A Legionnaires' disease outbreak in Manhattan's Upper East Side has reached 60 cases, but new diagnoses are slowing, health officials reported Tuesday. The city has identified traces of the bacteria in dozens of buildings, including the Metropolitan Museum of Art, but has not yet pinpointed the source.
Core Facts & Immediate Action
No deaths have been reported, though 49 patients required hospitalization, with 34 discharged. City data show two new cases diagnosed from samples taken Sunday and Monday, down from as many as 11 per day earlier. Health Commissioner Dr. Alister Martin called the slowdown "an encouraging sign."
Deeper Dive & Context
Inspections and Testing
Cooling towers on 76 buildings tested positive for Legionella bacteria, according to the city's Department of Health. Cooling towers, used for building refrigeration, are a common source of Legionnaires' disease when bacteria-laden vapor is expelled. The outbreak is concentrated in three ZIP codes: 10128, 10028, and 10075.
Symptoms and Vulnerability
Symptoms include fever, chills, fatigue, headaches, and diarrhea. High-risk groups include people over 50, smokers, vapers, and those with weakened immune systems or underlying conditions like diabetes or lung disease. There is no vaccine or preventive medication, and masks do not offer protection.
Public Response
City Council Speaker Julie Menin criticized the Health Department for insufficient transparency, though no further comment was provided by her office. The CDC notes that about 1 in 10 Legionnaires' cases are fatal, though no deaths have occurred in this outbreak.
Broader Context
New York City sees hundreds of Legionnaires' cases annually, but this outbreak is notable for its clustering in a specific area. Officials advise residents in affected ZIP codes to monitor for symptoms.
