I did a search, but did not see this yet. I think Dr. Drew has a great take on this...twice:

Unless he's changed his tune from the previous statement, he's missing the point.
It's not about the case fatality rate.
It's about slowing transmission so care of the most vulnerable can be managed.
The official who spoke right after Trump nailed it: we want to lower the travel to and from the most affected areas.
At this point I'm not cancelling my travel unless specific circumstances dictate it. I will cancel them if recommended by public health officials, or other factors that concern me. But it will likely require some people to stay home or avoid some events, or they are going to be indirectly responsible for those more seriously affected.
