Earlier this week, a judge overturned the transportation mask mandate, which I covered here. I will also be covering the situation in China in its own post.
No one asked this time around, but a friend recommends this P100 mask if you’re looking to go big rather than go home.
The biggest other news is that Omicron continues to cycle into new variants.
There’s BA.2.1.12, there’s BA.4 and there’s BA.5.
All seem to be more infectious than BA.2.
Which was more infectious than BA.1.
Which was much more infectious than Delta.
Which was more infectious than Alpha.
Which was more infectious than the original strain.
We’ve come a long way. China is still attempting Zero Covid, which I will cover in the China post, but that is looking more and more like state failure to adapt to reality than a reasonable policy choice. Covid-19 is here to stay, at least until we can get a nasal vaccine that prevents transmission, research towards which is not currently something we are even willing to properly fund.
Executive Summary
Moderna booster candidate looks great.
Cases and deaths radically down on paper due to Easter, mostly ignore.
Things increasingly returning to normal, travel mask mandates lifting.
China situation is scary, will be covering that in its own posts.
Let’s run the numbers.
The Numbers
Predictions
Prediction from last week: 250,000 cases (+13%) and 3,900 deaths (-10%).
Results: 231,576 cases (+4%) and 2,402 deaths (-45%!).
Prediction for next week: 277,800 cases (+20%) and 4,100 deaths (+71%!?)
Easter (and perhaps Passover) suppressed cases and somehow even after two years I seem to not properly adjust for such things – but even then, I mean, that death number, come on. When I break things up into regions it seems likely that last week wasn’t getting ahead of itself, and we should expect some ‘catch up’ growth in cases this coming week.
The death count is clearly artificially low, at least in terms of comparing it to expected future calculations, especially in the South. I am anticipating many of those missing deaths being counted in the coming week. There is however also the possibility that this also partly represents the drop-off of ‘legacy’ deaths that are only sort-of Covid deaths, as it is still above 1% of cases reported a few weeks ago whereas the real IFR is going to be a lot lower than that. So it’s not like the number is fully impossible.
I will note that there has been no mention of the decline in deaths among all the people talking about the transportation mask mandate being lifted. Now more than ever, this is not about death.
Deaths
A number of states reported zero deaths. A lot of others had epic drops of more than half.
Cases and deaths in the UK have diverged, which many say is due to the decline in testing.
In such situations, the place to look is the positive test percentage.
This confirms that the undercount got larger during March before peaking, and there was likely a similar undercount to what we saw in the January peak. Yet the number of cases recorded was far lower while the number of deaths was briefly higher. I do not think the death count was ever actually higher than it was in January, but despite that this is still suggesting that the test percentage stat was underestimating the degree of undercounting.
Saying that case counts ‘no longer have value’ seems to me like going too far. It definitely has some value, and especially it has value in relative terms now that we have a baseline for the new policy regime in the UK. What we can’t do is directly compare free-test world to not-free-test world without making the right adjustments.
As always, if you wait long enough, deaths tell the story. The story they are telling is that things in the UK are roughly...
