I think you're definitely on the early curve. My timeline is pretty distinct in my head, because I had a family trip planned on March 15th. I remember the leadup very clearly:
March 1-2: Hey, should we be worried about this coronavirus thing? Nah, seems fine.
March 2-9: Hey, should we be...
March 9: Hey, should we actually be worried about this coronavirus thing? Ehh.. it still seems pretty low-risk.
March 10: Y'know, there's a decent number of cases in <place we were going>; maybe we should hold off just in case?
March 11: Oh, this isn't just my vacation -- my school is closing too.
March 12: Oh boy. This is gonna be a big deal.
That March 12 date sticks out for a lot of people I know. Even as someone who was tracking coronavirus as early as January, I just didn't think it would be that big of a deal until March 12.
