I was there in January and February and had my temperature taken routinely to enter populous shopping areas, tourist-packed areas, transit, etc. Mask usage was mandatory in some cases, like buses. They ensured they had sufficient inventory of masks, and even published it so that you could look up which pharmacy to go to. There were lines down the block outside of them, but they also had a reliable ration available for anyone who would wait.
State-side, I haven't had my temperature checked once. Even when I reentered the US, there wasn't so much as a thermal camera to walk in front of (that I could see, anyway). This was the procedure upon entering both Taiwan and transiting through Japan all the way back in January when cases in Taiwan were in the single digits. I can't even find a single mask here.
People were sensible and conscientious there. People voluntarily cut back their social behaviors, but they haven't enacted a hard shut down. It seems to me that we just haven't implemented any common sense behaviors and expect Trump/the governor/Fauci/whoever to come up with some genius plan to solve the crisis for us.
