The Saskatoon Health Region is investigating a gastrointestinal outbreak that happened at a dance competition last weekend.

More than a dozen groups from Saskatchewan and Alberta gathered for The Performer at TCU place.

The region said they were notified that people who attended had symptoms consistent with Norovirus.

“So we’re investigating this now as a community outbreak of gastrointestinal illness,” said Deputy Medical Health Officer Dr. Julie Kryzanowski.

An instructor from Dance Ink studio in Saskatoon said about a quarter of her students and their parents have gotten sick.
