Seriously, did you think this was some type of "gotcha" post? PPE in those settings is intended to help decrease infections spread through bacteria, spit, blood splatter, etc. Do you understand how small virus aerosals are? If the original thought about how the virus was spread was correct, such as large droplets (hence, 6 feet rule, which is practically worthless against aerosol transmission), then masks would make a significant difference.
Here's the PPE you need when dealing with aerosals. How many people do you see walking around in this?
Hint: Even a properly fitted N95 mask will only stop a small percentage of aerosols that the virus travels on. A vented N95 or N95 with small gaps that air escapes from is practically useless. How much good do you think a surgical mask or cloth mask is going to do?
