The Omicron variant continued to cause a record number of COVID-19 cases in several provinces, but a new study in Ontario has suggested that people infected with the variant are significantly less likely to be hospitalized or die than those with Delta .

In the study, Public Health Ontario compared cases of Omicron with symptoms that appeared between November 22 and December 17 with cases of Delta and found that after adjusting for vaccine status and region, the risk of hospitalization or death was 54% lower with Omicron. .

The agency said Omicron appears to be the first dominant variant to show a decrease in severity, but warned that due to its higher transmissibility, “the absolute number of hospitalizations and the impact on the healthcare system will likely be significant, despite a possible reduction in severity. “

Provinces across the country have seen the number of cases surge in the wake of Omicron, prompting some to change or expand health restrictions.

Ontario and Quebec both recorded new highs for new infections on Thursday. Ontario has reported 13,807 new cases of COVID-19 and Quebec has reported 14,188.

The Quebec government research institute said its modeling predicts “significant growth in new hospitalizations and the consequent occupancy of regular and intensive care beds over the next three weeks.”

He said his models show there could be between 1,600 and 2,100 COVID-19 patients outside of intensive care units (ICUs) over the next three weeks. The institute said that could include between 300 and 375 intensive care patients during that time. The most dire scenarios – 2,100 regular COVID-19 patients and 375 intensive care patients – would exceed anything recorded in previous waves of the pandemic.

Quebec on Wednesday said vaccinated healthcare workers who tested positive for COVID-19 could be allowed to return to work after seven days if they show no symptoms and workers exposed to COVID-19 by people other than limbs of their household no longer automatically need to insulate.

Manitoba and Ontario have said they are considering similar measures to avoid overwhelming their own health systems.

British Columbia said it would bring students back in January on a phased approach, with staff and students whose parents are health workers, as well as those who need extra support, returning to class on January 3 or 4. All other students will return to school on January 10.

Manitoba, Alberta and British Columbia set new case records on Wednesday. Alberta more than doubled its number of active cases in one week, while recording its largest single-day increase in new infections.
