You made it sound like 66 people contracted it overnight, but that is not the reality. 66 were identified overnight, period. There will be many more who test positive, while an even larger percentage will test negative. This is why these measures, recommending people stay put and only venture out for necessary reasons, is to slow further spread while testing is now being made available. The reason I believe my statement is because I believe this virus reached our shores before we even knew it had. That coupled with the obvious incompetency of the CDC to act, first to create working test kits and then getting them in mass production. Instead they parroted WHO and argued against President Trump when he canceled flights from China very early on.
So you can be sardonic if you feel the need. I guess facts are your enemy, not your friend.
