It’s the same kind of disease - an endemic seasonal virus.
We can agree on that, right?
The flu is dangerous, just look up studies, we’ve been researching this for decades.
Any viral disease can potentially turn into a ‘long’ disease. Long covid is just a meme at this point with a lot of people ‘having’ it with some unclear issues, and only a small subset of them actually having verifiable issues.
‘I got the covid, and now I have brain fog!’ - yes, or you might just have a psychosomatic issue because nocebo.
I do agree that there are people that actually get terrible symptoms over a long while.
