Yes, exosomes seem to be the truck and trailer to get all sorts of compounds from cell to cell including viral material.. And covid can spread that way too. Presumably the injected mRNA, plasmids SV40 mammalian gene expressor and whatever else is in the junk list can be moved too. SV 40 was a very tricky virus, because it became a "stealth" virus, hiding inside other viruses as well.

Polio viruses use exosomes as well. pubmed.ncbi.nlm.nih.gov… Polio though,

is interesting, and a slightly different "animal" to covid, in that 99.99% get asymptomatic infection and immunity. Where I live, that rate was excessive... in the worst polio outbreak the clinical infection rate was 1/5,000. Poliovirus also requires other co-factors in order to get a foothold into the mucosal. It was no fluke that the old sprays, lead arsenate etc, and DDT had co-factor roles in exploding clinical infection numbers in the 30s - 50s. Dr Benjamin Sandler was correct in his book about polio and advice to parents to cut the sugar, because sugar + LPS potentiated the virus as well.

For all we know, those factors might also operate with covid infection as well. because a person who eats a lot of sugar blocks the transporters which also supply the body with vitamin C.
