New York City health officials report that Legionella bacteria, which can cause Legionnaires’ disease, has been detected in cooling towers at multiple buildings on Manhattan’s Upper East Side amid an ongoing outbreak. PBS NewsHour and other outlets cite the city’s release of a list of 31 buildings that are ordered to clean and disinfect their cooling towers after positive tests for Legionella. Several well-known cultural sites are included, including the Solomon R. Guggenheim Museum and the Metropolitan Museum of Art, according to reports from Artforum and other sources. The bacteria is associated with warm water systems such as cooling towers. Coverage also notes that the outbreak involves dozens of cases, with New York Post reporting that the number of local cases rises to 59, while stating that no deaths have been reported and that additional testing may identify more infections in the coming days. Across outlets, the key focus is on building-level remediation steps: health officials direct affected properties to disinfect and address the source systems identified in testing, as the city continues monitoring and expanding its list of sites tied to the outbreak.
