Last year, a cluster of Legionnaires' disease in Harlem was traced to a cooling tower at Harlem Hospital. 

Legionnaires' disease is a type of pneumonia caused by Legionella, a bacterium that grows in warm water. Complications from the disease can be fatal. The illness causes flu-like symptoms, which means it can be hard to diagnose. Indeed, some of the symptoms — cough, shortness of breath, body aches, and high fever — are similar to the symptoms of COVID-19, which is caused by a virus, not a bacterium. 

The symptoms of Legionnaires' disease usually begin two to 10 days after being exposed to the bacteria but people should watch for symptoms for about two weeks after exposure, according to the CDC.
