On Aug. 4, 2025, the New York City Health Department provided an update on the investigation into a community cluster of Legionnaires’ disease in Central Harlem (ZIP codes 10027, 10030, 10035, 10037, and 10039) and bordering communities. Fifty-eight people have been diagnosed with Legionnaires’ disease since July 25, 2025 and two people have died.

The remediation required by the Department has been completed for the 11 cooling towers with initial positive screening results showing the presence of Legionella pneumophila, a type of bacteria that causes Legionnaires’ disease.

People living or working in the area with flu-like symptoms, such as cough, fever, chills, muscle aches, or difficulty breathing should contact a health care provider immediately. It is especially important for people at higher risk — including those ages 50 and older, cigarette smokers, and people with chronic lung disease or compromised immune systems — to get care if they have symptoms.
