What are the symptoms of this type of pneumonia, called Legionnaires' disease, and how do you treat it? Here's what you need to know.

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

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.

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

The source of the illness has not been conclusively identified more than a week after people began getting sick.

A woman diagnosed with Legionnaire's disease described her frightening symptoms amid an outbreak in Harlem that has infected nearly 70 people and led to three deaths. "My body is hurting really bad," said Stephanie Tribble,
