Data experts say 6th wave of COVID-19 not yet in B.C., but urge caution as cases expected to rise

Experts say while a sixth wave in the province is unlikely in the immediate future, masks and vaccines are important as the virus still poses a risk.

Layers of protection like vaccines and masks should still be used, according to experts

As Ontario and Quebec declare a sixth wave of COVID-19, experts say B.C. will probably not see a new wave in the near future. However, they caution that we still need to use layers of protection, including masks and vaccines.

Daniel Coombs, a math professorat the University of British Columbia who specializes in disease modelling and epidemiology, said a sudden surge in cases is unlikely to happen at the moment.

"I don't think any of us are predicting a very big wave at this point, nothing like what we saw around Christmas," he said in an interview.

Coombs said the number of hospitalizations, which had been decreasing, appears to have levelled off over the past week.

He predicts cases will rise slightly as public health restrictions ease, but he does not foresee a steep increase in cases anytime soon.

"I don't think it's a time to panic at this point and to see rapid changes in public health policy," he said.

Experts continue to urge caution

Horacio Bach, an assistant professor in the division of infectious diseases at UBC, also said a sixth wave is unlikely to happen soon, noting the number of hospitalizations inB.C. isnot growing as rapidly as Ontario and Quebec.

However, as immunity from vaccines fades over time, Bach said people still need to be careful.

"The level of antibodies after six months of your last dose starts to go down very fast," Bach said in an interview.

While Bach said asixth wave is not likely in the immediate future, he emphasized that the pandemic is ongoing and could change course at any moment. He expects cases to increasesomewhat due to mask mandates being lifted.

"Although [another wave] can happen at any time we still have the virus," Bach said.

Bach recommends continuing to use masks, avoiding crowds, and spending time in ventilated areas whenever possible.

BA.2 subvariant in B.C.

Caroline Colijn, a COVID-19 modeller at Simon Fraser University,believes B.C. will see a sixth wave, but not yet.

"I think we have often been somewhat behind Ontario and we have similar things going on. We have BA.2, we've reopened, we've gone back to school, we're dropping mask mandates," Colijnsaid in an interview on CBC's The Early Edition.

She said the amount of COVID-19 detected in wastewater has reached a plateau over the last few weeks.

However, with the spread of the more contagiousOmicron subvariant BA.2 in combination with B.C.'s easing of restrictions, Colijn expects cases to rise.

"We know BA.2 is here and probably is going to be the majority of COVID soon or is already," said Colijn.

B.C.'s Human Rights Commissioner Kasari Govender wrote a letter to Provincial Health Officer Dr. Bonnie Henry calling for the return of mask mandates.

Govender said in an interview with Robyn Burns on CBC's All Points West that the inconvenience of mandating masks must be weighed against the dangers of not mandating masks, particularly for those who are immunocompromised.

"I think we have to keep our gaze focused on who is the most vulnerable among us, whose rights are most at stake here," said Govender.

Govender said lifting the mask mandate not only poses a health risk to immunocompromised people, but itfurther isolates them from accessing spaces where masks are no longer mandated.

"There will be a day where we don't have to wear masks anymore, but that day is not here yet," said Govender.

Govendersaid she has not yet received a response from the Ministry of Health.
