Here are projections I made in May/June

Note: AH has access to data, computers, and internet even more than me. I have 1 brain. They have many brains to work on models and monitor global situation

We could have A (no COVID→normalcy back)
But GOA and AH chose B for all of us
1/
Please note how close the reality is to the centre trajectory projected 8 weeks ago, when overall cases were still going down
The spread of SARS-CoV-2 is HIGHLY predictable.
(If someone tells you otherwise, that only means that it is beyond their personal analytical abilities)
2/
Others have been saying the same thing as me. Below are models by Prof. Colijn. From *May 31* (!).

GOA and AH and some advisors must have seen them (that’s their job), but they did this: 🙈🙉 lalalala!, while implying that “the pandemic is over”.

theglobeandmail.com/canada/article…

3/
GOA and AH lifted mask mandates & allowed large gatherings. That ensured that vaccines, in-person school break & warm weather won’t have a chance to stop the spread “by accident”. And they didn’t.
Spread must go on.🎶

Since 14 months we are being forced to live with COVID.

4/
For how many years more?

5/
A reminder:
“Living with COVID” is a decision, not a biological inevitability.
W/ elimination strategy, a region can stop community transmission in just 5-10 weeks, and get back to a relative normalcy, which is sustainable

AB daily cases are doubling every 14 days.

At this rate AB can reach:
2000 daily cases on Sept 11
4000 daily cases on Sept 25

ICUs may be full around Sept 11 [Sept 01-Sept 27] (see next tweet)

GoA can act now and prevent deaths and suffering or again wait till ICUs are full. Image
'ICUs/daily cases' ratio is *not lower* than in 3rd wave. 7 day average stays above 7%.

In the 3rd wave ICUs were more than full (in debt mode - postponed elective surgeries and such) at 2000 daily new cases.

Hence we can expect ICUs full @ 2000 daily new cases or earlier.

2/ Image
Reopening in-person schools at the time when ICUs are about to be full is not safe.

AB has just 47 paediatric ICU beds.

We should now use all the tools we have to stop this spread. And then reopen safely.

AB is in the #DeltaWave
Daily cases doubling time: 9.8 days

At this rate we can expect:
5000 daily new cases on Sept 14
8000 daily new cases on Sept 21
(pls see confidence intervals on the graphs)

5-8K daily cases is when we might expect ICUs full
...
1/
The link between cases and severe illness is not broken.
The ratio is different. But the correlation stays.

2/
In UK, hosp:cases ratio is now reportedly 4x lower.
In Israel this ratio is now 2.5-3x lower than in the 3rd wave.

In AB our ICUs were full at 2000 daily cases.
2000 x 2.5 = 5000
2000 x 4 = 8000

Hence, we could expect to have ICUs full at around 5000-8000 daily cases.

We can’t vaccinate our way out of the pandemic.
We need both: Vaccines AND Public Health (PH) measures.

It was barely possible w/ original variant (A). W/ Delta, both PH measures and vaccines became less effective (B). But combined – they may still work.

Theoretical model:

1/ ImageImage
Even if vaccines are only 60% efficient against transmission & only 75% eligible people (64% total) get vaccinated, by combining PH measures & vaxx we may still be able to control the spread (C). Barely.

But…

2/ ImageImage
But if by allowing the reckless spread we culture a variant 2x more transmissible than Delta → our current strategy (i.e. acting only when ICUs get full) won’t work anymore.
Our tools: PH measures & vaccines will not be effective enough to quickly halt the exp. growth (D)

"better data along does not guarantee better outcomes"

Especially when results coming from such data are actively dismissed and purposefully obfuscated.

On Feb 12 AB had enough data to be *certain* that w/o extra measures it will produce the 3rd wave.

On Feb 12 AB had enough data to be *certain* that w/o extra measures it'll produce the 3rd wave.
It was *clear*.

Thank you everyone who contributed to the 3rd wave by saying things like: "models are wrong".
Even w/ limited data, but knowing the properties of the phenomenon, models predict the future darn well.

On Feb 01 I knew, that if we won't implement measures, there'll be a 3rd wave.

On Mar 17 I could bet my soul, left kidney, and a collection of stuffies on that.

Alberta: Current measures made the growth rate less extreme.
B117 is doubling now every 20 days instead of every 7 days.
It's still very fast - similar to doubling time in the 2nd wave (18 days)

Current measures are insufficient to bend the curve downwards.

Ln scale graph 👇
At this rate we can expect:

3,000 daily new cases on May 12
4,000 daily new cases on May 22

2/
This wave is worse than the fall one.

2nd wave: at 1877 daily cases we had 100 ICUs
3rd wave: at 1860 daily cases we have 146 ICUs, and *we are still growing*

That's *despite* many people being already vaccinated. W/o vaccines it would be even worse.

Alberta could see the same number of new COVID-19 cases by mid-April as there were at the height of the second wave in December.

~2000 by April 19,
~4000 by April 29

Thank you @laurby for interviewing me for this article.

Projection from 2 days ago. Turns out conservative.

Today's actual total cases: 717 (projected: 563)
Most recent B117 doubling time: 7.3 days (faster then on this graph)

2/
W/ update: calculated today, the B117 doubling time is 7.3
R value: 1.46
