The McLean County Health Department is investigating an outbreak of presumed foodborne infection associated with a chain restaurant in Bloomington, IL. The restaurant has been closed for decontamination as a precautionary measure although an inspection did not reveal deviations from accepted hygienic practices.

According to reports an acute illness occurred on April 7th with 16 individuals reporting sickness of whom 15 were students at the university and who dined at the restaurant together.  Given the report of sudden onset severe vomiting and diarrhea, norovirus is the most likely cause although no specific diagnosis has been disclosed.
