Obviously viruses are minute, but as you just alluded to, they leave our body on droplets, so the size of the virus size isn't as important as the size of the droplets. Droplets that leave the body have a wide range various masks, whether it is an N95 mask or a cloth mask has various levels of ability to reduce the range of these droplets. You combine the mask with social distancing and the risk factor greatly decreases. Let's not ignore that large droplets come out of the mouth even when just talking.
I won't quote you on that because 95% of particles are blocked, which is why its classified as N95.
Obviously virologist wear significantly better safety equipment, but they idea is you do what you can to protect yourself from airborne particles. As far as Stoney goes, does Stoney study diseases? Otherwise, I will defer wear I get my information to the experts who do this for a living.
I got vaccines for those diseases and I'd expect that everyone else would get a vaccine as well to reduce the risk of spreading the disease to others. Almost like wearing a mask will
reduce the risk of spread.

It's simply about risk reduction and if all it takes is to social distance, wash your hands, and wear a mask to reduce the spread, I just don't understand why that is such a challenge for some.
