A Legionnaires’ disease outbreak has escalated on Manhattan’s Upper East Side, with 14 confirmed cases reported, according to New York City health officials. The affected areas encompass ZIP codes 10028, 10128, and 10075, including parts of Yorkville and Carnegie Hill. Health officials noted that at least one patient has a connection to the area, either living, working, or having recently visited ZIP code 10075.

People who have spent time around the east side of Central Park, between East 76th Street and East 97th Street, should monitor their health for flu-like symptoms. These include fever, cough, chills, and muscle aches. Such symptoms could indicate exposure to Legionnaires’ disease, a severe form of pneumonia triggered by Legionella bacteria. The disease transmits via inhaling infected water droplets and can be lethal without prompt treatment.

“I want to acknowledge the NYC Health Department’s staff who have been diligently working to keep New Yorkers informed and safe,” stated NYC Health Commissioner Dr. Alister F. Martin.

The investigation is focusing on potential sources of the outbreak. Cooling towers in the area, which can emit mist containing the bacteria, are under scrutiny. Health officials are actively testing these towers to identify any contamination sources.

The outbreak was initially announced when two cases were detected. Following this, the scope of investigation broadened as additional cases emerged. City officials emphasize that the outbreak is unrelated to building plumbing or indoor air conditioning systems. Residents can safely utilize tap water and other domestic utilities.

“We identified the cluster early and took immediate action, temporarily sidelining holiday plans to assist our community,” Martin added.

New York City Mayor Zohran Mamdani reassured residents of the situation and encouraged those with symptoms such as cough or fever to seek medical advice. Updates will continue as new information surfaces.

Last year, another Legionnaires’ disease outbreak in Central Harlem resulted in over 100 confirmed cases. Individuals experiencing symptoms who have been in the Upper East Side area since late June are advised to contact healthcare providers promptly.
