The virus theory has some big flaws, so to say, it is debunked as junk science. But as we all know, there is contagion. What is causing it? The debris of some others? Yes, I would say, but how? An overload that our bodies can't handle? And does a sneeze of your neighbor cause it? The truth is, it is the Myon neutrinos. They go thru everything, concrete walls everything, by the billions. So, if you are exposed to a sick dood, next to it, he well send his neutrinos to you and vice versa. You get sick, when your body gets an overload of "bad" neutrinos. So contaigon is done on a subatomic level. That is why we should stay away from people who send out bad vibrations, i.e neutrinos.
