How does a person know they aren't exposed
to the virus at any given moment in time?


By staying home and not letting anyone
inside your home and disinfecting what
stuff comes into your home like food etc.

Many people attempt to do that and still catch the virus.

Only those too stupid to do it properly.

And vaccination may well be possible too.

Not everyone wants an experimental vaccination.

Irrelevant to whether that stops you catching it.

How can you prove something that didn't happen has a causal relationship
to anything that could have been a preventative?

By observing that those who stay home and don't let
anyone inside their home and disinfect what stuff
comes into your home like food etc dont catch it.
