Can you name another pandemic where the origin point had a BSL 4 lab actively studying that exact type of virus while the likely zoonotic reservoir was 1000 miles away?
In a vacuum a zoonotic explanation is always far more likely but this isn’t a vacuum.
So that’s a no then, great. Coronavirus outbreaks aren’t novel. This is the third major one. Sane people should be able to agree that your theory isn’t more probable.
It’s not. We’ve had two other major coronavirus outbreaks (SARS and MERS) in the past 20 years. The presence of a lab studying these viruses, in a country that already had one major outbreak, does not mean it’s more likely that the lab was a source.
1977 H1N1, a few small pox escapes, an equine virus in Colombia, a SARS escape, foot and mouth disease.
Likely some escape, not terribly unlikely pandemic:
With this higher number, which we take as a worst-case scenario, the likelihood of at least one escape from 10 labs in 10 years becomes 91%, almost a certainty. It follows that, if the likelihood of one LAI leading to a pandemic is 30% in the worst-case scenario, the likelihood of an LAI-caused pandemic resulting from this whole research enterprise could be as high as 30 × 91% = 27%, a likelihood that is too dangerous to live with, as we noted. While this represents a worst-case scenario, it is not improbable.
The difference between open air fish markets in the states and China is night and day. I came across the wet market while waiting for a train to take me from Hankou (one of the three smaller cities merged into the current Wuhan) to Beijing. I had to power through it as partway through the place the overpowering scent caused me to get nauseous. I smelled like the market as I got on the train too. Felt bad for the people sitting around me because my excessive body spray use wasn’t able to completely conceal the scent from the market. So I ended up smelling gross in two different ways.
Keeed raised perfectly valid and uncontroversial questions about how the effect of money on science could distort scientific opinions, and your response is to try to shut down debate. Why?
Covid-19 probably came to people through an animal, and likely started spreading no more than a month or two before it was noticed in December of 2019, a World Health Organization draft report finds.
The least likely source: a laboratory leak, the WHO’s joint international team concluded.
I confess to not being a biologist and to also thinking that the lab theory is certainly possible.
However, if we’re ruling out (or at least making very very very unlikely) that it was engineered to be human infecting in the lab, then what happened is that, in a chance encounter between a human and a non-human infecting coronavirus, the virus mutated and was then able to infect a human.
Given that there have to be some safety protocols in the lab and not that many people there, whereas outside there are lots of animals, people and not many safety protocols, isn’t it a pretty conservative conclusion that there are indeed hundreds of times (at least) more interactions between humans and non-human coronaviruses outside the lab than in?
