The Legionnaires' disease outbreak in Harlem has been traced to 12 cooling towers, including several at city-run buildings, officials said.

Announcement of the latest death comes just hours after city officials identified 12 cooling towers in 10 Harlem buildings that tested positive for Legionnaires' disease.

The outbreak in New York City began in July, which affected dozens of people with severe Legionnaires' disease. The health department confirmed that 17 others are hospitalized as of Friday.
