Why do you think there is a virology lab looking at zoonotic diseases in Wuhan? Is it not likely that a high prevalence of zoonotic disease there, historically, has led to specific interest? Why is the Durham county hospital causing all this coal miners black lung disease!
Why does the Liverpool school of tropical hygiene and medicine cause this huge spike in non indigenous malaria!
Seriously: the wuhan virology lab is there, because the problem is there.
