# 76 UES Buildings Test Positive For Legionella: See New List

> **Open Intelligence Dossier** · First detected: 2026-07-15 03:07 UTC · Category: Health

## Executive Summary
Seventy-six buildings on the Upper East Side, including the Met and Guggenheim, have tested positive for Legionella bacteria in a growing NYC outbreak.

## Intelligence Brief
A significant health alert has emerged on the Upper East Side of New York City as 76 buildings have tested positive for Legionella, the bacteria responsible for Legionnaires' disease. According to reports from ABC7 New York and Patch, these facilities have been ordered to clean their cooling towers to mitigate the risk. The list of affected sites is extensive, featuring high-profile institutions such as the Metropolitan Museum of Art and the Guggenheim Museum. Other entities flagged in the outbreak include several elite prep schools and various banks. The scale of the issue has expanded rapidly, with Gothamist noting that the number of buildings testing positive has more than doubled since the preliminary findings were first released. Multiple news outlets are tracking the progression of the outbreak with a focus on public health infrastructure.


PIX11 and the New York Post highlight the diversity of the impacted locations, ranging from cultural landmarks to educational facilities. Spectrum News NY1 and NBC News report that while the number of positive tests is high, the rate of new cases is beginning to slow. This deceleration coincides with the city's ongoing efforts to mandate the cleaning of cooling towers across the affected area. The Independent has specifically emphasized the impact on world-famous museums, underscoring the public nature of the sites where the bacteria were detected. Contextual data provided by Spectrum News NY1 indicates that the outbreak has reached 63 cases specifically within the Upper East Side. The presence of Legionella in cooling towers is a critical concern because these systems can aerosolize the bacteria, allowing it to be inhaled by people in the vicinity.


The rapid increase in positive tests suggests a widespread environmental contamination issue within the district's water management systems. Despite the identification of 76 positive buildings, AP News reports that the exact source of the outbreak remains unclear, meaning the city is still working to determine how the bacteria spread so extensively across different types of properties. Moving forward, the primary focus remains on the remediation of the flagged buildings. Monitoring will continue as NYC oversees the cleaning of cooling towers to ensure the bacteria are eradicated. Future updates will likely depend on whether the slow-down in new cases reported by NBC News and AP News continues or if further buildings on the Upper East Side test positive. Coverage does not yet specify a timeline for when all 76 buildings will complete their cleaning protocols or if additional sites outside the initial list will be ordered to undergo testing as the city continues to investigate the source.
