It is immeasurably easier to tell a population that has a historical high usage of face masks to do so all the time and achieve compliance. Not so here, where 3/4 of the population think Corona is a hoax.Actually, I have. I also have many relatives spread amongst Asian countries (Does not make me an expert). Yes, face mask wearing is more common than the west but it was usually worn when people are already sick to prevent others from getting infected. It’s a bit different with covid-19 since a lot of people are asymptomatic for long periods of time. Now it’s compulsory to masks all the time in public. It’s all about reducing the spread of infection.
If you ever been to a Far East nation you will know how dense the cities are, there’s no way social distancing works there without the country operating normally. You have to wear masks to prevent people from breathing and coughing right by your face. South Korea, HK, Singapore, Taiwan faced the initial outbreak and curbed it without draconian lockdowns. All pro face mask wearing.
