MORRIS PARK - A new cluster of Legionnaires' disease cases has emerged in the Bronx, according to the city's Health Department.

Officials say the cluster is centered around the Morris Park neighborhood and is unrelated to this summer's outbreak.

So far, seven people are in the hospital, officials say.

The borough president's office says three of the seven patients live in the area. The other four either work there or frequently visit.

The first case was reported on Sept. 21, officials say.

The Health Department tested 35 cooling towers over the weekend in an attempt to find the source.
