Thanks! I’m curious what you think of his argument that if debilitating long COVID were common, that would be obvious anecdotally and in aggregate statistics:
Every week someone comes in and says things like 30% chance of brain fog, but think about that for a second. Half the country has had Covid. So this is saying 15% or more of the population is suffering from crippling brain fog? Wouldn’t we know? I mean come on.
I’m overdue for making another pass through the latest data, so my opinions on this are weakly held. But briefly: my current thinking is that many people (including Zvi and me) have made the mistake of conflating a number of different phenomena into the single category of “long covid”. I believe Zvi is correct that if a large number of people were suffering long-term debilitating impact, we’d know it.
I suspect that after I plow through the data again, I’ll update significantly in the direction of believing that:
“Long covid” is a debilitating phenomenon that affects a very small number of people for a long time.
“Post-acute covid” is significantly impactful and impacts a non-trivial number of people moderately for weeks or maybe a few months.
Anecdata: I don’t know anyone who’s been profoundly impacted by covid for a very long time. I know multiple people who’ve suffered significant impairment for weeks / months.
The impact of long covid is (small incidence #) x (large impact #), and the impact of post-acute covid is (medium incidence #) x (medium impact #). I think for most people, the total expected impact of getting covid will be somewhere between a day and a few weeks of useful live lost, with large error bars and much of the impact being in low-likelihood events.
