"For almost a year we are asking ourselves does Covid-19 have a reservoir or an intermediary host, we worked so hard, [practicing] One Health, we haven't found anything." "For some other viruses, it's so easy to find the intermediary host." [Mers - dromedary, Ebola - mammals, hedra -horses, nipah - swine, lassa fever - rodent] "Yet we tried so hard and we haven't found anything for Covid-19. That makes me think about in a one health setting, is HIV really from a monkey? We know HIV is so close to SIV, but HIV has never been SIV, they separated -we don't know how long ago. But they separated a long, long time ago. Maybe the Covid-19 virus also separatedfrom a bat virus a long, long time ago. We might not be able to find the intermediate host. We have to rethink our theory or hypothesis about the [inaudible perhaps Gao says - logic] of viruses. People think it's closely related tothose monkeys, but the virus has never been the same. This is why we have more questions than answers on the origins of the Covid-19. For any other virus it's so clear, for the Covid-19 we have so many questions remained. IsCovid-19 so easy to be transmitted through the package of the seafood, long distance package, why is that - wedon't know? This is something new. It's a scientific question." (Webinar, part 62)
