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.

A recent cluster of Legionnaires’ disease cases in New York City has once again raised alarms in Georgia about this rare illness, recalling the state’s outbreak in 2019. The New York Times reported the Harlem outbreak is linked to contaminated cooling towers in 11 buildings and 70 people have been diagnosed with three deaths reported so far.

The disease is a type of pneumonia caused by the bacteria Legionella, which grow in warm water and can spread in building water systems such as showerheads.
