@IHME_UW Here's a screenshot of the IHME estimates.
From Dec 23-Apr 1, Canada can expect 6M-24M COVID infections.
Most likely number: 15 million infections. Most will be unreported.
Estimated hospital resource use:
Most likely: 1,418 daily hospitalizations, 362 daily ICU admissions, by Feb 24.
Could be as high as 3,269 hospitalizations, 832 ICU admissions, by Feb 13.
Canada's worst day to date: May 9/21: 1,100 hospitalizations, 271 ICU admissions.
IHME estimates of new COVID-19 deaths in Canada from now to April 1/22.
Somewhere between 10,000-31,000 deaths.
Somewhere between 3K-15K of these deaths will be reported.
Remember, outside Quebec, only ~half of COVID-19 deaths are reported.
Watch QC closely as we go forward.
Finally, if vaccine protection against severe disease has dropped from 90% to 70%, as early South African reports suggest, these future hospitalization and death estimates will be higher.
You'll also note that getting every last person vaccinated, boosted, and ensuring 80% of people wear masks will collectively reduce future severe outcomes significantly.
What's the most important way we can slow spread so that we can get all of this in place?
Social distancing.
I have no idea any more how to explain to people what will happen if we don't modify our behaviour NOW.
Every single person's decisions about this matter. Some of us can NOT socially distance because of work, caregiving, health needs. But MANY of us can.
PLEASE do it NOW.
We need to buy time to ensure new medications are available, to get people vaccinated, boosted, wearing the best masks they can.
If our healthcare workers all get infected too, we are in deep, deep trouble.
Please help us buy time. PLEASE stay home.

1. Data sources, methods are at bottom of linked spreadsheet
2. Estimated vaccine-preventable and breakthrough severe outcomes from July 1, 2021 to present have been subtracted from estimated future totals
3. Estimated future deaths, ICU admissions and hospitalizations are based on age-specific OECD rates for the ALPHA strain, which at this point appears likely "milder" than Omicron.
I know many Canadians now think that Omicron is mild. Please see threads about this linked below.
Here's are estimates of severe BREAKTHROUGH COVID-19 outcomes, by age group, in Canada or comparable OECD countries.
Remember, risk of these outcomes are 7-9X higher in UNVACCINATED people.
These are based on the age-specific OECD infection fatality rates for Alpha (so quite conservative), and assume that vaccine protection vs severe outcomes in double-vaxxed people has dropped from 90% to 70% for Omicron, as per recent South African reports.
They're estimates, but remember that Alpha was "milder" than Delta, and that monoclonal antibodies we use for treatment also look like they're taking a big hit with Omicron. These estimates may be revised up/down, but probably not by huge amounts. They're decent ballparks.
As for doubly vaccinated Canadians 40 and older, especially if your last shot was more than 6 months ago, here are your risks, assuming that vaccine protection from severe outcomes has fallen from 90% to 70% with Omicron.
Omicron may reduce vaccine protection against severe COVID-19 outcomes from 90% to 70%.
If true, this could result in more than 100,000 breakthrough deaths in Canada if everyone is infected.
Get boosted ASAP. Not this weekend. As fast as you can, especially people 40+.
Most of us cannot understand how fast Omicron cases are growing. They will double every 3 days once Omicron is dominant--which will be by the end of this week in Ontario.
Don't just get your booster. IMMEDIATELY start taking precautions to reduce risk of exposure and spread.
And if you're UNVACCINATED, I beseech you--get your first dose immediately. Hospitalizations and deaths will rise exponentially after cases.
If you're 40 and older and unvaccinated, you have a 1 in 17 chance of hospitalization with COVID. You have no time left to wait. PLEASE.
The most recent age-specific vaccination data from @GovCanHealth indicated the Canadian regions with the highest risk for future ICU admissions, deaths and hospitalizations are, in order, AB, ON, NWT, YK, SK, BC, NB, QC, NS, MB, NL, NUV, PEI.
SK 1st dose vax has really sped up.
@GovCanHealth However, even though ON is now a major concern due to slow vaccination in people 50+, I couldn't figure out how to identify the ON regions at greatest risk because provincially reported vaccination rates are so much higher than national rates, especially in older age groups.
Hang on. I'm pulling out the regional data for vax rates among people 80+ in ON PHUs, together with estimated numbers of deaths that will result when unvaccinated people 80+ are infected with SARS-CoV-2. Not if. When.
