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.

Three people in central Harlem have already died from legionnaires’ disease, according to the NYC Health Department.

Officials said Monday night there has been an uptick in cases in the Legionnaires' disease cluster in Central Harlem.
