Memphis/Shelby County
Covid Week-In-Review

tl;dr
* 538 cases/day this wk (record high)
* cases +102% over 6wks, +244% over 8wks
* tests +41%, +82%
* this was the worst wk yet
* last wk was 2nd worst
* next wk will be even worse
* but you can save lives

1/
Here are avg daily cases per wk, for every wk of the local pandemic since we reopened in May.

The past 5wks represent the #1, #2, #4, #5, & #6 highest wks yet.

Not only are we in the worst of it, but we've been in the worst of it for a month now.

And it's getting worse.

2/
But the past month is even worse than we knew.

We started experiencing significant reporting delays beginning Nov1.

Since then, avg daily cases reported have been 53 cases (13%) below actual cases once the testing gets processed and assigned to the date of the test.

3/
Here are avg daily cases by test date. The one of the left was pulled today. The one of the right was from Wed (Dec9).

On Wed, Nov30 was at 657 cases.
Today, Nov30 is all the way up to 700 cases.

That wk, 465 cases per day were reported.
Actual cases avg'd over 500 per day.

4/
Dec4 is the most recent day here. But bc of reporting delays, Nov30-Dec4 are not accurate. Cases are still being added.

That said, the 10 highest days on record are:
Nov30, 700
Nov23, 650
Dec1, 626
Nov16, 620
Dec2, 596
Nov9, 579
Nov24, 547
July15, 535
Nov13, 526
Nov10, 525

5/
Here are cases per day by report day, all the way up to the record-high 930 reported today.

The 7-day avg is up to 538 cases per day.

But reported cases have been off by 13% for the past month, so it is likely that we are actually already avg'ing over 600 cases per day.

6/
Here are my projections for the next 3wks.

You'll notice that I changed my growth rates from 0.8%, 0.9%, & 1.0% to 0.9%, 1.0%, & 1.1%. That's bc the growth rate is increasing. We avg'd 1.0% this wk.

It's looking like we could hit 700 cases/day by Jan1.

7/
We reached 50k cases a wk ago, Dec5.
That took 272 days.
It will take less than 70 days for the next 50k.

The first 10k cases took over 100 days.
20k, 28 days
30k, 52 days
40k, 52 days
50k, 25 days

60k will come on Dec23, 18 days.
70k, 15 days.
80k, 14.
90k, 11.
100k, 11.

8/
Here are covid deaths. You can see a clear trend up from mid-Oct to now.

And we'll likely see the death rate start to increase as our healthcare system becomes more and more strained.

We're avg'ing 5 deaths per day. I hope I'm wrong, but I project 20 deaths/day by Jan14.

9/
Once our healthcare system reaches capacity, which looks like might happen within the next month, deaths will skyrocket.

10/
Hospitals are already at capacity or near capacity.

The real problem locally is staffing. The governor has deployed National Guard medics to help.

wreg.com/news/coronavir…

11/
And healthcare workers are the largest group to test positive for covid. (Second is manufacturing & warehouse workers, third is school employees.)

This is a real problem. If nurses are sick with covid, that strains our already-thin staffing.

12/
But it doesn't have to be like this.

We have successfully flattened the curve twice now, once from March into April, then again from Aug through Sept.

If we did it before, we can do it again.

The only thing stopping us is the will to do so.

Let's flatten the curve.

13/
In fact, we could go even further than flattening the curve. We could just get rid of covid altogether.

It's possible.

Look at Melbourne, Australia.

The city is the size of DC, 5x larger than Memphis, but has not had a new covid case in 4wks.

vox.com/2020/12/4/2215…

14/
Now is not the time to give up.

With vaccines on the way, we can see the finish line.

Now is the time to set a new goal and to rally the community together.

15/
We can literally save thousands of lives.

Have you ever have the chance to save thousands of lives?

Probably not. And you probably never will again.

This is a once in a lifetime opportunity.

16/
So what can you do?

1) Stay home.
2) Or outdoors.
3) Keep your distance.
4) Wear a mask.
5) Buy local. Gifts, gift cards, takeout.
6) Donate to nonprofits.
7) Tell Congress to provide financial relief to state & local govt, small biz, & individuals.

17/
But we need a goal.

And I think we have to make schools our priority.

The district announced yesterday that, bc of the surge of covid cases, it will delay reopening in-person.

Let's rally around our children.

tn.chalkbeat.org/2020/12/11/221…

18/
Here's our goal:

Given that schools have been closed since Mar13, 2020, Shelby County will have fewer than 10 daily cases per 100k ppl & a test positivity rate under 5%, for 14 consecutive days, by Mar22, 2021, so that schools can reopen safely.

dailymemphian.com/article/15774/…

19/
We know what the end of the story looks like. Vaccines are on the way to save us. But there is plenty of story yet to be written.

The question is, what does the next 3-6 months look like?

The choice is ours.

Let's choose life. And let's invest in our future.

20/20

Mid-Wk Covid Report

tl;dr
* it's bad, y'all, and getting worse
* but they say it's darkest before the sun rises
* and we have a once in a lifetime opportunity to save literally thousands of lives, just here in Memphis
* read for details

1/ Image
Let's start w/new cases by test date. There's a built-in lag here, so it only goes through Nov30.

But as you can see, the 4 days with the highest number of new cases were the past 4 Mondays, at 577, 610, 651, & 657. (And bc of reporting delays, that number is still rising.)

2/ Image
Here are cases by report date.

We've avg'd over 435 cases/day for 8 days now. That's the 1st, 2nd, 3rd, 4th, 5th, 6th, 9th, & 10th highest avg's on record. All in Dec.

The 7th, 8th, 11th, 13th, 14th, & 15th highest were all in Nov.

The 12th was in Aug, the 15th in July.

Let's zoom out and look at the shape of the local pandemic since the beginning.

Note that this graph of cases by test date only goes through Nov24.

So we were in the worst of it...before Thanksgiving.

2/
And since November just ended, let's zoom out to look at the local pandemic by month.

[Note: New metrics were introduced mid-Sept.]

Mid-Wk Covid Report

tl;dr
* cases +260% since sept30, testing only +52%
* positivity rate up from 5.2% to 10.7%
* hospitalizations at record-highs, staffing is a problem
* vaccines are on the way...if we can make it to spring

1/
We've had problems with the case data since Nov1.
Read here:

In the meantime, hospitalization numbers are the best we've got. And we've been setting records literally for wks now.

"Elective" surgeries are being canceled. Staffing is a problem.

2/
Here's the most up-to-date data we have on cases. This is a graph of daily cases by the date the test occurred.

A few things here...
1) The most recent data here is a wk old.
2) Bc of reporting delays, cases are still trickling in.
3) This is the worst we've seen.

November just ended, so here is the shape of the local (Memphis/Shelby County, TN) pandemic by month. Image
Two big things stand out to me.

First, cases grew tremendously from October to November, while testing was largely flat. That does not bode well for the weeks ahead. It likely means that we have missed a large number of cases.
2) Deaths kept rising after this summer's peak in cases. That says we can likely expect deaths to rise in Dec. Also, the Oct spike in deaths likely represents cases from the summer, which suggests that we could expect deaths to continue even after our current wave subsides.

Let's start with the national picture.

This is from @COVID19Tracking.

It's pretty bleak. Cases are growing exponentially, much faster than tests. Hospitalizations are at an all-time high. And we're avg'ing 1400 covid deaths each day.

2/
But @youyanggu estimates that the true number of cases is 3.3 times more than what's being reported.

FYI, Youyang had the most accurate covid model in existence. He's switched from forecasting to "nowcasting," estimating what *is* happening rather than predicting what will.
