Third Death in Harlem Legionnaires’ Outbreak Sparks Urgency

UPDATE: A third death has been confirmed in the ongoing Legionnaires’ disease outbreak in Harlem, which has now affected nearly 70 people, according to Mayor Eric Adams. The source of this alarming outbreak appears to be local cooling towers, officials revealed on Wednesday morning.
The outbreak, first detected on July 25, 2023, has rapidly spread across five zip codes in upper Manhattan—specifically 10027, 10030, 10035, 10037, and 10039. The latest figures indicate a significant increase from Monday’s report, which confirmed two deaths and 58 cases. Health officials urge residents in these areas to be vigilant.
“We believe the outbreak is located in Central Harlem coming from the cooling towers,” Mayor Adams stated in a video announcement. “We’re asking those experiencing flu-like symptoms in the area to seek medical attention immediately.”
While Legionnaires’ disease can be deadly, it is treatable if detected early. Health officials emphasized that the disease does not spread from person to person but is contracted through water supplies contaminated with Legionella bacteria. These bacteria can thrive in plumbing systems and cooling towers, as well as whirlpool spas and hot tubs.
The city’s health department has identified the bacteria in 11 cooling towers across the affected areas. Mayor Adams has mandated that building owners conduct full remediation within 24 hours if any source of the bacteria is found.
Authorities report that between 200 and 700 of New York City’s 8.5 million residents are diagnosed with Legionnaires’ disease each year. The last major outbreak occurred in the summer of 2022, resulting in at least five fatalities at a nursing home in Manhattan.
As this outbreak continues to develop, officials are urging the public to stay informed and take precautions. The health department is monitoring the situation closely, and additional updates will be provided as they become available.
For residents in affected areas: If you exhibit flu-like symptoms, seek medical attention without delay. Your health could depend on it.
