and give each other group hugs and have lots and lots of sex.

a major travel hub and thus self explanatory.

back to China. New York is a transportation hub.

just the first line. Basically look at a map from major airlines. 1st tier hubs, then will spread to next level.

we have a lot of people, international airports/ports/cruise ports.

People come here.. Iowa and similar.. not so much.

..I assume California and NY the same..and cruising is a big industry as well.

The more people living per square mile, the faster it will spread.

not because of "something else".

the places that are testing the most.

at least in Washington State. They developed their own test at UW in February, against the wishes of the CDC.

I at first thought of CV as the affluent disease because no homeless are going to Italy or taking trips anywhere, and it's the travel both international and domestic that spreads these things so quickly. So, yes the largest population areas would be hardest hit initially.

I just went to the CDC website and pulled these numbers. They may not be current.

New York - 6834 cases / 19.5 million people = .035%
Washington - 1376 cases / 7.6 million people = .018%
California - 982 cases / 39.5 million people = .0024%

While California is near the top in terms of cases, it has almost twice as many people as other states, so the actual rate is much lower.
