First, we still don't know the origins of Covid-19. The most accepted answer is zoonotic origin but there are problems with that, namely that Wuhan is far from the suspected bats and there is no documented case of Covid-19 in any wild population. The other competing theory is the "lab leak" family but again there's no evidence of this eitehr. Research and findings of Covid-19 in Italian sewerage suggest that Covid-19 might've been circulating in Italy in 2019 [1]. So another possibility is that Covid-19 resulted from forming a virulent strain in a person who was infected with multiple strains at once [2]. We may never know the true origins of Covid-19. So with asymptomatic spread and a novel virus, it's unlikely that whatever China did actually mattered at all. Once cases reached the US in particular, it was game over. People just can't miss work. There were very few places that maintain zero Covid for any significant period of time (eg Australia) through a combination of luck, geography and extreme quarantine. By geography I mean Australia doesn't have any land borders. And even then it only lasted so long. | ||
