No, because they test people regularly and do accurate contact tracing. Thanks to a favourable regulatory environment and a profusion of capable people, South Korea scaled up testing and tracing capacity very rapidly. Furthermore, they were socially prepared to do the basic social distancing.

Also, Taiwan has done an excellent job, and they didn't need to perform nearly as many tests. AFAIK there hasn't been a single additional confirmed case in Taiwan for the last three days.

Taiwan also has a lot of preventative measures, i.e. mandatory mask usage in mass transit systems, government issued masks and mask rationing system, automated temperature checks at various public spaces, mask usage in schools, plastic dividers at restaurants... on top of that they have a very sophisticated scalable method of tracking people who have the virus and ensuring that they are abiding by quarantine rules via tracing the location of their cell phone.

In my city, people are still arguing whether or not people in the mass transit system should be wearing masks.

what are the arguments against wearing masks on transit? i’m no fan of masks, but wearing them on mass transit (of any kind) makes sense. lots of random people in a relatively small, enclosed, and cramped airspace elevates transmission risk materially (as opposed to wearing them outside, where it’s negligible).
