My suspicion is the long term health implications have been greatly overstated.
With high background rates of anxiety and saturation media coverage, lots of weird things will be put down to COVID.
There will also be enormous publication bias (professional and mainstream media). Someone saying they have persisting XYZ will get reported, no matter how implausible any link.
if you doubt the power of these phenomena, just think back to that curious 1980’s Australian epidemic of RSI.
