The results of other possible cases of Legionnaires' disease are currently pending, the health department said.

Legionnaires’ disease, a type of pneumonia, is caused by bacteria called Legionella that thrive in warm water environments, like cooling towers and plumbing systems.

Last summer, Legionnaires' disease sickened more than 100 people in Harlem and killed seven people, after 12 buildings with cooling towers tested positive for Legionella bacteria.

Legionella can grow in cooling towers, which create cold air by cycling warm air through water, creating a warm, humid environment within the system.

The disease spreads by inhaling contaminated mist, but is not contagious from person-to-person, officials said. Drinking tap water, showering, and using the air conditioner are all safe, officials said.

Upper East Siders experiencing flu-like symptoms — such as fever, cough, or difficulty breathing — should contact a healthcare provider immediately.

All cooling towers in the area are actively being tested and sampled for the bacteria by the health department, officials said. Any cooling towers that test positive will be fully remediated, officials said.
