The problem is not everyone tried to stay in for two weeks. And not just in the urban areas or the coastal cities.
Supposedly, if they are to be believed, when China dealt with SARS; they were able to isolate the virus in a single city. The tried to do that a second time around but failed to realize that they should've been on lock down for a week or two. As a result, it became a pandemic. Again, supposedly, they waited it out and saw the curve flatten. I'm not entirely convinced but still I would be anxious to see how other countries fair by June. I suspect the US's numbers will go up... and international travel from other countries will be suspended. Not from our end, but theirs.
And that's when things are going to really get ugly.
