Dessutom, med tanke på hur det exploderade i Bergamo så är det svårt att tro att det fanns något betydande antal fall under hösten 2019. I så fall var det ännu mindre smittsamt då, vilket iofs är en möjlighet.
OK! Samma sak i sydamerika för övrigt, alltså att det gick trögt i början.
The first two samples were on October 30 and November 6, 2019, and turned out to be negative. Thereafter, all samples were reported to be positive from the virus, beginning from November 27, 2019, to March 4, 2020. The viral load, overall, was 5.83 log10 copies L-1, which is similar to the viral loads in sewage studies in France and Spain, as well as the USA, during active infection.
The striking thing is that the first positive sample preceded the first diagnosed case in the American continent by 66 days and the first known case in Brazil by 91 days. In Santa Catalina, the first case was reported only after 97 days. In other words, the virus was being disseminated in the community months before the first case in North or South America was reported.
