Two people have died following a Legionnaires’ disease outbreak on Manhattan’s Upper East Side, according to the New York City Health Department. As of Saturday, officials confirmed 72 total cases in the area, with nine individuals remaining hospitalized. The city reports a sustained decline in new diagnoses as remediation efforts in local buildings continue.
Status of the Upper East Side Outbreak
The cluster of cases, primarily centered in the Carnegie Hill and Yorkville neighborhoods, prompted an immediate response from city health officials. Dr. Alister Martin, the city health commissioner, stated that the agency’s strategy of testing and building-wide disinfection has effectively neutralized the source of exposure. According to the Health Department, every building identified with an initial positive test result has completed mandatory cleaning of its cooling towers.
Did you know?
Legionnaires’ disease is not contagious and cannot be contracted by drinking water. It is a form of pneumonia caused by inhaling water vapor containing Legionella bacteria.
Understanding Legionella Transmission
While the city has ruled out plumbing system failures, the bacteria typically colonizes hot water systems. Residents inhale the mist during routine activities like showering. The New York City Health Department confirms that the bacteria is not spread through air conditioning units themselves, though cooling towers are often the primary site for bacterial growth if not properly maintained.
The following groups remain at higher risk for complications if exposed:
- Individuals over the age of 50
- People with weakened immune systems
- Smokers
- Individuals with chronic conditions, including heart disease, lung disease, liver disease, or diabetes
Public Health Guidance and Next Steps
City officials urge residents in the affected neighborhoods to maintain their normal daily routines, including using tap water for cooking, bathing, and drinking. The city has explicitly stated that the water supply itself is safe.
Pro tip: If you have lived, worked, or visited the Upper East Side since late June and develop symptoms such as fever, cough, or difficulty breathing, contact a healthcare provider immediately. The disease is treatable with antibiotics if caught early.
