A cluster of Legionnaires’ disease in the Upper East Side neighborhoods of Carnegie and Yorkville has prompted a New York Department of Health outbreak investigation.
Between July 2 and July 6, 2026, cases have increased ten-fold!
Since discovery of initial cases, New York City Health Department officials have been warning residents in the area to monitor themselves for symptoms and report them immediately.
How are people exposed to Legionnaires’ disease? What are the symptoms? What should you do if you get sick?
Here’s what we know so far about Legionnaires’ disease in the Upper East Side of New York City!
On July 2, 2026, New York City Health Department announced a cluster of illnesses involving Legionnaires’ disease in the Upper East Side.
A press release indicated that “the NYC Health Department has launched an investigation into a likely community cluster of Legionnaires’ disease in the Upper East Side neighborhoods of Carnegie Hill and Yorkville (zip codes 10028 and 10128).”
At the time, two people were diagnosed with the deadly lung infection and “confirmatory results for other potential cases” were pending. As of July 6, 2026, 23 cases have been reported. At least 17 have been hospitalized. No deaths have been reported so far.
As part of this active investigation for Legionnaires’ disease in the Upper East Side of New York City, sampling and testing all cooling tower system water in the area is underway.
In the past, community clusters have been caused by Legionella bacteria spreading through the outside air through mist produced by cooling towers. Specific wording in press releases and Public Safety Announcements indicate the Department believes this is the case in this illness cluster.
The initial press release described Legionnaires’ disease a “a type of pneumonia caused by breathing water vapor containing Legionella bacteria in the outside air.” A neighborhood notice also explained that “this is not an issue with any building’s plumbing system” and that “it is safe for you to drink water, bathe, shower, cook, and use your air conditioner.”
In fact, they explained, “continuing to use your air conditioner is especially important when the city is experiencing extreme heat and temperatures reach dangerously high levels.”
To get a better hold on this cluster of Legionnaires’ disease in the Upper East Side, a Health Alert was issued to health care providers, advising them to consider Legionnaires’ disease diagnosis with patients presenting “compatible symptoms.”
Additionally, community outreach will be conducted in the area over the weekend to raise awareness.
New Yorkers are advised that any adult with flu-like symptoms, fever, cough, or difficulty breathing and has been in the affected area since late June should seek medical attention right away.
Legionnaires’ disease is caused by inhaling Legionella bacteria. These microscopic germs typically live in natural water environments like lakes, streams, and rivers. They become a problem to human health when they find their way into our water systems.
According to the Center for Disease Control and Prevention (CDC), 1 in 20 people exposed to Legionella bacteria will become sick. Around 1 in 10 will die from complications. The mortality rate increases to 1 in 4 when Legionnaires’ disease is acquired during a stay at a healthcare facility.
While New York City Environmental Investigators are testing cooling towers, there are other types of water fixtures that can also spread Legionnaires’ disease.
Things like:
These water fixtures create a mist or spray fine particles in the air.
Aerosolized particles allow Legionella bacteria to go airborne where an unsuspecting victim can breathe them in.
New Yorkers who work, live, or have visited the Upper East Side neighborhoods are urged to monitor themselves for symptoms.
Symptoms to look out for include:
Other symptoms may include:
Most people begin feeling sick between two and 14 days after exposure. However, it can take longer for symptoms to appear in some cases.
Anyone can become sick with Legionnaires’ disease if exposed. However, some people with certain risk factors are more likely to become sick if exposed and experience more severe illness if infected.
Common risk factors include:
If you believe you are sick with Legionnaires’ disease, call your health care provider immediately. Accurate diagnosis and prompt treatment increases recovery time.
If you have been diagnosed with Legionnaires’ disease it is also a god idea to get advice from a Legionnaires’ disease lawyer.
This illness is preventable with basic maintenance required by local environmental and health authorities. Lapses in required maintenance leave people vulnerable to illness.
