Alberta: COVID-19 spreads exponentially

Daily new cases doubling time is ~ 3 weeks
We are already at a *1,000* daily

At this rate we will have:

Dec 08, 2200+ daily new cases
Dec 28, 4400+ daily new cases
Jan 17, 8800+ daily new cases

"The Nightmare for Christmas"

1/
Cases beget hospitalizations and deaths.

Hospitalizations doubling time is ~2.5 weeks

2/
ICU hospitalizations doubling time is < 2 weeks.

We will likely reach 100% capacity in less than a week.

3/
The question is not *if* people will die. They already do. The question is how many more avoidable and unnecessary deaths we allow to happen?

4/
We need serious measures *now*.

Half-measures don't work. Europe already did this experiment for us. There is no need to experiment on ourselves, when we know the results.
No need to replicate what didn't work.

Example of Czech Republic:

5/
The *proven* cocktail of measures that worked (turned exp. growth into exp. decay) in the West:

- quarantine of all incoming travellers / travel rstrxns
- shut down (w/ school closures!) *with financial support for businesses and people*
- support for vulnerable groups
- TTI
6/
Extra ingredient: Acknowledging COVID airborne transmission #COVIDisAirborne
- this helped Victoria, Australia to quench the last COVID transmissions.

7/
Super Bonus/ Major Price:

Those who kept above measures in place long enough (6 - 15 weeks, depending on where they started at, and how stringent the measures were), successfully got to #COVIDzero and now they have their normalcy back.

(NZ, Australia, Atl Canada & others)

8/
We can do it in Alberta. We have all the tools and the recipe. It's not too late to start.

Alberta: Exponential growth
Daily new cases doubling time is still ~2.5 weeks

Projection stays the same:
Nov 11, 1000+ daily new cases
Nov 28, 2000+ daily new cases
Dec 15, 4000+ daily new cases

We urgently need a decisive action to avoid a crisis.

1/ Image
We, together with most Western countries, achieved now the surge predicted by theory (red line) 👇

It's not too late to change the strategy

Let's follow NZ, Vietnam, Atlantic Canada, Australian states, and others, who succeeded in elimination
(elimination = no sustained community transmission)

(While our experimenting with "simmering" ended up with roaring flames)

AB doubling time is 2.5 weeks.
It seems to be über-exponential➡️the doubling time shortens with time.

At this rate we will have:
Nov 11, 1000+ daily new cases
Nov 28, 2000+ daily new cases
Dec 15, 4000+ daily new cases
and so on.

Cases beget hospitalizations and deaths.

It's too late for soft measures.
We need strong decisive measures + $$ support for businesses and people ASAP, in order to substantially *reduce the scale* of the upcoming disaster.

It takes 3-4 weeks from the shutdown date till the peak in cases and hospitalizations.

2/
If we shut down today, we will still reach at least 1600-2000 daily new cases, before numbers start to decrease.

If we shut down on Nov 15, we will reach 3000+ daily new cases before numbers start to decrease.

Either we control the virus, or the virus controls us.

AB: Daily new cases grow exponentially since May 25.

Doubling time calculated for May 25 - Oct 15 is:
50 days (~7 weeks) (95% CI [45, 57])

It can flip to a faster rate at *any time*
It cannot slow down by itself.

Even at a current rate it's bad;
It means:
....
1/
It means, that even if the growth won't speed up, we will have:
500 daily new cases by Dec 03
1000 daily new cases by Jan 21

and so on..., doubling every 7 weeks.

2/
Persistent exponential growth means that the virus spread is not under control.

It's not a "Slow Burn"* or a "Dance", oscillating around some fixed number.
This is a constant growth.
Slowish, yet persistent.

(*Disclaimer: I'm against Slow Burn as a goal. I'm for #ZeroCovid)
