Welcome to The Nonlinear Library, where we use Text-to-Speech software to convert the best writing from the Rationalist and EA communities into audio. This is: Covid 1/20/22: Peak Omicron, published by Zvi on January 20, 2022 on LessWrong.
The Omicron and Weekly posts are now combined, so this includes the last day’s Omicron developments, which will be how it works going forward. Next week’s will include the probability updates section as well. When there is urgent news, I’ll supplement as appropriate.
This week was the peak. From here, it would be highly surprising if Omicron cases didn’t start declining. The other news is mostly more of the same, with several developments worth analyzing: The Supreme Court throws out one of Biden’s mandates but upholds the other, Djokovic gets deported a second time, a great proposal to expand Manhattan (which got its own post), and other neat stuff like that.
Executive Summary
If you live in USA and haven’t done so yet, order your free Covid-19 tests.
We are at or past the peak in Omicron infections in the United States and UK, but that doesn’t mean it’s over yet, next few weeks still rough.
UK lifts all Covid-19 restrictions, midnight is perhaps temporary after all.
Let’s run the numbers.
The Numbers
Predictions
Prediction from last week: 5.6mm cases (+13%) and 15,000 deaths (+30%).
Results: 4.9mm cases (+0%) and 12,606 deaths (+7%).
Prediction for next week: 4.4mm cases (-10%) and 14,500 deaths (+15%).
The deaths number is confusingly low this week. Cases increased by a huge amount with the three week lag, yet the deaths number isn’t increasing much. There’s about to be a much bigger three-week-lagged increase in cases, but the pattern is clear so my estimated size increase needs to adjust. I am fully prepared to miss low reasonably often here, if I wasn’t the estimate would be wrong.
For cases, it seems clear that we are peaking, so we should expect things to begin to decline. The question is how fast, with some areas not yet peaked, and the Northeast already having a much smaller share of total cases. The decline could easily be much faster than this, but things could also stay mostly steady for one more week.
Deaths
Even with Omicron being milder, the lack of more deaths is very good news here. The next week is the time when deaths should by all rights go much higher, so if they stay under control this week, we’re fully in the clear.
Cases
The Northeast already peaked, as probably did a number of other large states like Illinois, Florida and California. The South might have one more week left in aggregate, it also might not.
Cases at Yale in similar freefall to rest of east coast.
Thread pointing out that cases are declining in many places.
Trevor Bedford thread on us having peaked nationally but often not locally, including good state-by-state graphs. Expects about a symmetrical march down to the path up.
Ashish Jha thinks we have peaked.
Vaccinations
US announces (MR secondary source, StatNews article) that.
.if the Food and Drug Administration decides to update Covid-19 vaccines to take better aim at Omicron or other variants, it is unlikely to go it alone.
Instead, a senior FDA official told STAT, the agency expects to take part in an internationally coordinated program aimed at deciding if, when, and how to update Covid-19 vaccines. The approach would ensure decisions are not left solely to individual vaccine manufacturers.
“We can’t have our manufacturers going willy-nilly [saying], ‘Oh well, the EMA decided they wanted this composition, but FDA wanted that composition,’” the official said, referring to the European Medicines Agency. “So we are very much of the mind that we would like to be part of a more global process in helping to come to what vaccine composition there should be now.”
Tyler is kind:
Designed for flexbility and speedy response? I guess we’ll see. Here is the full StatNews article. And obviously, the entire public health community is up in arms about this.
