(CNN)Canadian public health officials say a rapidly spreading variant likely has now replaced the original Covid-19 virus in many parts of the country, and new variants are making younger people sicker and sending more to the hospital.
“This isn’t the news any of us wanted, but hospitalizations are surging, ICU beds are filling up, variants are spreading and even people who had convinced themselves they didn’t need to be concerned are getting sick,” Canadian Prime Minister Justin Trudeau said at a news conference Tuesday, adding this is a “very serious” third wave of the pandemic. Trudeau made a pointed appeal to young people, urging them to “stay home” as younger Canadians are getting sicker in this third wave. Intensive care unit admissions are up 18% in the past week alone, and the new variants are placing a “heavy strain” on hospital capacity, the Public Health Agency of Canada said.Coronavirus and travel: Everything you need to know “With increasing rates of infection, we are seeing a greater number of younger adults with Covid-19 being treated in hospital,” said Dr. Theresa Tam, Canada’s chief public health officer. She added that more than 15,000 variant cases have been detected so far, the vast majority of them the B.1.1.7 variant first detected in the United Kingdom.

The order will be in place from April 7-18, according to the guidance issued Tuesday, and may be extended.”Current circumstances require that difficult decisions must be taken locally to protect all those in our school communities, including students, teachers and staff,” Toronto Public Health said. British Columbia has moved to close the Whistler ski resort and further restrict gatherings in the province, which is now also coping with an outbreak of the virus among NHL hockey players with the Vancouver Canucks.California says it will fully reopen in June, citing falling Covid-19 case ratesThe province of Alberta also confirmed it was dealing with new clusters of cases involving the P.1 variant. This week, Canada surpassed 1 million Covid-19 cases since the pandemic began. Tam called that milestone a “stark reminder” of everything Canadians have been through. While the B.1.1.7 variant has now likely become the dominant variant in Canada, Tam said her team is also keeping a close eye on a significant outbreak of the P.1 variant, first detected in Brazil and now surging in some western Canadian provinces. Monday, British Columbia’s health minister said the number of cases of the P.1 variant in his province almost doubled over the Easter holiday weekend.”The most transmissive variants of Covid-19 are ultimately going to take over,” Adrian Dix said in a Monday update.
