The Washington State Department of Health has the cause of the "intestinal illness" that broke out at a recent cheerleading competition in Everett: norovirus.

OLYMPIA — Testing at the state Public Health Laboratories confirms that norovirus caused hundreds of illnesses during and after the February 4 state high school cheerleading tournament. Norovirus is typically transmitted person-to-person.

The number of people reporting they suffered vomiting and diarrhea during the event or in the days after is now 229. At least 33 have reported seeking medical care though there have been no overnight hospital admissions. The numbers are expected to grow as state health officials receive answers from surveys that were sent to participants and families.

The Washington State Department of Health is leading the disease investigation, working with local health partners and the Washington Interscholastic Activities Association (WIAA), sponsor of the event in Everett.

As a survivor of a bout or two with norovirus, all I can say is: gross.
