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.

Cases of Legionnaires' disease linked to an outbreak in Central Harlem continue to climb. CBS News New York's Alecia Reid spoke to a woman whose sister is hospitalized.

New York City officials gathered Thursday to address the growing concern regarding the cluster of Legionnaires’ disease cases in Central Harlem. As of Thursday afternoon, three people had died of the disease.
