Norovirus

Norovirus has been found in samples from an outbreak at a Nampa Middle School two weeks ago. The Southwest District Health Department confirms two stool samples came back positive for the virus.

It started two weeks ago when children at Lone Star Middle School came down with vomiting and diarrhea. By that Thursday, more than 150 kids stayed home sick. The next day, close to 500 students missed class.

Health officials in southwest Idaho say norovirus is what sickened dozens of people at Eagle Island State Park last weekend.

The Central District Health Department says the likely source is a sick person who swam in the water or became sick at the park.

Department spokeswoman Kimberly Link says the virus can spread from one person to another through recreational water, food and direct contact.

She says human waste and vomit are the main sources of norovirus.

Idaho health officials are trying to determine what is causing the gastrointestinal illness that has affected commercial and private rafters on the Middle Fork of the Salmon River, as well as fire personnel.

Mike Taylor, an epidemiologist with the Eastern Idaho Public Health District, tells the Idaho Statesman that river guides have fallen ill and a Forest Service weed control crew had to be flown out after getting sick.
