate the outbreak and limit further infections. Acting Health Commissioner Dr. Kaitlan Baston emphasized the importance of early diagnosis, urging residents who experience pneumonia-like symptoms—such as cough, fever, and difficulty breathing—to seek medical evaluation right away.

Health officials note that the risk to the general public remains low, but vigilance is key to reducing the spread of the disease. Residents, especially those in high-risk groups, are encouraged to stay informed and alert to any symptoms.
