Wouldn’t you need 7 billion masks, daily? I think they’re wear once and dispose- the inside and outside will both be covered in germs...
Naw they are worthless after they become damp. 10 to 30 minutes max, multiplied by 16 waking hours a day.
Edit: I am not shaving my beard, a mask will have no effect.

Here's reality. Right now healthcare providers (doctors, nurses, techs) on the front lines can't get what they need because of sheeple hoarding.
Construction crews can't get what they need for fine particulate mitigation, asbestos mitigation, and so on.
It's a tragedy of people who can't do math and don't know anything about anything yet somehow survive to adulthood.

Lets say you're one of the "lucky" who avoids it, are you wanting to wear that mask every cold season for the rest of you life?
I for would rather be one of the 99% who recovers from it and could fight off future infections.
I would even say, if I called you a coward ripped the mask from your face and spit in your eyes, I would actually be doing you a favor by saving you from a life of fear. Unfortunately for you, I'm content to sit back and watch you suffer through a hell of your own making.

Could mandatory face masks in public stop this pandemic?

"Thus, SARS-CoV-2 belongs to the betaCoVs category. It has round or elliptic and often pleomorphic form, and a diameter of approximately 60–140 nm. Like other CoVs, it is sensitive to ultraviolet rays and heat. Furthermore, these viruses can be effectively inactivated by lipid solvents including ether (75%), ethanol, chlorine-containing disinfectant, peroxyacetic acid and chloroform except for chlorhexidine."

"In 1995 the National Institute for Occupational Safety and Health issued new regulations for nonpowered particulate respirators (42 CFR Part 84). A new filter certification system also was created. Among the new particulate respirators that have entered the market, the N95 respirator is the most commonly used in industrial and health care environments. The filtration efficiencies of unloaded N95 particulate respirators have been compared with those of dust/mist (DM) and dust/fume/mist (DFM) respirators certified under the former regulations (30 CFR Part 11). Through laboratory tests with NaCl certification aerosols and measurements with particle-size spectrometers, N95 respirators were found to have higher filtration efficiencies than DM and DFM respirators and noncertified surgical masks. N95 respirators made by different companies were found to have different filtration efficiencies for the most penetrating particle size (0.1 to 0.3 micron), but all were at least 95% efficient at that size for NaCl particles. Above the most penetrating particle size the filtration efficiency increases with size; it reaches approximately 99.5% or higher at about 0.75 micron. Tests with bacteria of size and shape similar to Mycobacterium tuberculosis also showed filtration efficiencies of 99.5% or higher. Experimental data were used to calculate the aerosol mass concentrations inside the respirator when worn in representative work environments. The penetrated mass fractions, in the absence of face leakage, ranged from 0.02% for large particle distributions to 1.8% for submicrometer-size welding fumes. Thus, N95 respirators provide excellent protection against airborne particles when there is a good face seal."
Depending on the manufacturer, N95 protect down to 0.1 microns.
0.14 microns is equal to 140nm (1 to 1000).
Yes, some N95 very much do protect you from this virus when used correctly.

Not arguing with you .. at all. Just warning that people that do get infections while wearing masks, usually become infected when removing the mask.

I don't think there are enough masks to give each person say 10 masks each, so presently there are not enough masks and with the price gouging going on with what there is presently.
face masks won't stop you from catching the Corona virus, but if you're sick it will greatly inhibit your ability to spread it
