Recommendations this week are still cautious, even for regions where the forecast is currently ELEVATED or HIGH.

Why? Because @INSPQ survey of RAT/PCR+ people for week of Feb 5 found 69% increase compared to week before. It's often the first indicator to go up at start of surges

@INSPQ Data for other indicators that go into our forecast, such as test positivity rates, waste water are roughly 2 weeks behind the forecast date.

We're not seeing forecast scores shoot up yet, although curves are slowing/bending back up for multiple regions.

So, caution advised.

Bloody Twitter. Keeps prompting me to save or discard tweets when I want to send them. It's possible there may be some service interruptions on this thread, folks.

You'll hear anguished cries from the direction of Ontario.

For those who often wonder why the COVID Forecast for QC goes up and down faster than for many regions (and doesn't get stuck at the highest points for as long).

Part of it is reporting--QC reporting is faster and more complete than most Canadian regions, and there's not as much of a problem with severe outcomes trickling in for weeks/months after they've happened.

But also, QC and the Prairie provinces too seem to have had a better go of Omicron than provinces that likely had experienced fewer severe outcomes and infections pre-Omicron.

The other thing that's important to know about the Prairie provinces and QC is that reporting of hospitalization and ICU admissions is pretty decent in all of these provinces. We don't see as much of the prolonged, dragged out reporting that we see in Atlantic Canada and Ontario.

BC hospital/ICU admission reporting is pretty decent too, at least compared to ON and Atlantic Canada. BC death reporting has really improved in the last year or so, but it's still a bit protracted, which may contribute to BC COVID forecast scores stalling at high points.

We also know from @COVIDimmunityTF seroprevalence data that as of early Dec, BC, ON and Atlantic provinces still had the lowest % the total population infected at least once.

So it's likely there's a bit more tinder (and more expected severe outcomes) in these provinces.

@COVIDimmunityTF After that tangent, back to the forecasts

@COVIDimmunityTF Aargh. Too much chat. Not enough attention to detail. Just made a mistake in my Ontario tweets.

Starting them over.
