Are the SARS-CoV-2 post infection / long Covid symptoms unique to SARS-CoV-2 because I feel like there must be some overlap with other previous viruses that have similar effects on humans long after the initial recovery. The well known ones I believe are Post-Polio, Guillain-Barré and more historically more controversial - Chronic Fatigue Syndrome.

I'd say we just gotta be careful with "Chronic Fatigue Syndrome" (like you seem to indicate as well), which is like the name says a syndrome. So basically nobody can find out why and your illness gets subsumed under a "syndrome" that is based on the symptoms you're showing.

This makes it really prone to have different actual causes subsumed under this. I'm pretty sure I could've been diagnosed with this if I had continued talking to doctors, being sent from one specialist to the next. In the end I figured out what caused my fatigue myself and I'm feeling better than ever. This was way pre-Covid btw.

Can you share your methods for finding out what caused your fatigue and optionally what you found out for yourself?

Chronic Epstein-Barr Virus (mono, stays around in, say, the liver).
