SARS-CoV-2, probably released in late May 2019, in Chinese communities within Italy, by mid-summer 2019. Diagnosed as “a summer flu.”
Probably already in the U.S.A. by September 2019.
- my guess
Merely gossip, but a friend who lived by the Port of Los Angeles said people there were getting sick in Fall 2019. Given the volume of shipping from China, this seems plausible to me.
