Doctors, epidemiologists optimistic schools won't close during 4th wave

Several Ottawa-area health experts remain cautiously optimistic schools won't close during the pandemic's fourth wave as COVID-19 infections and outbreaks caused by the contagious delta variantclimb.

Increasing vaccination rate even further will help keep kids in class, experts say

Several Ottawa-area health experts remain cautiously optimistic schools won't close during the pandemic's fourth wave as COVID-19 infections and outbreaks caused by the contagious delta variant climb.

As of Saturday, there were eightactiveoutbreaks in schools and other child-care settings in Ottawa.

While 81 per cent of eligible Ottawans are fully immunized against COVID-19, doctors and epidemiologists say to prevent closures thatprovedinescapable during the last school year, the number will have to rise higher.

Ottawa schools likely to remain open despite fourth wave, epidemiologist says

Doug Manuel, senior scientist with The Ottawa Hospital, says hes optimistic that schools will be able to remain open during the fourth wave of the pandemic by relying on measures already in place, such as cohorting, mask use and physical distancing.

"It's avoidable if we really ratchet up vaccinations, so that all of the adults that these kids get in contact with are vaccinated," said Raywat Deonandan, an epidemiologist and associate professor atthe University of Ottawa.

For now,COVID-19 vaccines are only available to those born in 2009 or earlier, leaving younger elementary students vulnerable to not just contracting the disease but also spreading it through the community.

Along withboosting vaccination rates,Deonandan told CBC Radio'sOttawa Morningthere are also"mitigation tools" that should be adopted, includingbetter ventilation systems, higher-quality N95 masks and a more rigourous rapid testing regime.

Staff, as well asstudents Grade 1 and up, must already wear masks in most indoor settings, whileself-screening will be required before coming intoschool facilities.

All four of Ottawa's school boards have also mandated masks for kindergartners. The province has also directed school boards to come up with vaccination policies for teachers and other staff.

"We still don't think that kids are going to get as sick as adults," said Deonandan.

"But this is a numbers game. And delta is so transmissible that it's going to infect so many people that the raw numbers of individual children who get seriously sick will be higher, even though the proportion might not be."

'I'm confident'

School outbreakssimply reflect COVID-19transmission patterns in the wider community, said Dr. Robert Cushman, acting Medical Officer of Health for the Renfrew County and District Health Unit.

Even so, Cushman said schoolshave proven capable over the course of the pandemic of containing outbreaks and limiting the spread of the disease.

His health unit had the "notoriety" last year of being the first in Ontario to close a school due to COVID-19, but Cushman said there were only two subsequent outbreaks.

"These kids have suffered enough their schooling, their mental health, their social lives," hesaid.

"I know we're dealing with the delta variant now, which we weren't dealing with a year ago. But I'm confident that the schools can do as good a job as any place in keeping the virus at bay."

Should be enough warning

Ontario has taken a more conservative approach than other jurisdictions when it comes to COVID-19 rules around schools,according to Dr. Doug Manuel,a senior scientist with TheOttawaHospital who models local COVID-19 numbers.

That should give officials time to react if a spike in cases appearson the horizon, he said.

"I think if we're going to see school start running into problems, it's probably going to be in other places [first] more than in Ottawa," Manuel said.

"And we'll be able to adjust our efforts to keep schools open."
