I think COVID-19 is turning out to be an epithelial syndrome based on the virus binding to the ACE2 receptors in epithelial cells and disabling them. Shutting down the ACE2 receptors is resulting in a cascade effect that ends up causing O2 oxidation and oxidative stress.
The oxidative stress is what is damaging the organs, causing blood clotting and strokes, causing breathing issues due to low oxygen absorption within the lungs, and ultimately organ failure as the body's goes through antioxidant depletion from runaway free radicals.

SARS-2 is primarily cardiovascular. That’s been known for about two years now, virtually from the start. PubMed is filled with papers to that effect. Freepers don’t read PubMed, they prefer kook sites.
