New Omicron subvariants that can evade immunity better than previous strains are being detected in more countries around the world — including Canada. These subvariants are emerging at a time when Canada's health-care system is already under strain as flu season is fast approaching. "That means it's playing a different game, it's evolving in different ways and that is to masquerade from our immune system." "The stress on the health-care system potentially with XBB from what we're seeing with Singapore right now is scary." Chief Public Health Officer of Canada Dr. Theresa Tam takes part in a videoconference during a news event on the COVID-19 pandemic.
