One question here: Do we have any scientific way to verify which strategy works? I been waiting for related research that can either proof or disproof the usefulness of the "Lock-down strategy" which China been using in the past couple of months and still not fully lifted. We had little less than 30 total cases in our city with just over 1 million population, and the city was in lock down mode for few weeks. I can feel the slow rise of living costs during that period of time. It's quite funny to see how people reacts to this, panic-buying all the face masks for example. Makes me think whether or not it's worth it to go full-out panic, because panic usually creates way more chaos/problems than the problem itself.
