Six people have now died from an outbreak of Legionnaires' disease in Central Harlem, according to the city's Department of Health.
The DOH said Thursday there have now been 111 confirmed cases of the disease, with seven people currently hospitalized.
The outbreak was identified on July 25, with cases recorded in ZIP codes including 10027, 10030, 10035, 10037 and 10039.
Legionnaires' disease is a type of pneumonia that is caused by Legionella bacteria, which grow in warm water and spread through building water systems. The city's outbreak has been linked to cooling towers, which use water and a fan to cool buildings.
People usually develop symptoms — a cough, fever, headaches, muscle aches and shortness of breath — between two days to two weeks after exposure to the bacteria, according
