Frankly, does it even matter now? With the US cases rapidly approaching approaching Italian numbers the horse is out of the barn. I'm afraid there is no going back and the US (where I live) is in for a rude shock in the next two or three weeks. We've jumped from sixth to third in the number of reported cases (26,000) and that's probably only because the US is finally starting to test a lot of patients. We will see a doubling in four to five days and this is exponential, not linear. The 'spring break' partying going on down in Florida will only speed the spread. Good luck to us all.....
