From the article: “Scientists in Italy claim to have detected evidence of Covid in blood samples taken as far back as September 2019”
Wife and I became ill on what we’re fairly certain with COVID while on a cruise out of Vancouver in Sep 2019. We became ill about three days after flying through Seattle to Vancouver. FWIW, Seattle/Vancouver are main ports of entry for Chinese visitors. Took us a couple of weeks to fully recover.
I think the virus was spreading at least a couple of months before this athletic event.
I had something in mid November 2019 that would appear to be the Wuhan. I literally could not smell wet gasoline on my finger, among all the other symptoms.
I can see the planes at DFW airport from my work.
