Ok, so we look for asymmetric deals in life, to reap a high reward for taking a low risk, and/or to find great value for a small outlay.
Can we agree that wearing a mask is a low cost, low risk activity that can help slow transmission of a very high risk, and very high cost virus?
Is that an asymmetric deal?
Please discuss.
No. I for one cannot agree with your primise.
The size of the Covid19 virus bacteria is .1 micron.
The masks most people are being asked to wear only filter down to 20 microns.
Do the math. It is like trying to filter out mosquitoes with a chain length fence.
Surgical masks do not filter down to .1 micron. One would need to use a CDC Type 4 (I believe that is correct) aspirator to filter out the virus. VERY EXPENSIVE!
Masks only give the appearance that one is taking preventive measures. There are people walking around with antibodies to the virus. I know of a least a dozen people who have been exposed--but never came down with it.
EMORY University in Atlanta is very close to vaccine. So are the Israelis.
Wait until flu season is in full swing. If masks are effective, flu cases should be down dramatically.
