FAIRVIEW, Ore -- Swimming, boating and other water activities were again allowed at Fairview's Blue Lake Park Wednesday, after an eight-day closure due to norovirus.
At least 25 people got sick last week after swimming in the lake. Several tested positive for norovirus.
The information suggests that someone had a fecal accident in the lake and introduced the virus, said county spokeswoman Julie Sullivan-Springhetti.
County health officials said the water is now safe.
But precautionary signs at the park will ask visitors to report any vomiting or diarrhea starting within one to two days of swimming in the lake.
The signs will also remind visitors how to avoid spreading illness: Don t go in the lake if you re feeling ill and children under age 5 are not allowed in the lake.
