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: Long covid: probably worth avoiding—some considerations, published by KatjaGrace on January 16, 2022 on LessWrong.
I hear friends reasoning, “I’ll get covid eventually and long covid probably isn’t that bad; therefore it’s not worth much to avoid it now”. Here are some things informing my sense that that’s an error:
A. Really bad anecdotes aren’t hard to find.
I asked for people’s long-covid experiences on Twitter and got more than a hundred comments mostly full of truly awful stories, almost entirely from people I don’t know at all, presumably somehow brought via the active Long Covid community.
This is a bit hard to interpret as a datum, due to the intense selection effects involved, but my main inferences are:
The bad tail gets very bad.
This bad tail is less like a quantitative reduction in labor, and more like psychological torment, being very sleep deprived or brain damaged while dealing with a host of legitimately scary health problems (see below) than I had been picturing.
The very bad part of the bad tail is not tiny. Like, if I requested lightning strike experiences, I don’t think I would get this kind of response.
See this for more heavily selected but still scary anecdotes about what bad cases can look like.
B. Bad anecdotes are common enough to show up in my vicinity.
Among this cascade of terrible stories is a response from one of the handful of people from my extended network who I already knew had had covid, Oxford machine learning professor Michael Osborne. I take this as strong evidence that that level of bad experience isn’t vanishingly rare, though he has been well for the last few months, so this is only direct evidence of this kind of thing happening for about two years.
Excerpts from his account:
My own low-points: early on, I collapsed, shaking, and was taken to A&E in an ambulance. A year later, I did not have the energy to leave the house. Formerly, I was a marathon runner, but I brought on a bad relapse with a 700m walk. Many people have it much, much, worse. 2/

Brain fog is a bit like being extremely sleep-deprived—remember, sleep deprivation is literally a technique of torture—but you can't sleep off brain fog. It feels like being lost in a fog, sensing dark shapes shifting around you, losing yourself. 6/

"Fatigue" similarly does no justice to the experience. Fatigue means there is less of you. You are less. You can't, just can't, get out of bed. This is not psychological (although fatigue may cause depression!). Your body, physically, does not have the energy. 7/

(Another distant relative in my generation just told me that they have long covid, but I take that as much less evidence, since I only know about them having covid at all because they saw this long covid discussion.)
C. Rates of ambiguously-maybe-quite-bad symptoms seem very high, even for people who only had mild covid
This norwegian study, n = 70k, has, for mild cases (in a sample mixing people who had covid 1-6 months prior with people who had it 11-12 months prior):
10.2% with fatigue (6.4% higher than control in the 11-12 months case),
7.1% with poor memory (3.5% higher than previous control),
9.2% with brain fog (5.3% higher than previous control).
6.9% with shortness of breath (5.6% higher than previous control)
These numbers are for unvaccinated people; I’d maybe reduce them by a factor of two for being vaccinated, deferring to Matt Bell, who reasons, “A very recent report from the UK claims that full vaccination cuts the risk of lingering symptoms 28+ days after catching COVID by roughly half”.
This meta-analysis of 81 studies finds:
“Approximately 1 in 3 individuals experienced fatigue 12 or more weeks following COVID-19 diagnosis...
