(WGRZ-TV) -- The New York State Department of Health (DOH) has confirmed with Channel 2 that two people in Niagara County have died from Legionnaire's disease.

The Department of Health (DOH) wrote by e-mail, "it's important to note that both individuals had underlying health conditions."

The deaths come at the same time the Niagara County Health Department is investigating eight Legionellosis cases in the community.

A cooling tower at Eastern Niagara Hospital in Lockport recently tested positive for high levels of Legionella (exceeding 1,000 CFU/mL), according to the Niagara County Department of Health. However, there are other cooling towers in the area also being investigated, and as a result, the DOH says that currently, "There is no evidence to date that establishes a link between Eastern Niagara Hospital and the cluster of cases in the community."

Carolyn Moore, Director of Community Relations at Eastern Niagara Hospital, said that recently completed testing at ENH showed negative results for Legionella.

Legionnaire's disease is serious type of pneumonia, or lung infection, according to the Centers for Disease Control and Prevention (CDC).
