I watched a really good documentary, I believe by Vice, on the origins of COVID-19. I will try and find the video (it was on YouTube for sure) but it explained delicately and without being racist the origins of the virus and also the history of wet markets in China.
I believe in the documentary it explained it came from bats and because of the way in which the dead animals are stored in the wet market (primarily in cages) the 'fluid' of the bats etc would have leaked onto other species, like pangolins, and infected that way.
However, I have watched other documentaries by *evidently* anti-China media outlets who suggest it comes from a lab but there really isn't much evidence to corroborate that. I think for the latter explanation, it's very much a situation where if you will for it and try hard enough to see it, you will link the Wuhan lab to the virus - despite the logic being inconsistent.
I have a lot of friends in China and I was speaking to one of them through We Chat and she said to me that the timeline we have seen from China is a lie. She couldn't say much more because her account would be locked otherwise.
