Second death reported in Manhattan Legionnaires' outbreak

The New York City Health Department said a second person died from Legionnaires' disease in the Upper East Side cluster, bringing the death toll to two. The department reported a total of 72 confirmed cases in the Carnegie Hill and Yorkville neighborhoods, with nine patients still hospitalized.

"While we mourn this loss, the data are also encouraging," Health Commissioner Dr. Alister Martin said. "Our aggressive strategy of testing, enforcement, and remediation appears to have stopped the source of exposure. We directed every building with an initial positive test result to immediately clean and disinfect its cooling tower, and every one has completed that work."

Officials have ruled out plumbing issues as the source and emphasized that Legionella spreads through contaminated water vapor, not through air-conditioner units or drinking water. The disease, a form of pneumonia, primarily affects individuals with weakened immune systems, older adults, smokers, and those with chronic health conditions, but it is treatable with antibiotics. Residents and visitors who have been in the affected area since late June and develop flu-like symptoms such as cough, fever, or breathing difficulties are advised to seek medical attention.
