New York City’s Department of Health releases a preliminary list of buildings that have cooling towers testing positive for Legionella bacteria, the cause of Legionnaires’ disease, according to multiple outlets. The list includes 31 buildings in Manhattan’s Upper East Side and identifies the Solomon R. Guggenheim Museum among the properties with positive test results. The reports describe the findings as part of the city’s ongoing response to a current outbreak of Legionnaires’ disease. The Health Department is the first to publish such a preliminary set of results, which centers on cooling-tower testing rather than confirmed illness cases tied to specific sites. The outlets do not indicate that the museum or other buildings are definitively responsible for infections, but they note that the presence of Legionella in building systems can increase the risk of disease if it spreads through building water or air-conditioning equipment. The city’s reporting emphasizes the need for further investigation and follow-up testing and measures at the affected properties.
