Except for losing the sense of smell, because thats a fairly unique symptom. All the others are things that happen to people for various reasons, some very covid adjacent, like a virus, and some just random like genetics.
This is all true and useful and factual, but people seem to be leaping to the conclusions that 'covid' is fake, 'long covid is fake' when the only real conclusion is:
'If you have a bunch of long covid symptoms right now, then you are more likely to think you had covid last year than actually had covid last year'. Which is a neat result, but not exactly surprising.
But if you're big on the 'plandemic' then this probably feels like supporting evidence for that, when it's clearly not.
When the real takeaway is 'check for other causes in people reporting long covid' which I hope was happening anyway, even for those with a confirmed case of covid.
Chronic fatigue syndrome (I don't know whether that's generally accepted as a real disease these days but I know one famous person and one real life acquantance that had it) and similar is often triggered by an infection or virus.
I know another person in real life that was briefly unable to walk after a flu caused his immune system to attack his own nerve endings.
It seems unremarkable to me that people getting post-viral issues in the middle of a pandemic might assume they'd got covid.
It's like calling out car crash victims because "hah! It wasn't a car that hit you, you fraud, it was a pickup truck, look we have video evidence".
