Health officials confirmed Friday that a fast-acting gut bug known as norovirus is responsible for an outbreak of illness that sickened more than 200 people gathered for a cheerleading championship in Washington state last weekend.
Results of state laboratory tests showed that that the nasty group of viruses caused the short-but-severe vomiting and diarrhea that affected some people who participated in and attended the state championship and Salute to Spirit cheerleading, dance and drill team event held in Everett, Wash. Norovirus is typically spread through person-to-person contact.
Most of the 100-plus people infected with norovirus last month had eaten at a local Subway franchise.
But an investigation by the Blackford County Health Department was unable to determine whether a customer or an employee spread the virus, also known as a stomach bug and food poisoning.
