I really don't care what they called the virus either but say they gave it the name COVID-19 Delta. It had unique properties, flu like in some respects, different in others. I had it for about 10 days. On day 3 I knocked it out with Ivermectin and Tetracyclines. Was dosing up the vitamins the moment I started to feel like I was coming down with something.
The only people I know with "long covid" have been fully vaxed. No one I'm aware of that was unjabbed has shown any signs of "long covid".
