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.

People usually develop symptoms of Legionnaires’ disease around two to 14 days after being exposed. People often get the disease by inhaling mist from contaminated water, but it is not spread from person to person. Symptoms include fever, muscle aches and coughing.

The health department offered five ZIP codes in central Harlem -- 10027, 10030, 10035, 10037, 10039 – that were at the center of the cluster, as officials stressed the disease was airborne and could reach people even outside of the directly affected buildings.
