Maybe because people don’t feel like taking the risk? Regardless of your watering dawn of the virus, there is a good chance one ends up in an isolation room in a hospital racking up thousands of $$ in insurance copays should they become infected. Beijing, Hong Kong, and Taipei will still be there once all this blows over.

You don’t know what someone’s life situation is at home, therefore you have no authority to judge their decision not to travel.

I’m traveling in a couple weeks and transiting TPE both ways. I’m watching this very closely. I do have an elderly father who nearly died from a staph infection. I may not want to risk bringing home this virus to him. But that’s none of your business to decide for me.
