Mask wearing countries death rates are 100 times lower than the worst hit countries

The top 5 worst hit covid countries right now are Belgium, UK,Spain, Italy and Sweden with deaths per million population from 500 (Sweden) to 836 (Belgium). The highest death rates in a mask wearing country is 7 (Japan) and 5 (Korea). Sweden has a social distance culture so falsely thought they would have a low death rate. So it looks like wearing a mask is 100 times better if everyone does it than just relying on social distancing. Or maybe it is the culture -in Asia the virus is taken more seriously than elsewhere. Or perhaps it is the weather. Or use of technology to track and trace contacts. Or all 4.
