The Chicago Department of Public Health (CDPH) is investigating two laboratory-confirmed cases of Legionnaires’ disease in two individuals who both stayed at Embassy Suites located at 600 North State Street in Chicago. Both patients have been treated and are recovering.  At this time, it is not known whether the Embassy Suites was the source of the bacteria that caused the two people to become sick. Potential exposure sites are being sampled and hotel management is cooperating fully with the investigation. There is no immediate risk to the public. Legionnaires’ disease is a serious type of pneumonia. People can get Legionnaires’ disease by breathing in small water droplets containing Legionella bacteria. Symptoms may include fever, cough, shortness of breath and severe headache. If you have experienced these symptoms within two weeks of staying at the Embassy Suites at 600 North State Street, contact your health provider. At CDPH’s recommendation, Embassy Suites has closed all water features while testing is underway and thorough disinfection is being performed. This will greatly reduce the risk of Legionnaires’ disease, if any Legionella was present. Once exposed to Legionella bacteria, disease risk may be increased among individuals who are 50 years or older, who smoke cigarettes, or who have certain medical conditions, such as a weakened immune system.   Anyone with further questions or concerns can contact CDPH at 312-746-7425.
