Illinois health officials now report five cases ofa rare stomach illness. The latest case is in McHenry County. Connie Austin is an infectious disease specialist with the state health department. She says more than 400 cases have been reported in 16 states.
"Our numbers are pretty low, which we're pretty happy about. Obviously Iowa and Nebraska were hit the hardest early on. I think we're not hit as hard as other states and hopefully it will remain that way," Austin said.
State officials are still investigating the source of the illness caused by a parasite, but have been unable to link it to any food source. An outbreak of the same infection in other states has been tied to salad mix supplied by a Mexican farm. In Illinois, none of the people infected have required hospitalization.
