Overview
- The New York City Health Department is investigating a likely community cluster in the Melrose and Morrisania sections after five confirmed cases and one linked death were identified in ZIP codes 10451 and 10456.
- Community health workers have begun door‑to‑door canvassing and multilingual outreach while health teams carry out case interviews and environmental follow‑up.
- City crews have collected samples from local cooling towers and will require building owners to clean and disinfect any towers that test positive for Legionella.
- Confirmatory lab results for other suspected cases are still pending, and officials urge anyone who lived, worked, or visited the area with fever, cough, or breathing trouble to seek medical care because early antibiotic treatment is effective.
- Legionnaires is a form of pneumonia caused by Legionella bacteria that spreads when people inhale contaminated water vapor from building systems, and this South Bronx cluster follows a larger Upper East Side outbreak earlier this summer.
