who wears masks in Asia for sickness besides Japan? most of the masked people in Asia wear them to protect themselves from extremely polluted air where these masks can work against wrote big particles compared to viruses and obviously people in clean Europe and relatively clean US no need to wear them to breathe clean air, which is luxury especially in China and India
No, they are not. I've lived in China for years and only very small minority of people worn masks against pollution prior COVID. I've also travelled all around Vietnam for weeks and it was extremely rare to see someone wearing mask prior COVID (even more rare than in China). So stop this misinformation about decades of their use in Asia (outside Japan) for health reasons. You sound like someone who never been to Asia and just repeats nonsense read somewhere.
