Norovirus is spreading at a “higher frequency” than expected in Canada, specifically, in Ontario and Alberta, according to the Public Health Agency of Canada .
Specifically, PHAC noted an increase in Ontario, Alberta and, to a lesser extent, British Columbia, Saskatchewan, Manitoba, New Brunswick, and Newfoundland and Labrador. “People are doing more social things and going on cruises and those kinds of exposures that are risks for getting norovirus,” Hota said.
As of the most recent report on Thursday, there were three outbreaks reported in Toronto health-care institutions. After contracting the illness, it can take 12 to 48 hours to develop symptoms, which are usually at their worst in the first 48 to 72 hours, according to Hota.
