You need face masks almost anywhere these days. Without them you are kit allowed to enter stores, offices or restaurants. So we all need them, there is no way around it. Which doesn't mean we need to buy them. Face masks can easily made at home out of old clothes. One good thing from making masks yourself is that you can wash them at home and reuse them. The cheap hospital masks can't usually be washed and have to been thrown away eventually. A home made mask from cotton can be washed by 60C+ to kill the virus.
Cloth or fabric mask is still a good thing to have when you go outside because it still helps ..............
Only two ways of getting a virus, injecting with a needle or mosquito. How on earth will a mask or shield (aka battlehelm as worn in war) prevent a mosquito sting. Malaria would no longer exist.
