The West really should normalise wearing masks when you are ill. Japan, Korea, Vietnam, Thailand, it’s very normal to wear a mask even if you have a slight cold.

That way, you are not “the person” wearing one, but one of the many taking other people’s health seriously.

If I am coughing, sneezing, runny nose, fever, etc. If I have any symptoms at all I stay home or wear a mask. A lot of people do.
