Yeah.
An off-beat thought is that California Chinatowns are less related to Wuhan, where the virus sprung from.
California Chinatowns were formed from RR workers of a century ago. I believe they came from mostly coastal provinces of China.
The counter to that is that there are many more recent Chinese immigrants thanks to the University of Chinese Immigrants (UC Irvine) and the many Chinese in tech in Silicon Valley and surrounds. The Chinatowns are, I think, irrelevant.
