Over 30 confirmed sick in outbreak linked to Lake Minnetonka party spot

Health officials updated the situation on Tuesday.

More than 30 people have reported falling sick after spending time on Lake Minnetonka over Fourth of July weekend.

Hennepin County Public Health officials are investigating an apparent outbreak linked to the Big Island area of the lake, which is a popular spot for Fourth of July partying.

In an update on Tuesday morning, the county's epidemiology manager Dave Johnson said more than 30 people have reported vomiting and diarrhea since spending time on the lake, many of them in the Big Island area.

The county meanwhile has received almost 100 calls in response to the apparent outbreak since the news broke on Monday evening.

The symptoms, he says, suggests a water or food exposure, with some even having to seek medical attention due to the onset of dehydration.

The county is continuing its efforts to find the source for the outbreak, with those reporting illnesses interviewed in an attempt to pinpoint the cause.

"We're asking them about: were they in the water, were they swimming, did they potentially accidentally ingest some water," Johnson said, per MPR.

Samples taken from sick individuals are currently undergoing testing, while lake water is also being tested for pathogens.
