I have drafted multiple rage-tweets following today's 2 pressers, but realize that I am just emotionally exhausted from the inevitability of it all:
- people getting sick
- families and businesses ruined
- healthcare overwhelmed

Let's start with what won't work:
2- TO 4-WEEK CIRCUIT-BREAKER:
These WILL reduce the case load. But, if we take the examples of Melbourne and Belgium, the halving time will be somewhere between 7-14 days, depending on completeness and adherence of any "circuit-breaker".
If we start at, say, 1300 cases, then we can expect getting to 650 cases in, say 7-14 days, 325 in 14-28 days, and 162 in 21-42 days. That would bring us to where we were around Labour Day. Taking our foot off the breaks, though, would expectedly bring us back up to where we are.
The longer we delay this—with 6% growth at present—the more prolonged the circuit-breaker.

COLOUR-CODED STAGES
I used to believe in this concept, until I realized that—regardless of the stringency—it requires a situational awareness (surveillance) we do not have at present.
It also will result in clearly prolonged restrictions, based on our current experiences in Toronto and Peel. This will expectedly harm businesses for the next 4-6 months but (and this is key) no reasonable assuredness of regaining any kind of clientele until warmer weather.
EPI-BASED TARGETING OF RESTRICTIONS
This is what @brianlilley and some others keep calling for—so-called "evidence-based restrictions". It is elegant (go to where the outbreaks are), but suffers from "squeezing the balloon" (a term from #antimicrobialstewardship):
Today's banquet hall, is tomorrow's private home; today's house of worship is tomorrow's enclosed tent; today's restaurant is tomorrow 4-walled patio; today's workplace outbreak is tomorrow's apartment outbreak.

Today's visible problem is tomorrow's (temporarily) invisible one.
Everyone wants a public- and business-friendly, painless solution, but there is none. Sadly, there is no painless solution

WHAT WILL WORK
a) go really hard on COVID-19 now, and do everything possible to protect vulnerable, and financially support businesses (calling @cafreeland)
b) buffer up testing capacity and contact tracing
c) focus on isolation and quarantining with HEAVY SUPPORT (for those who can't otherwise) AND FULL WEIGHT OF LAW (for those who won't otherwise)
d) pursue what we know to optimize masking, distancing, crowding, and ventilation
I know political decisions are being made, but I am trying to separate these out as much as possible. I also believe that the Premier and his govt are doing what they feel is right. It isn't.

There is no "balanced" approach to this that averts the misery ahead.
Deep down I know that nothing will happen until the front page of the newspaper shows an overwhelmed hospital, or patients getting O2 outside the hospital, or a triage "tent" gets built, or a healthcare worker crying.

But maybe, just maybe...

What is wrong with Ontario's latest approach to COVID?

It is #So1stWave. Emerging from the first wave, we were happy we survived it, and thought that if we could just keep case counts reasonably low or prevent hospitals or ICUs from being overwhelmed, we would win the battle.
This is the ExCUSE (Examples of Canada, US, and Europe) approach. The govt. released their new plan predicated on this thinking. If I were to bet, it was conceived over 6 weeks ago (i.e. around Sept. 23). To remind you, this was ExCUSE total deaths and cases 6 weeks ago.
I will focus on 2 countries to demonstrate what happens when you take a #So1stWave approach. We will start with Belgium (pop 11.5m), using data from @OurWorldInData and Belgium's National Science Institute: epistat.wiv-isp.be/covid/covid-19…. Here was where they were Sep 23. <4 deaths/d.

Prompted by several posts and threads, I am going to outline what I view as the "A-PAC Approach"

A-PAC refers to Asia-Pacfic and Atlantic Canada: 🇦🇺(25M), 🇨🇳(1.39B), 🇯🇵(126M), 🇳🇿 (5M), 🇰🇷(52M), 🇹🇼(24M), 🇹🇭(69M), and 🇻🇳(96M). Atlantic 🇨🇦 has 4 provinces ((NS, NB, NFLD, PEI, 2.4M)
These countries/provinces have varying geography, population size and density, degrees of democratic norms; some are islands, but others share sizable borders. Several have used a cordon sanitaire (i.e. making a region an island, even if it isn't one) to create an "island".
The A-PAC Approach consists of 6 principles:
1. Aim for really low number of new cases and zero transmission
2. Ensure any new people (esp. cases) coming in from outside are quarantined
3. Aggressive test-trace-isolate
4. Strong public health leadership

I have spent the past day weighing whether to like article because it is a fantastically executed example of #scicomm or dislike it because it is propaganda that distorts the evidence.
english.elpais.com/society/2020-1… via @elpaisinenglish
What makes it so effective is the #dataviz, the relatable examples, and the plainspeak. I read the translated English version, and it really is wonderful to read. I came away thinking that aerosol transmission was so clear and plainly obvious. Until I realized this is propaganda.
It quotes a letter as an "article in the prestigious @ScienceMagazine" [finding] that there is 'overwhelming evidence' that airborne transmission 'is a major route'" for transmission. This is misleading.

As @JPSoucy points out in this excellent 🧵, we have a experienced a considerable drop in testing. The question we don't know is: how many should we be testing? @skepticalIDdoc and other super-smart people suggest keeping our eye on %+. I am going to try to reframe the problem.
I will start off by saying this:
"cases" are numerator
"tests performed" are denominator
"% positivity" are cases/tests performed

If you do 20 surveillance tests (i.e. in asymptomatics) in a school, or 200, the % positivity will remain the same, but the "cases" will increase.
Cases matter.
They theoretically matter to the case (so they can receive treatment if they need it).
They should matter to public health to identify contacts (who may be infected) #ContactTracing
They should matter to everyone if we are treating them as surveillance.

This is a followup to my thread yesterday to help the public understand better what is going on in Toronto (and Ottawa, Peel, and the rest of Ontario). I am going to focus on what everyone needs to understand about the ON testing fiasco (which is being played out elsewhere too)
First: I get my data from @jkwan_md @imgrund @JPSoucy @ishaberry2 to support my understanding. They get it primarily from publicly available sources, and make the data easy to understand.

Second: our daily case # in ON are artificially low (by ~330) because of the backlog.
The backlog was entirely preventable. I was told months ago when I asked that the reason labs weren't able to increase capacity was $$ from govt. @bruce_arthur covers this accurately here

My biggest concern in Toronto at present: the public doesn't understand the acuity of the situation, and are therefore understandably upset at current developments. So I will try and outline my understanding of the current situation:
Testing: we have a 7-day average of about 240 cases/day. This is an underestimate of the number of tests, because of a) backlog, b) system challenges that are dissuading people from being tested, c) over-weighing of younger cases, which makes asymptomatic cases more likely.
Regardless, our testing system is overwhelmed, and so we have no gauge on our gas tank.
The number of cases has totally exhausted @TOPublicHealth capacity. . So not only no gas gauge, but we also don't have a map for where we are going.
