Awesome in depth response! Yes, I was hoping this post to serve as an initial alarm bell to look further into, rather than being definitive advice based on a comprehensive literature review.
I can’t respond to everything, at least not at once, but here’s some:
categories of ‘at least 12 weeks’ and ‘at least 1 year’ do overlap, right?
I think the different waves may have had different underreporting factors, with least underreporting during Delta, so we can’t take those rates at face value, and I prefer using estimated cases whenever possible
The wording is “less than 12 weeks” rather than “at least 12 weeks,” so the categories shouldn’t overlap, time wise. Under the theory that omicron is underreported and delta more accurately reported, this bolsters the case for long COVID being linked to disease severity—with the caveat about the percentages not adding to 100% in mind.
Uhm, no? I’m quoting you on the middle category, which overlaps with the long category.
I see what you mean. The study’s criteria, which I didn’t quote here, states that the earliest time at which the respondant met any of the conditions for a COVID infection should be counted. I remain confused (not by you, by the UK study)!
Also, there’s no need to speculate, because there have been studies linking severity and viral load to increased risk of long COVID.
I don’t see myself as speculating, so much as emphasizing that contradictory evidence exists even about the association, not to mention causality.
