Legionnaires’ Disease Cluster Under Investigation in Harlem

Summary:
Health officials in New York City are examining five confirmed cases of Legionnaires’ disease in Central Harlem and surrounding neighborhoods. Water from cooling towers across four ZIP codes is currently being tested.

A group of Legionnaires’ disease cases identified in Central Harlem and adjacent areas is now under investigation by New York City health authorities.

Since Friday, five individuals have received diagnoses, with additional people tested and awaiting their results.

No fatalities have been recorded.

To determine a potential source, officials are collecting and analyzing water samples from cooling tower systems located within ZIP codes 10027, 10030, 10035, and 10037.

City health officials have advised adults who have spent time in the affected region and are experiencing flu-like symptoms or trouble breathing to consult their health care providers.

Legionnaires’ disease is a type of pneumonia and typically presents with fever, chills, muscle pain, and coughing.

Transmission occurs through inhalation of water vapor containing the Legionella bacteria, which thrive in warm water. Authorities have stated that the bacteria are most commonly linked to plumbing networks, whirlpool baths, hot tubs, and sizable air conditioning units.

The illness cannot be transmitted from person to person and is treatable with antibiotics when identified early.

Health officials encourage individuals at increased risk—including smokers, those with long-term lung illnesses, and anyone over the age of 50—to promptly seek medical care if symptoms develop.
