Something many Canadians don't realize is that we're going through the Omicron wave at the same time or even slightly before the UK--the country we compare ourselves to most.
The UK tests a lot more than Canada per capita BTW, which is why our % test positivity is higher.
Canada is also seeing considerably more ICU admissions per capita than the UK in the Omicron wave, and our per capita ICU admissions are shooting up, whereas UK ICU admissions have been staying relative stable.
In Canada, we should be very careful about assuming we're same as UK
One possible reason for difference in ICU admissions between Canada and UK is boosters.
Current @COVIDSciOntario data for Ontario are starting to show a turn around in vaccine protection against any infection.
This may be a booster effect, but could also be prioritized testing in symptomatic, high risk grps.
Reducing % of total pop infected can have big impacts.
Protection of vaccines vs hospitalization continues to fall (although fall is finally slowing).
Vax protection vs ICU admission is also falling, though more slowly. It's about 1 wk behind hospitalization. Hopefully it will hit lowest point in 1-2 wks then stabilize/turn.
Everyone 40+ get your booster as soon as you're eligible.
And if you're younger, have found a booster and know someone 40+ who needs it, give them the slot.
Urgently prioritize helping anyone 50+ get their booster. It will almost certain save lives.
Finally, with current improvements in vaccine protection vs any infection reported by @COVIDSciOntario estimated future deaths, ICU admissions, hospitalizations have fallen somewhat.
@COVIDSciOntario When "correcting" final numbers for previous severe outcomes, I'm also now assuming that 50% of these outcomes were not reported/not identified in Canada outside Quebec, so some of numbers for those regions have come down a bit.
@COVIDSciOntario Current estimates, adjusted to today's vax efficacy vs hospitalizations, ICU admissions reported by @COVIDSciOntario. Note, I assume vax still provides 90% protection vs death.
The ICU admissions and deaths reported today correspond to cases contracted at the time points indicated in red on this case curve.
Hospitalizations:
Total people in people with COVID-19 has just passed Wave 1 peak
New hospital admissions/day blew past Wave 1 peak a few days ago.
ICU admissions:
Total people in ICU just about to pass Wave 2 peak. Remember, ICU is about 1 week behind hospitalizations, so where hospitalization are now is where ICU will be in 1 week.
Media, you won't be able to attend this meeting (strategy), but if we decide to do press conference tomorrow morning we'll post info about it on Twitter this evening after the meeting.
Members of general public, we need to keep the group a manageable size (I'm really sorry).
Elected and non-elected officials welcome to participate. Our focus is not on attributing blame, but on very quickly developing a plan and communication strategy to advocate for action. This is a CONSTRUCTIVE meeting.
🔵9% Cdn pop infected Nov 15-Jan 4
🔵Omicron fatality, ICU admit rates 50% Delta, hosp rates 70% Delta
🔵2, 3, 4 week lag: hosp, ICU, death
We'd expect 420 deaths, 540 ICU admission, 6,100 hosp's for this period.
Reported: 1,063 deaths, 1,679 ICU, 6,999 hosp
This is based on Cdn pop age structure, age-specific vax rates, IFRs.
If Omicron causes 50% less deaths than Delta the expected national mortality rate is 0.1848, assuming there has been NO Omicron reduction in the 90% protection vs death provided by vaccines.
If Omicron causes 50% fewer ICU admissions than Delta the expected national ICU admission rate is 0.1540, based on current vaccine efficacy vs ICU admission for Omicron reported by @COVIDSciOntario
