Health officials want to hear from anyone who has vomiting and diarrhea.

Health officials say that an illness outbreak over the Fourth of July weekend may be linked to Lake Minnetonka.

Hennepin County Public Health says it's investigating "multiple reports" of sicknesses possibly associated with the "Big Island" area of the lake.

Big Island is a hugely popular venue for Fourth of July celebrations, and the county now wants to hear from anyone who was in the Big Island area who have symptoms including diarrhea and vomiting.

At this time, no source of the illness has been identified.

"If you have experienced recent vomiting and/or diarrhea and were in that area around the July 4th, please call our disease investigation phone number to report symptoms," the county health board said.

Those with symptoms should call 612-543-5230.
