ottawa – canada’s top doctor says the country is seeing the feared surge in omicron cases and is warning people to keep their contacts down during the holidays because “the jury is still out” on the new variant’s severity.dr. theresa tam said omicron cases, which first arose in south africa and then spread to europe, were taking increasing hold here. she said there were 900 identified cases of the variant on monday, but that likely represented just the tip of the iceberg.“the cases of the omicron variant are increasing rapidly, which is something that we probably anticipated would happen as we look towards other countries,” tam said in an interview with the national post on tuesday.she said so far omicron cases in canada have been mostly mild, but they have also been in age groups that have had mild cases throughout.“the jury is still out on that front,” she said. “our cases have also been symptomatic, but mild, some are asymptomatic, but the average age is actually still quite young.”ontario’s chief medical officer, dr. kieran moore, echoed those findings at a press conference tuesday.he said of the 4,600 ontarians confirmed to have omicron, only 15 were admitted to hospital.“now, admittedly, that’s in a much younger population that’s gotten omicron. they’ve gotten it through social activities. they’re in the 20 to 30 age range, which has a low risk of adverse events associated with covid in general,” he said.more than 75 per cent of the people hospitalized across the pandemic were over 50 years old.in total, there were just over 10,000 new cases reported on monday with about seven per cent of tests coming back positive. there were also 13 new deaths. a week ago, on dec. 13, there were just over 4,000 cases per day, but so far the number of hospitalizations has not risen dramatically.on dec. 10, the public health agency of canada forecast omicron could cause a steep rise in cases towards the end of the month, with more than 12,000 cases a day if the new variant takes hold. tam said unfortunately canada is on that path.“that is the trajectory that i think we’re essentially following. the only way to change that is, of course, to reduce contract rates,” she said.tam said there were some encouraging signs from south africa and the u.k. about the severity of the disease, but much was still unknown. south africa’s population is younger than canada’s and many people there have previously contracted the virus. the omicron variant was only discovered in november and has spread rapidly around the world since.several provinces have encouraged people to have smaller holiday gatherings and ontario and quebec have put restrictions on certain businesses. tam said what concerned her about holiday gatherings was the potential for more seniors to be exposed to the virus.“what we don’t want to see is this virus going into the older age groups,” she said.
