Later research on the Covid 19 virus showed. that one reason that covid was so virulent was because it had a never seen before ability to hide from the immune system for a critical 36-72 hours which allowed the virus to achieve critical mass viral load for serious infection before the body recognized it was present.

If you happen to remember any links for this one, I'd love to read them.

HIV, herpes simplex and some other virii have an abundance of arginine over lysine which allows the virus hide in lipids. Since the human brain and neurons contain lots of lipids, these virii take up residence there.

Th spike protein in Covid-19, compared to other corona virii, also has the arginine vs.lysine abundance, including on the critical HIV gp120 sequence that does not appear in natural coronavirii.
