I suspect it was here, too- I had odd symptoms after a trip in Feb 2020. Pretty mild, but a cough that really didn't go away, and I thought I had a mild fever, too. The cruise we were on prohibited anyone from Asia on the ship if they entered the country less than 2 weeks from the sailing.
Then again, way before that, my wife had a really bad cough for a couple of months after a trip to Puerto Rico in July '19. We wonder if that was an early version.
Based on all of the timing that has been figured out, there's no way that it contained in China when they found it- it had to have flown out well before anyone was aware of how bad this was.
