Also Italy and Spain show very similar counts. Maybe because both nations have similar life styles in terms of socializing?
The most surprising thing is Switzerland on the top. One would think, that the Swiss are very law abiding and safety minded and that they practice the social distance recommendations. Why then such a high mortality?
Milan (and the surrounding area) was hit hard, I suspect, because of extensive travel between that fashion center and the fashion manufacturers in China. New York was hit hard because thousands of travelers from everywhere, including China, Milan and other hot spots, arrived there daily. New Orleans got hit because they went ahead and held Mardi Gras, attracting tens of thousands of people both nationally and internationally. Switzerland is a major destination for people who need to do safe, confidential banking, and also for skiing. Many, many Chinese traveled there. The travel/tourist nodes are the one getting hit the hardest.
