In order to know the origin of SARS-CoV-2, we recently published an article about a letter to the director of the WHO from 32 scientists who expressed the need, on the part of the international community, to know about it.
They showed that the data available on the virus had sufficient basis to carry out a study on the origin of the virus without the support of the Chinese government, which refuses any independent study in its country.
This letter called on the WHO and the scientific community to an immediate investigation with the existing data. The scientific community is unanimous in considering that it is essential to know the origins of the virus to progress in research on the virus and to anticipate possible new pandemics.
SARS-CoV-2 leak gains strength
In the previous epidemics, SARS-CoV-1 and MERS in 2012, it was proven in a few months that these viruses came from animals, which incubated them and transmitted them to humans. In the case of SARS-CoV-2, 80 species were investigated with negative results. As is known, one of the mistakes of the UN was to pronounce categorically from the beginning in favor of the zootechnical origin and defining as very unlikely that the origin of the pandemic was in a leak from the Wuhan laboratory, which has hindered progress in the clarification of the origin of the virus and has strengthened the secrecy of the rulers of the Chinese Communist Party.
A recent article in the American newspaper Wall Street Journal – WSJ of October 5, 2021, with the title “Science Closes In on Covid’s Origins“, makes a review of all the studies that are being carried out and the results they are obtaining. It seems that the aforementioned manifesto of the 32 scientists took effect and even the WHO is studying more seriously the possibility that the origin of COVID 19 could be due to a leak of the virus from the laboratory.
A team of American scientists determined that the original SARS-CoV-2 pathogen was 99.5% optimized for human infection, which is a strong confirmation of the lab-leak hypothesis. SARS-CoV-2 contains a key mutation: the “furin cleavage site,” or FCS. This mutation could have been inserted by humans or by nature.
In the latter case, the process is called recombination, and it involves a virus exchanging parts of itself with another closely related virus when both infect the same cell.
In the National Institutes of Health (NIH) database, with more than 1,200 viruses, none of them shows the mutation detected in SARS Cov-2, an indication that the authors of the aforementioned article interpret as a possible consequence of human manipulation of the virus in the laboratory.
Adding to the already obstructive attitude of the Chinese authorities is a recent letter from the evolutionary biologist Jesse Bloom of the Fred Hutchinson Cancer Research Center, published by Science, which states that Chinese researchers sequenced viruses from some of the first patients in Wuhan and sent the sequences to the NIH and then this genetic information was removed “to obscure its existence.”
This statement was followed by a request from a senator to the NIH to explain why they agreed on the request of the Chinese authorities to “purge” its database. Ian Lipkin, a microbiologist at Columbia University’s Mailman School of Public Health stated that “There may have been active suppression of epidemiological and sequence data needed to trace its origins” (see HERE).
SARS-CoV-2 leak gains traction, WSJ’s article says is not necessary more studies
The WSJ article ends with a reflection that we find interesting and we transcribe: “Let China keep its firewall of secrecy; a suspect who refuses to testify can still be convicted. We have an eyewitness, a whistleblower who escaped from Wuhan and carried details of the pandemic’s origin that the Chinese Communist Party can’t hide. The whistleblower’s name is SARS-CoV-2.”
