I’m not sure how on one hand the author can discuss how contagious the virus is, while on the other believing there were only 250 total worldwide cases on 1 Jan after the first case was discovered in November.
In a city as densely populated as Wuhan, within a country with as many densely populated cities as China.
Given that, I’m also not sure how the author concludes the virus first entered the US “around” 15 Jan - the first *known* case.
That said, I think its mostly even-keeled...but hey I’m just a dumb pilot, not a Ph.D in biology.
