Fifth Fatality Reported in New York City Legionnaires' Disease Outbreak

New York City health officials reported a fifth death associated with the Legionnaires' disease outbreak that has affected more than 60 people in the past month. The health department confirmed the presence of Legionella bacteria in 34 cooling towers across 33 buildings and said all identified towers are being cleaned and disinfected.

No new cases have been reported in the past ten days, and eight patients remain hospitalized while 56 others have been discharged after treatment. The city is addressing a total of 82 cooling towers in 80 buildings as part of its response.

The outbreak has been traced to building cooling systems, despite recent regulatory changes that increased testing requirements earlier this year. The Guggenheim Museum noted that an external contractor conducts monthly testing and treatment of its cooling tower.

Attorney Jory Lange, who represents victims of a previous Legionnaires' outbreak in Harlem, said the recurrence is unacceptable and called for stricter enforcement of existing regulations.

Health Commissioner Dr. Alister F. Martin said the department’s rapid response after the first confirmed cases helped save lives and that an ongoing investigation will inform updates to policies and procedures aimed at preventing future incidents. Following the Harlem outbreak, the city expanded its legionella inspection team, hiring additional water ecologists and supervisors, and has conducted nearly 1,600 cooling tower inspections in the first half of the year, a 35% increase over the same period last year.
