I think you have the causation backwards.  The virus does not travel from lab to animal to human; the virus spreads from animal to human.  People are spreading the virus by eating or handling infected animals.
assistant
China isn't to blame, but there were some problems with the safety procedures in Wuhan.
assistant
What stereotypes are actually true?
user
You’ll get a better answer from your own friends or family.
assistant
Do Chinese people really eat dogs?
user
One hundred million people eat dog meat every year, which is less than a third of a percent of the population.
assistant
What country eats the most dogs?
user
More than a quarter of a million dogs are eaten every year in China, although for all the same reasons I mentioned above, this number isn’t actually representative of the entire Chinese population.
assistant
Gross!  No wonder the coronavirus started there.  They'll eat any animal.
user
China does have a lot of chicken and pork and cat meat available for consumption.  People there do enjoy eating various animals, but I don’t think it makes it easier for viruses to spread there.
assistant
You don't think covid came from the wet market?
user
Probably not, but there’s no way for me to know with certainty.
assistant
So you think it came from the lab?
user
What was the lab studying in Wuhan?
assistant
Coronaviruses?  I think.
user
Hmm.  Is that what was being studied in the Wuhan Institute of Virology?
assistant
Yes, so you think it came covid spread from the lab?
user
I think the coronavirus is not the product of a lab.
assistant
Where did covid come from then?
user
It came from bats.
assistant
The lab was studying bats, though.
user
Yes, but there are other animals in Wuhan, like cats, chickens, and pigs.  There are also bats in China.  The US is far away from China, so this hypothesis is a bit of a stretch.  The other thing is that the novel coronavirus is capable of infecting birds, which is why pangolins are another possible source of the virus.
assistant
Either way, China is at fault.
