Earlier quoted context omitted.
There were just 2 cases detected at the gym down the street from me. I'm in a medium town of about 40k in upstate NY. Not podunk, but hardly bustling. I'm considering the USA fully seeded at this point.
Does this mean we need a more robust domestic response to contain coronavirus, instead of or in addition to restricting travel to the US? Akin to how securing a network is more than setting up a firewall at the perimeter.
At this point, the only rational thing to do is to try to slow the spread. The good news is that this is a very mild virus, and the vast majority of infected people will have minor symptoms. The fatality rate in Korea is currently 0.6%, and becuase of the comprehensive nature of their testing, this should be considered the upper bound on CFR.
