A foreigners perspective, the Asians see it differently, many Thais wore masks before the pandemic ever started. They don't have the same aversion to masks as people in the west.
I did a border run down to PB on 5th Feb 2020. There was temperature checking, hand gel, and virtually everyone on the train wearing a mask, long before the west even talked about it.
I fail to understand the western reluctance to caution, it is a case of Gung Ho and hope for the best.
