Manitoba's 3rd wave exceeding worst-case projections for intensive care patient numbers, daily COVID-19 cases

Daily COVID-19 case countsand the number of patients with the illness ending up in intensive care units inManitoba areexceeding the province's most extreme projected scenarios for the third wave.

Dr. Jazz Atwal, Manitoba's deputy chief public health officer, unveiled the pandemic modelling Fridaythat the province used to assess the need for itsmost recent lockdown measures.

By all key metrics including a rising test positivity rate, evidence of broad community spread and higher percentages of more infectious variants those projections suggest COVID-19 cases and hospitalizations linked to the illness will keep growing "substantially" in the coming weeks, he said.

Last week, CBC News obtained a leaked copy of a provincial presentation slide that showed modelling forintensive care admissions an updated version of which was included in Friday's presentation.

The leakeddata suggested the province expected thenumber ofCOVID-19 patients in its intensive care units to exceed the height of the pandemic's second wave by the end of the May long weekend, and potentially double again before summer.

Atwal said he thinks case counts in Manitoba will peak sometime next week, but it could take between two and four weeks before intensive care admissions hit their highest numbers ahead of the scenarios outlined in the modellingreleased Friday.

He pointed to people not following public health orders and guidance as the reason behind why Manitoba's numbers have surged above worst-case scenarios.

"What's driving this extreme scenario is people's behaviours. It's about those interactions.It's about not adhering to the orders to [their]fullest degree. It's about not listening to the messaging to its fullest degree," he said at a news conference.

"We have people [diagnosed with COVID-19] who are being honest, who are saying, 'Yes, I went to a bonfire. Yes, I had a sleepover. Yes, six of us got together at someone's house and played video games. Yes, we had a big barbecue.'"

COVID-19 numbers across the board have been trending upward in Manitoba since April 23,Atwal said.Since then, cases alone have been going up by 33 per cent every week, while intensive care admissions have been up by 20 per cent weekly and hospitalizations have increased by about 18 per cent eachweek.

How the next few weeks shake out will depend entirely on how closely people follow Manitoba's pandemic rules and how many do it, he said.

"A best-case scenario is within a week, we've got a plateau. ICU numbers come down [a few weeks after]," Atwal said.

"Now obviously if there is no adherence, we will go down not a very good path. But we are hoping and we are expecting Manitobans to adhere so that our numbers plateau and we limit the impacts on our acute-care system."

Younger patients, worse outcomes

The increase in intensive care admissions is also partly because more contagious coronavirus variants have led to younger, unvaccinated people having more severe outcomes and spending more time in hospital, Atwal said.

"Being young does not make you immune to COVID-19. Being young does not mean you will not have a severe outcome. We have many hospital beds occupied by young people who are otherwise healthy," he said.

Over the last two weeks, about half the COVID-19 patients hospitalized in Manitoba are under 50. Those cases are split evenly between peoplein their 30s, 40s and those under 30, Atwal said.

About 25 per cent of people who land in intensive care with COVID-19 stay longer than two weeks, though some stay as long as seven weeks.

As of midnight, 67 of Manitoba's 117 intensive care patients had been diagnosed with COVID-19, a spokesperson for Shared Health said in an email on Friday afternoon. Fifty of those cases were still active and 12 of those people were under age 40.

Dr. Jazz Atwal, Manitoba's deputy chief public health officer, revealed pandemic modelling Friday that shows how hard the third wave has hit the province, and said younger people are increasingly becoming seriously ill with COVID-19.

Before the pandemic, the baseline capacity for the province's critical care program was 72 patients, the spokesperson said.

Atwal said the province will release its modelling more often in the future to help people better understand Manitoba's pandemic situation. But hestopped short of saying there would have been better compliance with public health orders if the models had been shown to the public earlier.

"It is challenging to say," he said. "Maybe it would have helped in some situations, and in other situations it probably wouldn't have made a difference."

Hours after Manitoba announced people as young as 12 are now eligible to get immunizedagainst COVID-19, Atwal urged people to get their shots as soon as they can.

As of Friday, 49.4 per cent of adults in Manitoba have gotten at least one dose of vaccine, the province's online vaccine dashboard says.

Officials previously said some Manitobanswill be able to start booking second-dose appointments by May 22, though on Friday said thatcould end up happening even earlier.
