Abstract
AbstractCooling tower systems have been the source of multiple large Legionnaires' disease outbreaks. We report a July-August 2025 outbreak in the Central Harlem area of New York City, with 118 confirmed cases and seven deaths. An investigation was initiated on the day the daily spatiotemporal cluster detection analysis by the New York City Health Department noted eight positive urine antigen test results for <i>Legionella pneumophila</i> serogroup 1. A total of 43 cooling tower systems were sampled by day 3. Whole-genome sequencing analysis suggested that the available clinical isolates were highly related to those from two cooling towers located on the same city block.
