Ask CBC: COVID-19 and holiday gatherings

Dr. Brian Conway, infectious disease specialist and medical director for the Vancouver Infectious Diseases Centre, answers a CBC audience member's question on whether to invite an unvaccinated person to a holiday gathering.

While the new coronavirus variant omicron appeared to be very transmissible, the right response was to be prepared, cautious and not panic, the World Health Organization's (WHO) chief scientist Soumya Swaminathansaid Friday.

WHO has urged countries to boost health-care capacity and vaccinate their people to fight a surge in COVID-19 cases driven by the omicron variant, saying travel curbs could buy time, but were not the only answer.

"How worried should we be? We need to be prepared and cautious, not panic, because we're in a different situation to a year ago," Swaminathan said.

While the emergence of the new variant was unwelcome, she said the world was much better prepared than it was atthe start of the COVID-19 pandemic, given the development of vaccines.

Much remains unknown about omicron, which was first detected in southern Africa last month and has been spotted in at least two dozen countries. Parts of Europe were already grappling with a wave of infections of the delta variant before omicronemerged.

"We need to wait, let's hope it's milder but it's too early to conclude about the variant as a whole," Swaminathan said of the new variant.

"Delta accounts for 99 per centof infections around the world. This variant would have to be more transmissible to out-compete and become dominant worldwide. It is possible, but it's not possible to predict."

WHO's top scientist said the omicron variant seemed to be causing three times more infections than experienced previously in South Africa, meaning "it does seem to be able to overcome some of the natural immunity from previous infection."

Vaccines did appear to be having some effect.

"The fact that they're not getting sick that means the vaccines are still providing protection and we would hope that they would continue to provide protection," Swaminathan said.

She said the health organization is "preparing for all scenarios," which could include an additional booster dose, particularly among some age groups or vulnerable sections of the population, or a modified vaccine.

WHO warns 'bit of a roller coaster' coming on information about omicron

The World Health Organizations emergencies director, Mike Ryan, says the transparency around rapidly emerging data on the coronavirus variant omicron is empowering but recognizes how unsettling it is to be hearing bits of information in real time.

Dr. Mike Ryan, executive director of the WHO's emergency program, said later Fridaythat information about the variant willsoon be flowing in as scientists learn more. He urged people to "stay centred" and not "go to the extremes of any analysis."

"There was a time when scientists would look at all this data and nobody in the public would know, and eventually, a month later there would be a result," he said during a question and answer session about omicron. "That's not how the world works anymore everything is happening in real time."

Ryan said that shift offers some real benefits around transparency and community empowerment, butit can also be "unsettling" to people because firmanswers aren't available right away.

"We've got to get used to living in that world where getting the real evidence and answers is slightly behind getting all the data and all this kind of unlinked information," he said.

"We all live with that uncertainty."

What's happening across Canada

An Ontario infectious disease specialist says there is evidence that testing all travellers before and after they arrive in Canada will identify most cases of COVID-19 coming into the country.

McMaster University physician Dr. Zain Chagla is highly critical of Canada's plan to try toslow the spread of the new omicron variant by only banning travellers from 10 African nations, and said testing, not travel bans, is a less harmful and more effective mitigation strategy.

Friday afternoon, York Region in Ontario reported one positive case of the omicron variant, bringing the total to13 cases nationally: seven in Ontario, four in Alberta, one in Quebec and one in B.C.

The omicron variant is driving a sharp increase in COVID-19 cases across South Africa. Scientists believe the variant is more transmissible, and may even bypass acquired immunity in some people who have recovered from COVID-19.

InEurope, more regions of Russia have made COVID-19 vaccines mandatory for those 60 and over as the country tries to control infections andkeep the omicron variant at bay.

Authorities in the northern region of Komi said Friday people in that age group are required to get fully vaccinated by Feb. 1. The Omsk region in Siberia introduced a more stringent timeline Thursday that obligates those 60 and olderto get their first dose by Dec. 24 and their secondby Jan. 15.

Russia has struggled to get cases down amid low vaccination rates and poor compliance with public health measures. Only about 40 per centof Russia's populationhave been fully vaccinated.

Meanwhile,the prevalence of COVID-19 infections in England rose to around onein 60 people in the week ending Nov. 27, Britain's Office for National Statistics saidFriday, noting the increase was attributed to the dominant delta variant rather than newly identified omicron. The prevalence was up from 1 in 65 reported the previous week, the ONS said.
