re: China just cancelled all flights and trains in/out of Wuhan

It’s entirely possible people from the originating region may have some immunity from this strain. In other words, mortality could rise the further you get from the virus’ place of origin. Of course, it’s not time to panic or really worry too much. In the West, we generally have superior sanitation and better air quality- both advantages.
If the illness made it over here, life would go on. Politicians care about keeping revenue going, not saving lives. The key would be minimizing exposure. Maybe stay home and homeschool the kids for a bit, stock up on delivered groceries and Lysol, tell your doctor you’re taking an exotic vacation and get a Z pack, Cipro, inhalers, etc. for your entire family. None of this will probably be necessary.
