Four people have died and 76 cases have been identified during a Legionnaires’ disease outbreak centered in Manhattan’s Upper East Side. While health officials report no new cases in over a week and believe the source of the bacteria has been eliminated, the investigation into specific contaminated cooling towers remains ongoing.
Outbreak Scope and Medical Response
The cluster of Legionnaires’ disease has primarily affected residents within the 10028, 10075, and 10128 ZIP codes. Public health officials have confirmed 74 cases associated with the cluster, while ABC7 New York reports a total of 76 cases since the outbreak was first identified.
The severity of the illness has required intensive medical intervention for many patients.
“He was intubated and on a respirator, also bedside dialysis,” attorney Ron Ketter said. “Intravenous antibiotics and I think they were even monitoring his brainwaves.”

As of the most recent updates, seven to eight patients remain hospitalized, while 51 individuals have been discharged. Health Commissioner Dr. Alister F. Martin addressed the fatalities, stating, Out of respect for their personal privacy, we will not be releasing any additional information about their passing.

Investigation of Cooling Towers and Environmental Sources
Legionella bacteria, which causes the severe form of pneumonia known as Legionnaires’ disease, thrives in warm, stagnant water. City officials have focused their investigation on the cooling towers that comprise the air conditioning systems of large buildings in the affected Manhattan neighborhoods. One such tower, located at the Metropolitan Museum of Art, tested positive for the bacteria.
Despite these findings, officials believe the risk to the public is subsiding. Dr. Martin noted that the city has not identified any individuals with new symptoms for more than a week and stated, We believe the source of exposure has likely been eliminated due to our aggressive remediation and enforcement efforts.

The city’s enforcement strategy involves mandatory draining and disinfecting of any cooling tower that returns a positive test result. Officials have pledged to hold property owners accountable for any failures to comply with public health laws. Meanwhile, the family of the 88-year-old veteran has signaled intent to pursue legal action against the owner of the cooling tower eventually identified as the source of the outbreak.
Public Health Guidance and Legislative Oversight
City leadership continues to emphasize that the municipal water supply remains safe for drinking, bathing, and cooking. Officials also maintain that the use of air conditioning units is safe for the general public.
Citing the previous year’s outbreak in Harlem—which resulted in seven deaths and over 100 illnesses—local representatives are pushing for systemic changes.

For residents who spent time in the affected ZIP codes, the Health Department advises monitoring for flu-like symptoms, which can manifest up to 14 days after exposure. Those who develop such symptoms are encouraged to seek medical attention promptly. Updated information regarding the status of the investigation is available through the official Health Department website.
