Third Death Linked to Upper East Side Legionnaires' Disease

New York City health officials announced that a third person has died as a result of the Legionnaires' disease outbreak on the Upper East Side. This tragic loss comes as the number of new cases has seen a substantial decline, leading authorities to believe the source of the cluster has been contained.

City health officials have identified a total of 74 cases associated with this outbreak. While eight patients remain hospitalized, the overall trend indicates a significant improvement, with fewer than one new case per day reported recently. This sustained decrease suggests that the likely source of exposure has been eliminated.

Investigators are pointing to a cooling tower contaminated with Legionella bacteria as the probable origin of the outbreak. Although the specific tower has not been identified, 183 cooling tower systems in affected areas were tested. Legionella genetic material was found in 76 buildings, all of which have since undergone mandatory draining, cleaning, and disinfection.
