Here's one of the latest reports about the accumulative effects of repeated infections after getting covid and how it turns into long covid.
PolyBio-supported study in rats demonstrates that SARS-CoV-2 protein activity drives longer-term vulnerability to another infection, augmenting physiological problems such as neuroinflammation,...

Here is a more indepth tweet thread about it.
You don't need to be repeatedly hit with covid, after the initial infection. It can be anything. Which, in my opinion, explains why people these days are sick, and sicker, more often.

There as been over 24,000 research papers done in 4 years for covid and long covid, the most of any virus condition ever.
This is a good channel if you want to hear doctors talking about research papers and talking about the current theories of how covid attacks the body.

I admit I am more puritanical about the subject as I'm a convert after getting it myself, and I've also seen people writing about killing themselves and some doing it, or arranging appointments for euthanasia.
I think it is as much the psychological impact of becoming disabled over a short period of time, something most people never thought would happen to them. When they don't recover in a short space of time they get depressed and wonder if this is permanent.
My only advantage in this scenario is I've always been disabled, so I'm not suffering from ptsd.
