Coronavirus: What's happening in Canada and around the world on Sunday

The latest:

• Why were some isolation periods shortened for the vaccinated?

• Omicron's transmissibility is driving calls for better masks.

• As provinces limit PCR testing, should Canadians be able to report rapid test results?

Ontario hospitals are feeling the brunt of soaring COVID-19 case counts as the virus rips through the province at record speed and infects high numbers of patients and health-care workers.

The situation has become so serious that some hospital networks are reporting that hundreds of their staff members have tested positive for the virus, are symptomatic or are in isolation after an exposure.

Kevin Smith, president and CEOof Toronto's University Health Network, says those factors combined have resulted in at least 100 staff absences per day as the highly transmissible Omicron variant drives case counts to unprecedented highs across the province.

"There aren't health-care workers growing on trees, so it's a very, very limited supply, and they're in hot demand everywhere," Smith said in a telephone interview.

Ontario parents anxious as other provinces delay back-to-school return

Ontario parents are anxious and frustrated about a lack of information as some other provinces delay the return to school amid skyrocketing COVID-19 case counts.

The number of staff unable to work at UHN's five facilities in recent weeks including Toronto General, Toronto Western and Princess Margaret hospitals is higher than what the facilities experienced in previous waves of the virus.

The high number of unavailable staff comes as Smith has noticed fewer critically ill people entering hospital from the virus. This is despite the fact that Public Health Ontario reported 16,714 new infections on Sunday and a record 18,445 cases on Saturday, noting both figures are considered underestimates.

The number of active cases in the province has now crossed the 100,000 mark.

While Smith said staff are managing the current volumes well, he worriesabout the situation changing.

"I'm obviously worried that as we get people engaged in larger and larger amounts of social interaction, including in schools and other environments, there is risk of additional and significant spread," he said.

"Our hope is that populations like those wouldn't require hospitalization, but we have to be prepared for the fact that they will because in other countries, we're seeing kids' admissions going up."

To prepare, Smith is urging Health Canada to immediately approve Paxlovid, Pfizer's antiviral COVID-19 pills, for emergency use.

He is also looking at redeploying staff to areas most in need and pulling hospital doctors and nurses back from vaccine clinics, where they can be replaced with other regulated health-care workers.

West of Toronto, similar moves are being considered at Hamilton Health Sciences, which runs Hamilton General Hospital.

Earlier in the week, organization president and CEO Rob MacIsaac asked vacationing, part-time and casual staff to pick up extra hours in exchange for premium pay up until Wednesday.

He made the appeal as the new year began with at least 411 of his staff in isolation at home and numerous outbreaks across his hospital sites.

"Unfortunately, the Omicron variant has set us back several steps," MacIsaac said in a news release. "Consequently, we are once again facing immense pressures around hospital occupancy and staffing."

Hospitals were experiencing an increase in patients who tested positive for COVID-19. Many were admitted due to medical conditions not linked to the virus, he said.

More than 100 in-patients at his hospitals were positive for COVID-19 as of Dec. 31, and 13 were in intensive care units.

Doris Grinspun, head of the Registered Nurses' Association of Ontario, responds to news that the Ministry of Education would be suspending the reporting of COVID-19 cases in schools and child-care centres.

Emergency department volumes were simultaneously exceeding pre-pandemic volumes and seeing an increase in the number of patients arriving to the hospitals by ambulance on a daily basis.

On top of asking health-care workers to pick up extra shifts and hours, MacIsaac said his organization would turn to "extraordinary measures," such as ramping down "procedural and scheduled care" beginning on Tuesdayto divert resources to areas of "greatest need."

He also said he would soon share more information on plans to call back asymptomatic staff with a negative rapid antigen test, who are currently isolating at home, as well as efforts to deploy workers from ambulatory areas to support in-patient care.

What's happening across Canada

With testing capacity strained,experts say true case counts are likely far higher than reported. Hospitalization data at the regional level is also evolving, with several provinces saying they will begin to report more precise data that separates the number of people in hospital because of COVID-19 from those in hospital for another medical issue who also happen to test positive for COVID-19.

In British Columbia, Pacific Coastal Airlines an operator that serves smaller communities throughout the province'sWest Coast and Interior has suspended operations for two days due to Omicron cases at its operational control centre at the South Terminal of the Vancouver International Airport.
