According to a statement issued by Marriott on Tuesday, the Chicago Department of Public Health has alerted the JW Marriott Chicago that three recent guests of the hotel have been diagnosed with Legionnaires’ Disease, a type of a pneumonia. The hotel responded immediately with an investigation in cooperation with the CDPH. On the agency's advice, the hotel has drained and closed its fountain, hot tub and pool. Marriott also is notifying employees and guests who stayed at the hotel from July 16 through Aug. 15, 2012. Currently, CDPH believes there is no health risk to guests or employees staying at the hotel.

Legionnaires’ Disease is contracted by breathing in a warm mist or vapor contaminated with the Legionella bacteria; it is not spread from one person to another. Those who have questions about this particular case or believe they might have been exposed are encouraged to call the CDPH special hotline at (312) 746-4835. For questions regarding the hotel, call Marriott Customer Care at (866) 211-4610.
