A cooling tower at the Guggenheim Museum in New York City tested positive for Legionella bacteria, linking the institution to a citywide outbreak [1].
The discovery connects one of the world's most famous art museums to a public health crisis that has sickened dozens of people across Manhattan's Upper East Side.
Health officials have identified a widespread cluster of Legionnaires' disease cases centered around the "Museum Mile" area [2]. The outbreak, which has seen cases reported since late June 2024 [3], was traced to water-cooling towers where the bacteria proliferate and spread through aerosolized mist.
Citywide testing has revealed that cooling towers at 31 different Upper East Side sites tested positive for the bacteria [4]. The scale of the outbreak has varied across reports, with some data indicating 23 people were sickened [5], while other safety alerts state the number of cases has exceeded 50 [1].
Of those affected, 17 people have been hospitalized [6]. Legionnaires' disease is a severe form of pneumonia caused by the Legionella bacterium, which often thrives in man-made water systems such as large building cooling towers, hot tubs, and complex plumbing [4].
Officials continue to monitor the affected buildings in the Upper East Side to ensure the bacteria are eradicated. The Guggenheim Museum is among the high-profile sites where the contaminated water systems were identified as a source of the pathogen [1].

The involvement of the Guggenheim Museum and 30 other buildings highlights the systemic risk posed by aging or poorly maintained urban cooling infrastructure. Because Legionella spreads through airborne mist, the high density of the Upper East Side increases the likelihood of a localized outbreak scaling quickly across multiple city blocks.
