ORLAND PARK (Sun-Times Media Wire) - About 50 people were sickened with possible norovirus after a party Friday night in southwest suburban Orland Park.
The party happened at Orland Chateau at 14500 S. La Grange Rd. in Orland Park, according to Cook County Department of Public Health spokesperson Deanna Durica.
More than 200 people attended the party, and about 50 became ill over the weekend with nausea, vomiting and diarrhea, Durica said. The symptoms are consistent with norovirus, but it has not yet been confirmed.
