The problem is that even after reading this, covidiots will continue to wear it. Like a scientist said: "wearing a mask to stop viruses is like building a fence made of chicken wire to stop mosquitoes from entering your garden".
[Roughly translated from Japanese]
Before you get scared, let's take a look at this infographic. Wearing a mask is scientifically effective in preventing viruses but not perfectly.
Let's compare sizes. Virus are 0.1 μm micrometer. The pores of masks are 5 μm micrometers. (The pores of the non-plying mask are 1-3 μm micrometers)
The pores of masks are 50 times that of the virus. (Woven fabric masks are 10 to 30 times larger than that of virus). Viruses effortlessly pass.
For example, the human body is the Japanese archipelago. Bacterias are basketballs. Viruses are tennis balls.
