A deadly Legionnaires' disease outbreak in New York City has set health and community leaders on a campaign to educate the public on ways to prevent the bacteria from growing and spreading. Health leaders hit the streets of Harlem for a third straight day Friday with fliers urging people to take precautions as the number of infections continues to rise.

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.
