I had three retailers Chinese were doing same thing here.
Had the public had masks here, like the Chinese, and worn them we might not have overtaken China’s number
of cases as we did today.
Masks do not totally protect the wearer, but they do reduce the viral load, thereby allowing the wearer to possibly build up immunity rather than being overcome by huge jolt of virus.
As I understand it, that is one way SK has keep their own epidemic from running completely wild.
