The New York City Health Department is investigating a community cluster of Legionnaires' disease in parts of the Bronx, specifically Melrose and Morrisania (ZIP codes 10451 and 10456). One person has died and five people have been diagnosed with the disease so far. Officials are urging residents with flu-like symptoms to contact a healthcare provider and are testing cooling towers in the affected area for contamination. Update (NYC Health Department, 20.09.2026, 09:30): The case count of five diagnoses and one death is current as of September 10. The department will direct remediation of any cooling towers that test positive for Legionella bacteria. Residents who visited the area since late August and have flu-like symptoms should seek immediate medical attention. Update (NBC New York, 24.09.2026, 20:20): The cluster has grown to 23 cases and two deaths. Live Legionella bacteria have been confirmed in cooling towers at seven buildings. All ten implicated cooling towers, including those with pending results, have already been cleaned and disinfected. Update (makefoodsafe.com, 24.09.2026, 20:20): A separate Legionnaires' disease outbreak is under investigation at the Evanston Hilton Garden Inn in Illinois. Legionella bacteria were confirmed in the hotel's hot tub water system, leading to the closure of the pool and hot tub areas since September 2 for remediation. Guests experiencing pneumonia like symptoms within two weeks of visiting the hotel should consult a medical provider.
