New York, NY — The Legionnaires’ disease outbreak in Central Harlem has claimed its fifth life, with over 100 confirmed cases across five ZIP codes in Upper Manhattan, the New York City Health Department reported on Tuesday.
Outbreak Statistics and Hospitalizations
Since the outbreak began on July 25, health officials have recorded 108 cases in Central Harlem — a historically Black neighborhood. The most recent death, reported on August 18, was linked to the cluster after review by health officials.
As of August 19, 14 patients remain hospitalized, while the department continues to monitor the affected areas: ZIP codes 10027, 10030, 10035, 10037, and 10039.
“Based on epidemiological evidence, remediation efforts have been effective as new cases continue to decrease,” said Dr. Michelle Morse, acting commissioner of the city health department, in a statement on X. “The Health Department is continuing our investigation.”
The department emphasized that the risk remains low for most residents but urged anyone living or working in the area with flu-like symptoms to seek medical care immediately.
Cause Linked to Cooling Towers
Investigations have traced the outbreak to cooling towers in Central Harlem. These devices use fans and water to cool buildings and can harbor the Legionella bacteria, which causes Legionnaires’ disease.
- On August 14, testing confirmed 12 cooling towers in the area had positive results for Legionella bacteria.
- Remediation of these towers has been completed, and ongoing monitoring continues to ensure public safety.
“Any cooling towers with initial positive results for Legionella bacteria have completed the treatment required by the Health Department. We are continuing to monitor and let buildings know if additional treatment is needed,” the city health department stated.
Officials clarified that the outbreak is not linked to building plumbing or hot and cold water supply, and people may continue to use air conditioning and other water appliances safely.
Understanding Legionnaires’ Disease
Legionnaires’ disease is a severe form of pneumonia caused by inhaling Legionella bacteria from contaminated water, according to the Centers for Disease Control and Prevention (CDC). Symptoms, which may appear up to 14 days after exposure, include:
- Cough
- Fever and chills
- Headache and muscle aches
- Shortness of breath
“Legionnaires’ disease can be effectively treated if diagnosed early, but New Yorkers at higher risk, like adults aged 50 and older and those who smoke or have chronic lung conditions, should be especially mindful of their symptoms and seek care as soon as symptoms begin,” said Dr. Morse.

Legionnaires’ disease cannot spread from person to person and is typically treatable with antibiotics, though roughly one in ten patients may die due to complications.
Historical Context of Outbreaks in NYC
The Central Harlem cluster is now the largest Legionnaires’ outbreak in the city in a decade. Previous outbreaks include:
- 2015 South Bronx: 138 cases, 16 deaths linked to a single cooling tower
- 2022 Highbridge, Bronx: 30 cases in a residential cluster
Officials warn that warmer, more humid temperatures contribute to increased cases nationwide.
