It's more needed if there's a high community transfer - so if many have it and are maybe asymptomatic they don't become a spreader.
A poor filtering or fitting mask protects others - not the wearer - so places like asia are all wearing masks to prevent the spread if worn by the sick (or those people that have it but have no or mild symptoms).
