So, most masks getting worn are cloth masks, unless you have a n95 mask you aren't protecting youself, you are protecting those around you.
It's kind of sad, for the minor inconvenience that a mask is, it only works if people use it at large.
It's tough to get people to inconvenience themselves for other peoples good; kind of like getting people to get flu shots, they typically balance their benefit (not getting the flu) with their inconvenience (getting a shot sucks and i gotta go to the clinic) but ignore the benefits that don't directly impact them.
To me it just seems selfish for me to not use a mask when warranted. The inconvenience to me is so minor and given that roughly 50% of people who are infected are asymptomatic, may not know they have it, and are contageous just makes the stakes high enough that it seems like a pretty straight forward choice. Idk maybe i am missing something in the calculus others are making when choosing not to wear at least a cloth mask when keeping social distance isn't possible.
Wrt wearing n95 masks, i think jf you are going into a high risk situation, it's a no brainer, but i personally just avoid those situations.
Here's some of my thinking.
What are the odds you have an asymptomatic or pre-symptomatic case of COVID right now?
IF you have such an asymptomatic case, what are the odds that you transmit that casually to another person in the grocery store, leading to someone getting very sick or perhaps even dying?
I don't know the answer to that, but I'd suggest it's very low.
Lower, perhaps, than the incremental risk of driving over the speed limit, or of eating a hamburger while driving. Certainly better than driving tired. These are other activities that most people do without thinking too much about it. That doesn't make it right, but it puts the decision in perspective. The potential impact of COVID might be a bit higher.
Perhaps a better example: Pre-2020, if you had the flu and had to go to the pharmacy for a prescription, did you wear a mask in the pharmacy? I've never worn a mask when I was ill. I'm not trying to suggest that Covid is the flu. I'm suggesting that a person who knows they're sick with the flu probably has a higher likelihood of accidentally killing someone through transmission than an asymptomatic person of unknown COVID status.
Again, none of this defends the decision to not wear a mask, but it puts it in perspective for the actual risk you're taking.
