Your paper literally says surgical masks are working.
Stop trolling you fucking retard.
Surgical masks are worn by surgeons when in the operating room.
Unless you are claiming that surgical masks are available for the general public.
Have a gfy day!
Going to a hardware store you can get even higher grade masks then what is used for surgeries lol.
Whatever prevents the spittle of your stank breath from reaching far and wide is always going to be helpful. Some things more than others.
A bandana is not the best but is still better than nothing at all. If you're healthy it could spare you from inhaling someone's infected spittle
And if that someone was also wearing a covering then all the lower risk
It lowers the risk. It does not totally eliminate it. You lower the risk even more if you only go out when essential. Maintaining a distance doesn't eliminate the risk but lowers it
All these steps work to reduce the r value. Get that to less than 1 and the virus dies out.
Don't give a fuck and well, look at America vs new Zealand or something.
