My theory is that in the US this is hitting the rich people first. Probably due to the fact that only the well-off do trips to China and northern Italy.
In
Montgomery County PA where I live they have a map of cases and one township currently has more than double the numbers of cases than any other township.
It's Lower Merion township, where all the rich folks are!
Delaware County has a similar map and it's Radnor and Haverford where all the rich folks are... but then, Upper Darby where there are no rich folks at all, so it broke the streak.
Chester County, it's Tredyffrin and Easttown right down the main line from Montgomery's Lower Merion.
In all counties, the rich people who live out in the sticks seem protected.
