Origin of Covid-19: the “oddities” noted at the P4 laboratory in Wuhan by two pioneer researchers

the essential Researchers who have looked into the coronavirus responsible for Covid – 19 have discovered that one of the reasons for being from the Wuhan P4 laboratory is to modify viruses to understand the crossing of barriers between species.

In 2005, the Chinese virologist Zhengli Shi reaches a worldwide scientific fame. As part of a co-discovery, she has just established that the SARS virus in all probability originates from bats. It then multiplies the expeditions in the caves where the animal nests, likely to contaminate other species and collects hundreds of infectious agents. “She has become the essential Bat Woman”, summarizes science journalist Brice Perrier.

In 2013, she became the first scientist “to isolate a living Sars-type coronavirus from a bat” but also to “establish that it could directly infect human cells without necessarily needing to pass through an intermediate animal host. Enough to increase the risk of a pandemic “, underlines Brice Perrier.

” Lethal infectious weapon “

A CNRS researcher based in Marseille, Etienne Decroly is also an expert in coronaviruses and the famous “spike” proteins, this key allowing them to enter human cells in order to multiply there. This will make him a pioneer in the hypothesis of a research accident at the origin of the pandemic.

Very quickly, he spotted a peculiarity in the Sars-Cov-2 genome which is indeed the only Sars type to have a “furin cleavage site”, that is to say better than a key, “A sort of fatal infectious weapon” presents Brice Perrier, a discovery that Etienne Decroly published with five colleagues in February 2020.

An astonishing “oblivion”.

These scientists then believe that this is a “natural evolution”. But here it is… They also soon discover that one of the raison d’être of the Wuhan Institute of Virology (WIV) led by Zhengli Shi is to modify viruses to understand the crossing of barriers between species. It was then that Bruno Canard, another researcher in the laboratory, put his finger on an astonishing “oversight”.

When the WIV publishes in Nature its description of Sars-Cov-2, compared to RaTG 13, his most famous cousin, on 13 February 2020, the famous “site of furin cleavage ”strangely does not appear there.

How and why do researchers of this level make such an omission? Unfortunately, the calendar kills these crucial questions: between the untimely declarations of Donald Trump and the perverse platform of the Lancet , this question is deprived of a calm and rigorous scientific debate. But it will nonetheless become a motivation for in-depth research for the Paris Group and the DRASTIC collective.
