Details of the Outbreak and City Response
Legionnaires’ disease is caused by the bacteria Legionella, which thrives in warm water systems such as cooling towers, plumbing, and fountains. The outbreak was first reported last week on the Upper East Side, with several confirmed cases and additional suspected ones. The NYC Department of Health has been investigating water sources in the area, focusing on cooling towers linked to buildings in the vicinity.
City officials have issued advisories to building owners to inspect and disinfect water systems. The outbreak has prompted increased testing and monitoring across the affected neighborhoods. The connection to Central Park was confirmed after health officials identified cases with exposure in or near the park, prompting the warning to visitors.
While the exact source remains under investigation, authorities emphasize that Legionnaires’ disease is not contagious person-to-person but can be contracted through inhalation of contaminated water droplets.
“We are actively investigating the source of this outbreak and have issued advisories to protect the public. Visitors should be aware of symptoms and seek medical care if needed.”
