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.

Some in the area say they were unaware of the outbreak of Legionnaires' disease, let alone the location of problem sites.

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.

City health officials are sounding the alarm as a Legionnaires’ disease outbreak spreads through Harlem, killing two and sickening at least 58 others. The pneumonia-like illness, first detected July 25, has been reported in zip codes 10027, 10030, 10035, 10037 and 10039, as well as in neighboring communities.

Harlem faces a Legionnaires' disease outbreak alongside steep Medicaid cuts, causing concern for health support and funding among residents and local organizations.
