The Kitsap Public Health District (KPHD) has confirmed the virus affecting those who visited Horseshoe Lake County Park was norovirus. All human stool samples tested were positive for the same type of norovirus, a highly contagious virus that causes symptoms of stomach pain, nausea, diarrhea and vomiting.

The park remains closed while KPHD awaits lake water test results from the Centers for Disease Control (CDC) in Atlanta. The CDC’s test will determine if the virus is still present in the park’s swimming area. The decision to reopen the park will not be made until results are available from the CDC.

The decision to reopen the park will not be made until results are available from CDC which won’t be until tomorrow. More than 260 people have reported symptoms after visiting the lake between July 10 and  July 13.

Kitsap County Parks & Recreation estimates that up to 2,500 people visit the park during hot summer weather.
