The masks don't help with this virus. It is smaller than the holes in the mask. That's why the N95 masks were reserved for health care workers, those masks DO keep that virus out.
The virus itself is smaller than the holes in a cloth mask, but as i said in other comments there is a lot of indication that it is transmitted in water droplets. That the main spread case in South Korea was at a church where they were doing something which involved spraying. Or in italy where soccer matches where crowds scream and yell was a super spreader.
And this is intuitive, we know a sneeze with its moisture will release the virus and you dont want to be sneezed on by a sick person, that person cover there sneeze so the germs dont go spraying everywhere.
That the virus is attached to moisture and the masks reduce the emitted moisture, so in enclosed spaces like subways or even stores, people wearing masks reduces viral load in the air by reducing moisture and fewer people will contract the virus. It does not eliminate it but it slows its spread. That's why all these mask wearing countries- japan, South Korea, taiwan, have slower spread, japan did not even have lockdown, what they do different is the majority wears masks.
They also do not have a culture of close contact. They don't typically use handshakes, they bow. They also tend to be more fastidious than Western countries.
