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.

The cases are most likely linked to a cooling tower in central Harlem, health officials said. More than 60 people have fallen ill, including three people who have died, from Legionnaires’ disease in New York City over the past several weeks, according to the city’s health department.
