Alright Minnesota. Make sure you don’t have a mouth full of water right now, because today’s #COVID19 report is eye-popping.

Ready?

By report date, Minnesota just set a new record high 7-day average case count.
Now, SOME of these new cases are backlogged. Some 8,000 of today’s record of nearly 30K new cases are more than a week old. (And remember this is a report covering multiple days.)

But even if you subtract those backlogged data, you’ve still got a record of more than 20K cases.
It’s hard to tell exactly whats happening, but this isn’t just an artifact of reporting issues.

Most of the data’s in now from Jan. 3 tests, and we’ve set a new record for most cases from a single day of testing — more than 11,000.
Our positivity rate by sample date data is still unsteady, with data from the past week trickling in, but we’re at or near a record high for the entire pandemic.
OK, so maybe you don’t think case counts matter much. Let’s look at hospitalizations, then. This metric lags case counts, but we are seeing non-ICU admissions rise steeply.
Don’t take this chart of cases by geography literally, because it’s by report date and is skewed by backlogged data.

But with those caveats, this suggests this case spike isn’t only in the Twin Cities metro any more like we saw last week.
This is pretty much what we should expect to see happening, since cases are spiking across the entire Midwest.
MN’s #COVID19 hospitalization levels only came down a little bit from our delta peak last month, so even if this omicron surge only leasts to small increases in hospitalizations, that could be enough to set records.
The #takes are coming fast and furious in my replies today.

Sadly for some of you, Twitter’s algorithm is judging a lot of them to be “low quality” and automatically filtering them out.
In many cases I only notice a filtered reply because someone whose tweets AREN’T filtered out gets into an argument with the first person; I see the replies but not what they’re replying to.
As of right now, Minnesota’s top five days for cases by sample date are:

Jan. 4, 2022
Dec. 28, 2021
Dec. 30, 2021
Dec. 29, 2021
Jan. 3, 2022

All within a one-week period.

And data is still coming in for Jan. 4 onward.

Before this, all our records were from November 2020.
(To clarify: Jan. 3 is the record high. Dec. 29 is #2, and so on.)

Minnesota’s #COVID19 data is still messy and backlogged, and hard to interpret. Today’s 10K newly reported cases would be the most ever reported on a Monday — but a lot of these cases are older than usual due to a backlog.
More than 5,500 of today’s 10K cases were from tests conducted a week ago or older.

So far the most recent days for which we have non-negligible case counts (last Wednesday & Thursday) have relatively low positivity rates. But this might just reflect a lag in processing cases.
So if you include the incomplete data from Wednesday & Thursday in the data, it looks like Minnesota’s positivity rate has peaked and is dropping.

But it’s WAY too early to conclude that with lots of cases not yet reported.

Found this amazing c. 1852 piece of dataviz: a propaganda medallion featuring Napoleon III’s electoral margins in every French department in the referendum on whether to re-establish the French empire. (He “won” with 96.9% support.)
The back is also fascinating, featuring Bonapartist slogans:

The voice of the people is the voice of God
The voice of God is universal suffrage
Universal suffrage is true legitimacy
True legitimacy is stability
Stability is heredity
Heredity is peace
Peace is progress
...

Progress is work
Work is happiness for all
Happiness for all is improving everyone’s lot

“Improving everyone’s lot is the most sincere and ardent wish of Louis-Napoléon. Long live the Emperor! Forever and ever.”

MN’s #COVID19 data continues to be very messy — nearly 5,000 backlogged cases from last week in today’s report, and more likely to come in the next few reports.
As a result it’s hard to tell exactly what’s going on. Some measures are up, some down.

SO FAR the last few days we’re not seeing the giant *increases* in cases/positivity we saw starting around Christmas. But it’s too early to celebrate.
As of the equivalent report last week (released on Monday instead of Friday due to the holidays), we had reported about 6,100 cases from Monday (12/27) on 44K tests.

As of now, we’re at 4,400 cases from Monday (1/3) on 67K tests.

But slow case processing could explain this.

Unfortunately, today’s #COVID19 data in MN has yet another backlog situation.

A few days ago the share of MN’s total tests that were antigens spiked upward. Turns out that’s because a bunch of PCR tests weren’t making their way into reports. (People still got notified.)
Even more unfortunately, @mnhealth is going to be updating their TEST totals today — 135,000 backlogged tests from the past week or so — but CASES from this backlog will get updated over the next few days.

So all our messy data just got even more messed up. Buckle up.
The end result: MN’s positivity rate is going to look artificially low today, and this will linger into next week until all these backlogged cases are finally processed. So don’t let this mislead you about how things are going in MN.

Today’s #COVID19 report in Minnesota showed a week-over-week drop in raw cases.

But if you’re not yet adjusting for testing volume, here in the year 2022, you may be beyond my help. The news is still bad; our average positivity rate shot up again, to 15%.
Today’s data are a little weird. We’ve got a big chunk of cases from last Thursday, before NYE, & then a big chunk of cases from the holiday weekend, when few people got tested but a lot of the ones who did were positive.

Again, never read too much into any one day’s report.
Newly reported cases fell overall today, due to lower testing volume, and @mnhealth only releases test totals/positivity rate by county on Thursdays for some reason, but w/ that, overall we’ve still got new cases in Hennepin/Ramsey higher than they’ve ever been all pandemic.

Today’s #COVID19 report in MN reflects 4 days of data, important context for the record 16K cases reported.

BUT STILL: Today’s report is eye-popping. The omicron spike is *here*. And this is just one part of the state, the Twin Cities metro, being hit. Greater MN still flat-ish
This surge in cases is being led by 20-something adults, but we’re seeing spikes in every age group except seniors.
Hospitalizations lag behind case counts a bit, but there are some suggstions that MN’s decline in #COVID19 bed use may have leveled off.
