The Michigan Department of Health and Human Services released its latest numbers today. As of July, 9, 2026, 44 people reported being hospitalized after seeking treatment.

Cyclosporiasis occurs when a person is infected by a parasite and is spread by food or water contaminated with feces.
It causes frequent watery diarrhea and includes abdominal cramps and nausea among other symptoms. Dehydration can lead to more severe illness.
The public is urged to continue to wash hands and produce thoroughly. Frozen and cooked foods are not linked to the outbreak.
