You presumably forgot the "</sarcasm>" or ";-)"? In case you were serious, the reason things are working out, more or less, in China and Europe is that measures were put in place (and people have stuck to them, by and large) such that the incidence of new cases fell a lot. Second half of the year in the Americas look less promising. EDIT: replaced summer and fall by second half of the year, given that half the Americas are south of the equator...
