Special Olympics illnesses caused by stomach flu virus
DES MOINES, Iowa -- Samples from people who became ill during the Special Olympics USA National Games this week have tested positive for a virus that causes stomach flu, the Iowa Department of Public Health said Saturday. Some people were quarantined.
At least 30 people were treated Friday for vomiting, nausea and diarrhea. The health agency said norovirus is a common cause of viral gastroenteritis, also known as stomach flu, and outbreaks are normally associated with food and water.
