The Upper East Side’s Legionnaires’ disease outbreak has now caused over 20 hospitalizations, officials say.
The cluster, which is being investigated by NYC’s Health Department, continues to grow daily in the area.
Here’s what to know as of Friday, July 10.
Upper East Side Legionnaires’ Disease Cluster
The city’s health department is still investigating a community cluster in Carnegie Hill and Yorkville, two neighborhoods in the Upper East Side. The affected zip codes are: 10028, 10128, and 10075.
Officials emphasized that residents can still do everyday activities with their water supply, like drink tap water, shower, cook and use AC units at home.
People are at risk of getting Legionnaires’ disease if they breathe in water vapor contaminated with the bacteria. If multiple people become infected within a neighborhood, a typical source would be a cooling tower, hot tub or spray fountain, NYC Health wrote on its website. Mark Levine, the city’s comptroller, said this current cluster of cases is from a contaminated cooling tower, and not a water system. In another post, Levine said that “it takes two weeks or so to grow legionella samples in the lab so we will not get the location of contaminated towers right away.”
