There is strong evidence against that, based on retesting flu survey samples collected in Seattle in Jan/Feb 2020. https://twitter.com/trvrb/status/1249414291297464321
I basically figured since my symptoms aligned 100%, and also since I live and work near the largest casino in the Bay Area (which is a hub for tons of international travelers and people from SF Chinatown) that Corona was circulating around Wuhan in Nov, and made it to the Bay Area by December, and I caught it early Jan.
I still think that's a possibility, but it does seem like it would have made it to Seattle before mid-to-late February in that scenario.
Anyway, thx for the info.
