CHICAGO (AP) — Illinois is reporting one new case of a rare stomach illness, bringing the total number of cases in the state to five.
Illinois Department of Public Health spokeswoman Melaney Arnold says health officials are still investigating the source of the bug and have been unable to link the illness to any food source.
An outbreak of the same infection in Iowa and Nebraska has been tied to salad mix supplied by a Mexican farm.
In Illinois, none of the people infected has required hospitalization. The cases of cyclosporiasis were reported in Montgomery, Jo Daviess, Lake, Sangamon and McHenry counties.
The most recently reported case is in McHenry County. That person got sick the third week of July.
Health officials believe the Sangamon County patient acquired the infection in Iowa.
