Literally doesn't make any sense.

What? This virus has a three month latency period that suddenly flips a switch and everyone and their brother get sick at the same time?

No, if it were here in November, then we'd of been going through this in the same time as China. Instead, we were two months behind. Which means that the virus was delayed in getting to America. Hence Trump's banning of china travel.

The virus had to stop over in Europe before finally hitching a ride here.
