Gonzaga: Did Covid-19 come from a lab?

Ecoviews and issues

Is considering a genetic-manipulation origin for SARS-CoV-2 a conspiracy theory that must be censored? This is the burning question of a new scientific analysis of the structure of SARS-CoV-2 that came to be known as the Covid-19 pandemic. In said treatise, the course of addressing that issue, the authors arrived at substantive, undeniable evidence that SARS-CoV-2, popularly known as Covid-19 did not morph naturally.

The Chinese popularized theory— that the Wuhan’s Huanan Seafood Wholesale Market was the first source for animal–human viral transmission, some western scientists and collaborating media, is now totally discredited, yes, even by the Chinese Centers for Disease Control and Prevention.

That Covid-19 as a naturally-occurring outbreak has been based, largely on a single, but widely-cited scientific article early in its phenomenal spread—“The Proximal Origin of SAR-CoV-2”, written by noted Chinese virologist. Though presently, China is pushing “a new “multiple origin” theory based on alleged genetic differences observed in the virus taken from a small sample of Chinese Covid-19 patients and published in March and May," the validity and significance of those findings are already in dispute, according to analyst, Lawrence Sellin.

As he writes, “There remains no credible scientific evidence that the Covid-19 pandemic was naturally-occurring. The evidence to the contrary, that the coronavirus responsible, SARS-CoV-2, was man-made is now substantial.” As he cites, “The most conspicuous sign of genetic manipulation is the presence of a furin polybasic cleavage site in SARS-CoV-2, a structure that is not present in any of the coronaviruses so far identified as possible recent ancestors.”

“According to the new study, the furin site was created by a genetic, nucleotide insertion that coded for amino acids proline, arginine, arginine, alanine (PRRA). The two arginines are coded by nucleotide “codons,” consisting of a sequence of three nucleotides each, CGG-CGG.

The codon CGG is rare. Only 5 percent of arginines are coded by CGG in SARS-CoV-2 or its closest identified bat coronavirus relative, RaTG13 and it is the only instance of a double CGG-CGG codon.”

A significant finding point to this: such a modification may have given SARS-CoV-2 the ability to infect cells and organs otherwise insensitive to unaltered coronaviruses.

Furthermore, the authors suggest that SARS-CoV-2 is a chimer, an artificially-created virus consisting of a pangolin (scaly anteater) receptor protein “spliced” onto a bat coronavirus backbone.

As Sellin cited in his article, “Due to the gravity of SARS-CoV-2 impact on humanity, researchers have the responsibility to carry out a thorough analysis, beyond any personal research interests, of all possible causes for SARS-CoV-2 emergence. Unfortunately, theories that consider a possible artificial origin for SARS-CoV-2 are censored by international scientific journals as they seem to support conspiracy theories. Genetic manipulation of SARS-CoV-2 may have been carried out in any laboratory in the world with access to the backbone sequence and the necessary equipment. New technologies based on synthetic genetics platforms even allow the reconstruction of viruses based on their genomic sequence, without the need of a natural isolate.”

Either SARS-CoV-2, responsible for the Covid-19 pandemic, is the product of a highly improbable and still unknown sequence of naturally-occurring coincidences, or it is a laboratory creation. What is your take?
