Twitter seems to be responding to @CDCDirector comments stating that Covid-19 deaths in the United States are rising. I didn't hear the briefing, but I will comment on the contention that Covid-19 deaths are rising:
That contention is wrong. Deaths are not rising.
Thread🧵
It's first important to distinguish between date of death and date of reported death. The latter (inevitably) follows the former, but by how long? It depends. Sometimes a few days. Sometimes weeks. Sometimes months. Sometimes several months!
We have the normal reporting flow (days or weeks).
We have backlogs created in times of stress that take time to resolve (weeks to months).
We also have audits, death certificate matching, or just plain missed deaths (L.A. & Ohio recently) (potentially several months).
At any given time, any or all of these could be going on in different states, and to varying degrees.
Texas's deep freeze two weeks ago strangled reporting of many metrics, leading to small numbers, followed by larger numbers last week once the weather abated.
Virginia, on the other hand, is on Day 10 of death certificate processing for deaths that occurred during the post-holiday surge two months ago. They've "reported" more deaths in the last 10 days than they did in the previous 38 days! But these aren't "pipeline" (recent) deaths.
Solely removing these two states from the numbers (which I report nightly), we have the following 7-day averages for deaths:
15-21 Feb: 1740
22-28 Feb: 1494
We declined 14.1% week-over-week as of yesterday's data without those two (wonky reporting) states.
Again, these are reported numbers. Other states have cleared backlogs lately as well. This happens every time we have a major spike: things eventually subside, the states catch up.
What this means is that the spike was actually worse than the time when it was reported.
Given the fact that hospitalizations and ICU numbers have been on a consistent decline for nearly 7 weeks straight now, and % testing positive has declined week-over-week for 50 days in a row, it strains credulity to think that "actual, current" deaths are anything but lower.
However, excepting reporting artifacts, even *reported deaths* are declining.
(In fact, even with TX and VA included, yesterday was our lowest 7-day average since the first week of December)
To recap:
- No evidence current deaths are increasing
- Reported deaths also not increasing
- Cases have increased slightly, but tests have increased even more (% positive decreasing)
- Hospitalizations/ICUs decreasing consistently.
- Vaccines = increasing.
Tis good news!
PS: I'm no zealot, and I'm pragmatic enough to understand the political desire to "nudge" people toward safety. But I will forever maintain that it has the opposite effect. Absolute transparency with pleas for caution during this final stretch would be a better tact.
PPS: Imagine a politician saying this: "Trends are positive, and I'm asking for your help over these crucial next 60-90 days to put a lid on this thing once and for all. Let's look out for one another and stay safe as we transition back into pre-Covid life, . . . (1/2)
"which is coming soon. I can't tell you how much I'm looking forward to this summer. To family. To friends. To barbecues and hugs. The numbers are leading us to this outcome. Let's work together to keep it that way."
Seems better, no? (Even for the most skeptical citizens)

Virginia just posted another large chunk of Covid-19 deaths today, mostly backlog. VA's piecemeal backlog reporting is skewing the US's recent trends. Look at this:
Of course, as it states on its website, most of the recent reported deaths are matching death certificates from the holiday and post-holiday period (more than a month ago)
On the left, VA deaths by date of death. On the right VA deaths by report date:
Despite this, many headlines—and even the updates contained within—make no mention of pairing older deaths. Like this one: wric.com/health/coronav…
Where does the US stand on #Covid19? Not a simple question. I tweet Covid data daily, and the trends have been positive for weeks. But I often get asked, “when is this over?” What about #b117? And seasonality? And the vaccines—shouldn’t they change the trajectory?

Full disclosure: I’m a realist guided by data but with a bias toward optimism. I also don’t give one tiny, insignificant shit about the political ramifications.
The overall takeaway is that we’re looking a hell of a lot better today than in November, December, and early January.
Covid deaths, by and large, will define the pandemic, so it’s easy to rely solely on that metric as a barometer for current success. But it’s a poor real-time bellwether. By now, everyone assessing the data (in good faith) should be aware that reported deaths lag other metrics.

@COVID19Tracking Today is the first day of the pandemic that the United States hit 4,000 reported deaths. It pushed our 7-day-average back to a new peak of 2,774.
The holiday reporting lull has left the building.
@COVID19Tracking Our 7-day-average for those currently in the ICU has now increased week-over-week for 100 days straight. Hospitalizations are at 102 days straight.
Both metrics have also been increasing at a higher percentage in a couple weeks since Christmas. Not a ton higher, but higher.

@COVID19Tracking Raw hospitalizations (non-7-day-averaged) have dropped for 3 days straight. That's the first time that's happened since October 2-4.
@COVID19Tracking California's share of hospitalizations and ICU numbers continues to climb. California comprises over half the hospitalization increase in the country and over 3/4 of the ICU increase.
It feels like we could see other-than-California peak within a week in both numbers.

@COVID19Tracking Reported average daily deaths seem to finally be showing the results of our high case counts (+ high % testing positive).
If the past is any guide, it runs at a ~21-day lag. We were in the mid-80k range 21 days ago. We're double that now. Not a great harbinger for mid-December.
@COVID19Tracking Happy to see a decent-sized drop in % testing positive today. I'll be happier still when we see smaller absolute percentages nationwide.
It is getting tiresome watching media, government, and other Twitter folks present erroneous numbers for certain states’ #Covid19 positive testing percentage.
Many of the Johns Hopkins percentages are flat wrong, and it's the denominator problem (again).

First, it’s important to know that these aren’t "Johns Hopkins' numbers." Their testing data is from @COVID19Tracking, who gets it from state websites.
But there are 3 options from which to choose the test number. Here are the definitions of each, in CTP’s priority order:
