Masks don't stop a virus.
I was a pca for 2 years when I was a student in nursing school.
All masks do is prevent droplets. Meaning water droplets from coughs and sneezes, that's it, nothing else. You need a high end rebreather or a suit with air from a different atmosphere than your current one pumped in to avoid a virus.
If you can wear a mask and can smell things like cookies, perfume, a cleaner, etc then that means microscopic particles from that source passed through the mask, entered your nose and hit your scent receptors telling you what it is. Know what else is microscopic? A virus.
Masks may slow the spread of a virus through a population by a very very small percent, but it will never prevent it. If every person on earth wore a mask 24 hours a day we would all still get it.
