The mysterious stomach bug that has sickened hundreds in about a dozen states has local health officials on watch.
The Illinois Department of Public Health reported one case in Central Illinois confirmed in a person who traveled to Iowa, where many of the cyclospora infection cases have been reported.
There are no confirmed cases in Missouri, where Ryan Hobart is a spokesman for the Missouri Health Department.
"We recommend that Missourians who feel they may be ill or have some of the symptoms, they should contact their health care provider to be examined," Hobart says.
Symptoms of the cyclospora infection include diarrhea, bloating, nausea and other flu like symptoms. No cause has been pinpointed yet, but health experts remind consumers that all fresh produce should be washed before consumed.
