With influenza back after a two-year lull, this unusual flu season may offer clues for how COVID and influenza will impact each other in the years ahead, with one theory suggesting these two rival viruses could ebb and flow.
The European Commission said Wednesday that between 60 and 80 per cent of the European population was estimated to have contracted COVID-19, a rate comparable to an American estimate this week, as the highly transmissible Omicron variants have pushed infection rates up.
Canada’s COVID-19 immunity landscape has completely transformed since the emergence of Omicron with new estimates suggesting that almost half of the population has been infected.
