Sorry for not being upbeat! I am wondering why the world still does not seem to care about it. Why do we have to wait until every city gets infected? Why we can't stop travelling? Eventually, when it spreads to a city, the quarantine must be the only way... but why we aren't preventing that ourselves? The politicians does not really seem to care (in the bunkers)? Individual, consumer society with no interest and with…
Say for example that your family operates a tiny tourism-related business in South East Asia. A prolonged shutdown of travel between China and your country could literally drive you into poverty, given how dependent some countries in the region have become on inbound tourism from China. Given your extremely remote chances of catching the virus, the risk of losing your entire family income is a much more significant risk to your health.
Because of this, it's important to be balanced in thought and decisions, and not just panic because of what could happen. Where there is evidence to support restrictions, keep them in place. Where there is not, remove them.
Outside of China this issue still remains far less serious than many other health-related risks. The "we need to do something" (anything!) mindset is actively harmful.
