NYC Health Department Investigates Legionnaires’ Disease Cluster in Upper East Side

The New York City Health Department is investigating a cluster of Legionnaires’ disease cases in the Upper East Side neighborhoods of Carnegie Hill and Yorkville. Two people have tested positive for the illness, and officials are currently testing local cooling towers to identify the bacterial source.

What are the symptoms of Legionnaires’ disease?

The New York City Health Department is asking residents who have lived, worked, or visited the Upper East Side since late June to monitor their health. If you experience flu-like symptoms, you should contact a healthcare provider immediately.

According to the health department, primary symptoms include:

• Fever
• Cough
• Difficulty breathing

While the disease can be fatal if not treated in a timely manner, the department noted that the illness is not contagious between people. Legionnaires’ disease can typically be treated with antibiotics.

Who is at the highest risk for infection?

Certain populations face a higher risk of contracting the illness and experiencing severe complications. The health department has identified the following high-risk groups:

• People aged 50 and older
• Cigarette smokers
• Individuals with chronic lung disease
• Immunocompromised individuals

How is the Legionella bacteria transmitted?

Legionnaires’ disease is typically transmitted through water supplies contaminated with Legionella bacteria. These bacteria often find favorable conditions in specific types of infrastructure and equipment.

Common sources of contamination include:

• Cooling towers
• Plumbing systems
• Whirlpool spas and hot tubs
• Humidifiers
• Condensers in large air conditioning systems

As part of the current investigation, health officials will begin sampling and testing all cooling towers in the affected area. If a cooling tower tests positive for the bacteria, building owners will be required to perform a full remediation.

How does this compare to the Harlem outbreak?

This investigation follows a significant Legionnaires’ outbreak that occurred in Harlem last summer. The scale of the Harlem event provides context for the potential impact of urban water-borne illnesses.

According to official data from the Harlem outbreak:

• 114 people were sickened
• 90 people required hospitalization
• 7 deaths were officially recorded

However, the death toll in Harlem remains a point of contention. The Rev. Al Sharpton and lawyer Ben Crump previously claimed that nearly 20 people may have died during that outbreak due to misdiagnoses, which would be nearly three times the official count. In the current Upper East Side cluster, health officials report there have been no deaths associated with the cases.

Is it safe to use air conditioning during the heat wave?

Yes. Despite the ongoing investigation into the Upper East Side cluster, the health department stated it remains safe to use air conditioners, cooling centers, and city facilities. This remains vital guidance as city residents rely on these resources during the current extreme heat wave.
