I don't think so unless you make a lot of assumptions. That it was a variation that is just as contagious. That it was a variation that could cause as severe symptoms. That it even came from humans. All samples from January 2018 to December 2019 came out to be negative for the presence of SARS-CoV-2 genomes with the exception of March 12, 2019. Why just one month and then nothing for so long before the outbreak? Per the study, sewage includes rainwater from open drains. A highly infected bat could have ended up dead in a sewer. Nature is full of unexpected possibilities.
I bet there are other assumptions without which it doesn't call into question what we think we know.
- mark-r 6y agoI don't know how they do things in Barcelona, but in the US the rainwater has its own sewer system. If it didn't the waste water treatment plants would be overrun every time it rains.
- roywiggins 6y agoCombined sewers are common in the US. https://en.m.wikipedia.org/wiki/Combined_sewer https://en.m.wikipedia.org/wiki/Combined_sewer
- mark-r 6y agoMy understanding is that combined sewers are being phased out whenever possible for the reason I gave.
- VBprogrammer 6y agoI'm not sure how much you know about Barcelona but it's an ancient city who's history can be traced back through to the Neolithic period with very narrow streets designed before motor vehicles. It's not really compatible to any US city.
- roywiggins 6y agoThey have exactly that problem, but it didn't stop dozens of American cities being built with them.
- tchaffee 6y agoIn my original comment: > Per the study, sewage includes rainwater from open drains. There are even more details in the study.
- cs702 6y agoExactly. My questions were and are a polite way of expressing skepticism.
