Any doctor who tells a fairytale about how a virus can be stopped by a $5 cotton mask made in China is either pushing an agenda or should have their license revoked.
But that’s just my opinion as a political hack.
I’m just an engineer but also apparently a political hack!
If a chain link fence can’t stop a mosquito, why would a mask stop a virus? The ratios of the mesh and the particle seem equivalent (to me at least). The mesh opening is much much larger than the particle.
Also, if masks do work for viruses, why haven’t we been under some mask protocol every flu season? (Although if I heard correctly, Obergruppenführer Fauci has been making noises in that vein recently)
Personally, I think the purpose of the mask -- on the other person -- is to prevent them from hocking a luggie on you. For healthy people, virus exposure through the air is probably a good thing. A small amount of virus floating in the air, once it enters your body, stimulates your immune system to create the antibodies to defend you against disease quantities of the virus. You become an asymptomatic case.
A major exposure, however, may overwhelm the body and produce significant disease before your body has a chance to develop the antibodies.
I advocate for symptomatic people to stay home, but wear a mask if they venture out in public. It's sad how many sick people -- flu or otherwise -- show up to work or school coughing and feverish because they have to, or because they think they have to. I'm hoping this scamdemic will help reduce the cultural need to share one's illness with others.
