La Crosse health experts warning of nasty stomach bug spreading

Flu numbers haven’t seen their peak yet but Norovirus is on the rise.

The stomach illness, that lasts from one to four days, features symptoms of vomiting and diarrhea and usually has people thinking the worst.

Erin Passe with Mayo Health System in Holmen says the biggest symptom to watch out for is dehydration, especially if you have had a hard time keeping anything down for about four days.

At that time it’s probably time to be checked out.

Symptoms usually come on within 12-24 hours after being exposed. Passe says it’s easy to catch, as it’s an airborne virus.
