Harlem, New York City, experiences another fatal case of Legionnaires' disease. Learn more about the disease's symptoms.
Breaking News: Ongoing Legionnaires' Disease Outbreak in Central Harlem, New York City
A significant outbreak of Legionnaires' disease in Central Harlem, New York City, has been ongoing since late July 2025, resulting in at least 83 confirmed cases and 3 deaths as of early August 2025. The identified sources of the outbreak are 11 cooling towers in the area, all of which have tested positive for Legionella bacteria.
The New York City Health Department is taking swift action to address the outbreak. All 11 cooling towers that tested positive have been remediated and treated with anti-bacterial agents to stop the spread of Legionella. The health department is also continuing to investigate other buildings across multiple ZIP codes in Central Harlem (including 10027, 10030, 10035, 10037, and 10039) to identify additional sources and prevent further cases.
Officials have issued health alerts urging residents—particularly those at higher risk such as people aged 50 and older, smokers, and those with chronic lung or immune conditions—to seek immediate medical care if they develop flu-like symptoms (cough, fever, chills, muscle aches, difficulty breathing). It's essential to note that tap water remains safe for use, indicating the source is localized to cooling towers rather than the municipal water supply.
April McIver, who leads the Plumbing Foundation City of New York, is backing a City Council bill that would expand Legionella testing. The bill aims to prevent similar outbreaks in the future by ensuring a comprehensive approach to water management systems in buildings.
The city has launched an awareness campaign, going door to door in Harlem distributing pamphlets and educating residents about the disease and the importance of seeking early medical attention if symptoms are present.
Acting Health Commissioner Dr. Michelle Morse said, "We are doing everything we can to urgently both test and clean the cooling towers that we think are the source of this Legionella exposure."
Some New Yorkers are worried about the potential spread of Legionnaires' disease. However, it's important to remember that the disease is not transmitted person to person or through drinking water.
It's crucial for everyone, especially those living in the affected zones, to stay vigilant and aware of any flulike symptoms. If you develop such symptoms, contact a health care provider immediately. Early treatment can significantly reduce the risk of complications.
