Yea, I would think avoiding places like airports, train stations and the many other places that are subject to lots of human traffic make sense to stay away from.

I see one big issue we all have to face, everytime they talk about social distancing, the next picture often shows 100's of people in lines at grocery stores.
So they have shut down theatres, concerts, sporting events. Even restaurants are only offering take out options. But you can still go to Costco and load up with everyone else.
The spread of this will be very difficult to contain.
