Japanese don't all wear masks but it's the cultural norm that if you feel bad you wear a mask. I would think that custom would help stop the spread.

It's not necessary that everyone wear masks, only the people that have COVID.



Fair enough, but most cases of COVID are largely asymptomatic and the infectiousness has its peak right before symptom onset.


Yeah, and ever since that became clear everyone has been wearing a mask pretty much all the time.

They might be sloppy about it and hang it halfway down their nose, but they still won’t be seen without one.

Until summer anyway, now it’s just too hot, but the heatstroke count is still way up due to people wearing masks.
