In late 2019, personnel at the Wuhan Institute of Virology where research involving infecting human cells with Coronavirus was being done, became infected with Covid-19. This contagion quickly spread across the populous of Wuhan including staff and customers at the Wuhan wet markets. The Wuhan wet market zoonotic transfer theory gave the PRC cover to destroy evidence at the Wuhan Lab and obstruct any international investigation .
No other wet markets across China had animals with Coronavirus and no evidence of zoonotic transfer. Wuhan has the same wild animal supplier as many other cities wet markets but is the only city where a lab exists that was deliberately infecting human cells with Coronavirus.
It is highly probable that the Covid-19 virus came to the Wuhan wet market staff from the lab leak.
The PRC’s destruction of evidence was not limited to the Wuhan Market but also at the Wuhan virology institute.
To this day, physicians in Wuhan that treated patients when the outbreaks where occurring and were kept secret are forbidden to speak about the early days of Covid-19 in that city by punishment of incarceration including death.
