COVID: Wear a mask, strengthen yourself against the background of the sixth wave, says Tam

Canada’s Chief Public Health Officer, Dr. Theresa Tam, advises Canadians to continue wearing the mask, regardless of different jurisdictions, as the country sees a resumption of COVID-19 cases.

Speaking to reporters during an update of the pandemic on Tuesday, Tam also stressed the need to step up with a third dose of COVID-19 vaccine to prevent severe outcomes of the disease.

“Let me just emphasize that across Canada, it doesn’t matter where you are, it’s very likely that the Omicron variant, BA.2 subline, will be widely distributed in your community. So no matter where you are in Canada right now, I would advise you to do this booster injection, mask and improve ventilation, “she said.

He added that the disguise mandate could remove individual “guesses”, but acknowledged that provincial public health authorities were trying to promote good habits without imposing them on people.

“I think that in different communities, depending on the context, social cohesion and other variables, each of these policies can work better in different circumstances. But I think people want to see and believe that the population is able to use these layers of protection, “she said.

Asked if the definition of “fully vaccinated” should be changed from two to three doses, Tam said it was an “ongoing discussion” but supported the importance of getting a third vaccine.

“I think the message today is to keep up to date with your vaccination, which includes a booster for all eligible populations, that’s 18 plus and [it] can also be offered to adolescents. So that’s the most important message, “she said.

Since the end of March, there has been a gradual increase in COVID-19 cases across the country. However, officials say this was expected after some provinces lifted public health restrictions, including masking and vaccination proof requirements.

As the testing rate has decreased, local authorities are monitoring the spread of the virus by testing municipal wastewater. At the national level, Tam said employees are trying to make more of this data publicly available.

We are trying to provide this information on wastewater testing sites on a website, but I know we can do more as we begin to escalate the benefits of this tool … Wastewater data currently covers just over 60 percent of population. “We’re trying to do better, to try to get that 80 percent coverage, but that’s not the easiest thing to interpret,” she said.

According to data monitored by, approximately 32.4 million first doses of COVID-19 vaccine were administered, 31.2 million second doses were administered and 18.3 million third doses were administered.

There, he attributes the rather low frequency of intensifying strikes in Canada to the fact that some Canadians may have thought the third shot was unnecessary after the last reduction in cases. She also noted that the National Immunization Advisory Committee still advises those who test positive for COVID-19 to wait three months before receiving an injection.

“So I think some of these factors can affect why we don’t get the level of push we see. I also admit that during the initial efforts to run the incentive campaign, it was a very difficult time when vaccine workers became infected. “We had absences from public health and the health system,” Tam said.
