Jackson, Wyo. • A norovirus outbreak that sickened more than 100 people at Grand Teton and Yellowstone national parks appears to have subsided.
Officials from both parks say the number of confirmed cases of the gastrointestinal bug has returned to near normal levels.
A rash of reports of the illness began in the Mammoth area of Yellowstone in mid-June. Cases were reported at Grand Teton National Park a week later.
The parks and their concessionaires disinfected public areas and quarantine workers who displayed symptoms of the illness.
Chuck Harris is manager at Grand Teton Medical Clinic at Jackson Lake Lodge. He tells the Jackson Hole News & Guide that it was one of the more "atypical" spikes in gastrointestinal illness he has seen in his 29 years working in the park.
