(JACKSON, WY) – A Norovirus that originated in Yellowstone National Park earlier this month has been linked to at least 200 illnesses. Officials say nearly 150 employees at Yellowstone and Grand Teton national parks caught the stomach flu from a group of tourists in the Mammoth Hot Springs area. Area health officials say it’s one of the biggest outbreaks they’ve seen. Norovirus is easily spread by contact with an infected person or contaminated surfaces.
