The city released a few new details about the victims of a Legionnaires' disease outbreak at a Loop Marriott hotel, saying the eight people who contracted the illness ranged in age from 49 to 82.

A city spokeswoman also said seven of the eight victims live outside of Illinois. But the city declined to give further information, citing privacy concerns.

Two of the eight people who contracted Legionnaires', neither of them Illinois residents, have died. CBS-TV in Chicago reported that one of those who died was a Florida physician who was initially diagnosed with pneumonia. The Tribune was not able to confirm that report.

The outbreak occurred among guests who had stayed at the JW Marriott, 151 W. Adams St., between mid-July and mid-August.

Because Legionnaires' is caused by high concentrations of Legionella bacteria, which is found in water, the hotel closed parts of its spa and drained its pool, whirlpool and fountain. The Chicago Department of Public Health said in a statement Monday that there is "no ongoing health risk at the hotel." Marriott has cooperated with the investigation, officials said.

The first three cases of Legionnaires' tied to the Marriott were reported last week. At the time there had been no reported fatalities. That changed Monday, when officials announced five additional diagnoses and two deaths.
