You wear a mask to prevent your covid infected droplets from making your neighbor sick. And to a lessor degree, to keep your neighbors droplets out of your mouth.
Of course the tricky thing with covid is, you can be an asymptomatic vector.
But we’re coming to a day where enough of us are vaccinated or previously infected, so that won’t be much of an issue. I’d bet we shed the masks for good next spring if we don’t have a signifigant 4th wave this winter. Which I am hopeful we won’t.
you wear it for no reason beyond political virtue signaling. its useless. unless of course you wear a surgical mask, wear it properly, and replace it any time you touch it. in which case you do get a very small benefit in not spreading your covid.
I still can’t figure out why someone would want to get a disease and then treat it, rather than prevent it in the first place. Does that work with other diseases? I’ll get obese and then have a gastric bypass. I’ll get Lyme disease and then take doxycycline. I’ll get an opioid addiction and then take Suboxone. I’ll get COVID and then take molnupiravir. These treatments don’t magically reverse or prevent all long term effects of the disease they address.
Fits with the zero-accountability short term outlook/instant gratification society we live in.
