22 Jul
Summary
- Five people have died in a Legionnaires' disease cluster on Manhattan's Upper East Side.
- At least 82 cases were identified, with 34 contaminated cooling towers found.
- Health officials believe aggressive testing and cleaning have eliminated the exposure source.
As of July 21, 2026, a cluster of Legionnaires' disease on New York City's Upper East Side has resulted in five fatalities. Health officials have confirmed at least 82 cases within this outbreak, with eight individuals currently hospitalized and 56 having been discharged.
The investigation pointed to cooling towers in the neighborhood as the source, identifying Legionella bacteria in 34 towers across 33 buildings. These contaminated towers and affected buildings have undergone cleaning. Results for an additional 140 tested cooling towers are anticipated within the next week.
NYC Health Commissioner Dr. Alister F. Martin stated that rapid and aggressive strategies have likely eliminated the source of exposure. Notably, no new cases have been diagnosed in six days, and no new symptoms have been reported in over ten days, suggesting the situation is under control. Legionnaires' disease is a serious pneumonia caused by Legionella bacteria, typically contracted by inhaling contaminated water droplets from sources like cooling towers.
