It's not here yet, but a new strain of Norovirus could be making its way across Canada.

The virus has been detected in BC, and has been responsible for a substantial increase in gastrointestinal illness reports and outbreaks at health care facilities around the world.

At this point, Toronto Public Health is giving the heads up to healthcare workers and food handlers to prepare for the possible arrival of this new virus.

Norovirus is a gastrointestinal bug that generally leads to diarrhea, vomiting and stomach cramps and is highly contagious.

It can prove fatal in a worst case scenario, to the elderly, those with underlying illnesses and young children.
