They need us to believe that "viruses" are deadly. I don't think so, at least not most of them or for healthy people. Compare a virus to an "exosome". Viruses may represent cellular signals. To me, it seems like "programming updates" and/or detox programs.
I think wicked people may be thinking to try to use them to manipulate us on a cellular level. That would be done by injection (vaccine), however. The real bioweapon would be a vaccine for coronavirus, not an exosome/virus floating in the air or on a door handle.
There are problems with that, though. Remember the early disasters with trying to correct defective genes? A vaccine for coronavirus would kill a lot of people.
Did you know that the "Spanish flu" was apparently started among Kansas military recruits who were vaccinated by a Rockefeller trained doctor by the name of Frederick Gates?
Also, electromagnetic waves (5G) can cause skin cells to synthesize "coronavirus" according to a letter written to a journal recently. This could have multiple implications.
