Hundreds of people are being checked for norovirus after dozens of dancers fell ill following a competition on the weekend.
The virus hit dancers and their family members after the event which was in Saskatoon and attracted hundreds of participants from dance groups and schools across the province.
"We had kids going down, parents getting sick, siblings [on] Monday and Tuesday," Wendy Spicer, director of the Martin School of Dance in Regina, told CBC News Friday. "They just kept dropping like flies."
Officials from the Saskatoon Health Region say between 250 and 500 people are showing symptoms of the virus.
The dance competition ended on the weekend, but people are still contracting the virus, which is similar to the stomach flu but more intense.
"We've been following up with the dance schools and receiving reports of student illness amongst their dancers and between 25 and 50 per cent of students who attended the dance competition are reporting symptoms," Dr. Julie Kryzanowski, Saskatoon's deputy medical health officer, said Friday.
