Four people have died as a result of a Legionnaires’ disease outbreak in Harlem that has sickened nearly 100 people, and officials revealed the cooling towers that tested positive for the bacteria that causes the illness — some of which are at properties owned by New York City,

The deadly Legionnaires’ outbreak gripping Harlem has city officials in hot water — as locals accused them Friday of dropping the ball on life-saving inspections and needlessly slow-walking revealing exactly where the disease hit.

Health officials in New York City say an outbreak of Legionnaires’ disease in Central Harlem has grown to 90 cases, including three deaths.

Announcement of the latest death comes just hours after city officials identified 12 cooling towers in 10 Harlem buildings that tested positive for Legionnaires' disease.
