Ninety-two people have been diagnosed with Legionnaire's disease since July 25 when the cluster of cases was first identified in Central Harlem, according to the latest numbers from the New York City Health Department.

Health officials in New York City say an outbreak of Legionnaires’ disease in Central Harlem has grown to 90 cases, including three deaths.

In the five ZIP codes affected by the outbreak, the number of inspections fell more dramatically than in the rest of the city.

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.
