A Legionnaires’ disease outbreak on the Upper East Side has now been linked to five deaths and 82 confirmed illnesses, according to city health officials. The latest fatality raises the toll in an outbreak that has prompted a broad public health response.
Officials also said live Legionella bacteria were found in 34 cooling towers connected to the investigation. The city reported that all of those towers have since been cleaned and disinfected as part of efforts to limit further exposure.
Legionnaires’ disease is a serious form of pneumonia caused by Legionella bacteria, which can spread through contaminated water droplets. In outbreaks like this one, cooling towers are often closely examined because they can help disperse bacteria into the air.
Health authorities are continuing to track confirmed cases tied to the Upper East Side outbreak while monitoring whether the cleanup steps reduce the risk. The focus remains on containing the spread and identifying any remaining sources linked to the illnesses.
