Wash your hands! That's what the National Park Service is telling visitors going to Yellowstone and Grand Teton national parks after dozens have become ill in recent weeks.
The warning is due to greater-than-normal reports of gastrointestinal illness in the parks, according to a news release.
Yellowstone employees have reported more than 100 suspected cases of norovirus in the past week. At Grand Teton, there have been 50 suspected cases among employees. Also, 50 visitors went to medical clinics in Yellowstone with symptoms of gastrointestinal illness.
This comes after a tour group arrived at Mammoth Hot Springs on June 7, complaining of stomach flu and other GI symptoms, according to the release. Within 48 hours, numerous employees were complaining of similar symptoms. Some of the employees and visitors tested positive for norovirus.
Norovirus symptoms include stomach pain, vomiting and diarrhea. It is very contagious and is spread through direct contact with an infected person, touching contaminated services and consuming contaminated foods and beverages.
