Multiple reports of illness are being investigated by state health officials, which may be associated with the “Big Island” area of Lake Minnetonka over the Fourth of July.

Experts at Hennepin County Public Health officials are working with Minnesota Department of Health to determine the type of illness, FOX9 reported. As of Monday evening, July 8, no source has been identified.

Those who are sick have reported symptoms including diarrhea and vomiting, the county said. Officials are testing fecal matter from those affected in order to determine if the illness is food-borne, water-borne, or something unrelated.

If you have experienced recent vomiting and/or diarrhea and were in that area around the July 4th, please contact the disease investigation team at 612-543-5230.
