New York City will launch stricter rules for cooling towers after one of the worst Legionnaires’ outbreaks in years broke out in Harlem. The city Health Department plans on ramping up enforcement, penalties and reporting requirements for building water systems that are considered the source of many cases of Legionnaires’ disease.

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 Legionnaires’ disease outbreak in Central Harlem has left 67 people sick and three dead since late July, prompting renewed demands for New York City to overhaul its prevention strategy and address the bacteria from water source to tap.
