Virus sickens 200 in Yellowstone and Grand Teton
(Reuters) - Two of America's premier national parks, Yellowstone and Grand Teton, warned visitors on Wednesday about a gastrointestinal illness that has sickened at least 200 people at the start of the summer tourist season.
The rare health advisory, tied to a suspected outbreak of the highly contagious norovirus, comes in the early weeks of a season that drew about 6 million people to the parks last year.
The warning advises visitors to the parks in northwestern Wyoming to wash their hands to stem the spread of the virus, which causes a flu-like ailment whose symptoms include stomach pain and vomiting, park officials said.
They have required businesses such as restaurants and lodging facilities to increase cleaning and disinfection of all public areas and have asked potentially infected park workers to isolate themselves until they have been symptom-free for at least 72 hours.
