Asia is a big place. Bigger than Europe and North America combined. Not every place has the same rules. Pretty sure Dubai has different behaviors when it comes to masks than Singapore. Here, they are officially discouraged, though with the PM's speech yesterday, that is changing. But by no means is it a rule. However, it is considered courteous to wear one if you are ill, to help prevent infecting others. And an N95 mask, even worn imperfectly (as long as it covers mouth and nose) will help with that. It will do nothing for protection of the wearer, and most folks here know that. But they wear them to protect the community. And there are of course some that stupidly horde them...they were hard to find for a while, and the govt had to threaten prosecution for profiteering (may have even made some arrests). But for the most part, the percentage of people wearing them is not much higher than it was a year ago. And with the new rules in place (no retail aside from food, etc), there will be much less traffic. The govt had been slowly add bits to the shelter-in-place and no-gathering rules, but that was accelerated yesterday. My theory is the speed up is due to the fact that they confirmed a case in a bus driver. One bus driver. And that was the last straw to close down nearly everything. Prior to yesterday, schools were still going, gatherings could be up to 10 people, all stores were open...even the rink was doing public skate (but no league or shinny). Today, rink and all stores (except food and essentials) are closed, schools are shifting to online learning by Wednesday...all because they ID'd one bus driver with nCoV-19. Well, and we cracked 1000 cases, and had our 3rd death.
