MOSCOW, July 19 – RIA Novosti. Chinese scientists have established that the origin of the coronavirus can only be natural, the virus could not appear artificially – in the laboratory, according to an article published in the scientific journal Science China Life Sciences. Earlier, as reported by the Associated Press, the head of the World Health Organization Tedros Adhanom Ghebreyesus did not ruled out the possibility of an artificial origin of the coronavirus. More than 20 Chinese scientists and a British researcher working in the PRC conducted their scientific research and came to the conclusion that the coronavirus is of natural origin. They used the theory of evolution and related ideas as evidence, and they note that the SARS-CoV-2 virus has adapted very well to the human population compared to the 2003 SARS-CoV sample. This level of adaptability appears to have evolved over a long period, experts write. Prior to the COVID-19 outbreak, the virus appears to have undergone some form of evolution in the human population, leading to this degree of adaptability, but it is not yet clear exactly how this happened. “SARS-CoV-2 could not develop in the large animal market. city ​​and even less likely in the laboratory. When discussing the origin of SARS-CoV-2, it is necessary to take into account a long process of adaptive shift, “the scientific article says. It also notes that claims about the” unnatural origin “of coronavirus are highly controversial. strains with traces of human interference were found … it would be more productive to focus on the natural processes associated with the origin of SARS-CoV-2, “the publication emphasizes. The WHO published the full version of the report of an international group of experts of the organization on a visit to Wuhan to identify the origin of the coronavirus in March , in which they called the leak of COVID-19 from the laboratory “extremely unlikely.” The report also says that the new type of coronavirus was most likely transmitted to humans from bats through another animal. Another version of the origin of COVID – direct transmission to humans from an animal – experts have added to the list of hypotheses “from possible to probable.” The WHO mission also called the “possible” version of the emergence of COVID through chilled food. The United States and 13 other countries issued a joint statement expressing concern about the findings of the WHO report from the visit of the group of international experts, and stressed the need for a “transparent and independent” investigation COVID-19 origin, Chinese Foreign Ministry spokesman Zhao Lijian, commenting on the US intention to publish a report on the origin of COVID-19, called it a political game and an attempt to shift the blame on others. According to him, the fact that the United States is trying to allow the intelligence services to draw scientific conclusions only suggests that Washington is not interested in the truth.

Founding biologist of Moderna argues that the coronavirus left the laboratory in Wuhan – Mundo

Biologist Derrick Rossi is one of the founders of Moderna, one of the pharmaceutical companies that managed to develop a vaccine against coronavirus, and in an interview with the Spanish newspaper Trade, the specialist seemed to have no doubts about the origin of the disease that for a year and a half has haunted the world. Derrick Rossi believes the coronavirus came out of a laboratory in Wuhan, China.

“We don’t have any evidence, but this virus is so different from bats that it seems unlikely to me that it appeared naturally. FThe point is that a laboratory in Wuhan was working on it and I’m convinced that it came out of there, that it escaped them. I don’t think it was on purpose, they were just studying it and there was an accident. China denies it, of course, but it is the most logical explanation,” says the biologist.

During the interview, Derrick was also asked about the effectiveness of vaccines in relation to immunization, which he says is “difficult to know”. “It may be that the vaccine immunizes us naturally and it is not necessary to take more vaccines, but there can also be mutations in the virus and we have to be vaccinated every year, such as the flu. In any case, we are increasingly prepared for this.” , ensures.

About the Delta variant of Covid-19, which is spreading in the world and which is of greatest concern, the biologist believes that vaccines can fight Covid-19. “Viruses are the most perfect evolutionary unit that exists. They know how to adapt to any inconvenience and we may be able to adapt to the vaccine. The advantage of messenger RNA technology is that we are able to adapt to the virus quickly, that’s why I’m optimistic.”

Asked if there will be more pandemics or not, Derrick also says, to Trade, that “although we quickly forget about other pandemics that have existed, I believe that this pandemic was something exceptional, although we have no doubt that there will be more viruses reaching humans and causing disease.

“I hope we are prepared for that. There will be technologies that we don’t know yet that will help us, he adds.

Origin of Corona: Scientist finds deleted sequences in the cloud

Scientist finds deleted coronavirus sequences in internet database

US President Biden finally wants to know where the virus came from

The global community has been stuck in a pandemic for over a year. But where does the virus come from? US President Joe Biden now wants to know exactly and sets a deadline for his secret services.

According to a media report, a US virologist came across gene sequences from previous coronavirus cases in a cloud on the Internet. Experts are now hoping to gain new knowledge about the origin of the virus.

Ein American virologist recovered originally deleted coronavirus sequences when analyzing files from a Google Cloud. The “New York Times” reports. The information could therefore help to find out when and how the SARS-CoV-2 virus could have jumped from a bat or other animal to humans.

According to the report, the researcher has reconstructed the sequences from data from more than 200 virus samples from previous Covid-19 cases from the Chinese province of Wuhan. For unexplained reasons, these disappeared from a scientific database about a year ago.

Sequences from the early stages of the pandemic are particularly helpful for scientists. The new analysis, which was released on Tuesday, according to the report, supports the assumption that earlier variants of the Sars-CoV-2 virus were already circulating in animal and seafood markets in Wuhan before the first known outbreaks in December 2019.

“The phylogenetic analysis of these sequences (…) suggests that the sequences from the Huanan market, which are the focus of the joint report by WHO and China, are not fully representative of the viruses in Wuhan at the beginning of the epidemic,” the scientist writes Jesse Bloom of the Fred Hutchinson Cancer Research Center in Seattle on the new data.

The World Health Organization (WHO) published a report in March, according to which transmission of the coronavirus from an intermediate host animal as a trigger of Covid-19 is considered likely. However, critics consider the report to be inadequate.

However, the analysis does not provide any information on whether the pathogen originates from a laboratory in Wuhan. Above all, the find raises the question of why the original sequences were deleted in the first place.

Why was data deleted?

As the newspaper reports, virologist Bloom wanted to investigate which genetic data about the virus have been published by research groups. He came across a study from March 2020. Part of this study was a table with information on 241 genetic sequences that had been collected by scientists from the University of Wuhan.

The table showed that the sequences were uploaded to an online database called the Sequence Read Archive, which is maintained by the US government’s National Library of Medicine. When Bloom searched the database for the sequences from Wuhan, however, not a single result could be found. After comparing it with other data, Bloom was finally able to find 13 of the deleted sequences in folders in the Google Cloud.

Bloom considers the deletion of the sequences suspicious. It “seems likely that the sequences were deleted to disguise their existence,” says the paper, which has not yet been scientifically verified. The National Library of Medicine, which maintains the archive, announced that the 13 sequences were removed last summer. “These SARS-CoV-2 sequences were submitted for publication in the SRA in March 2020 and subsequently withdrawn by the submitting researcher in June 2020,” said Renate Myles, a spokeswoman for the National Institutes of Health.

“Great piece of detective work”

In order to draw clear conclusions from the new data, further investigations are necessary, it said in the report. “This is definitely a great piece of detective work and is a significant advancement in understanding the origin of SARS-CoV-2,” said Michael Worobey, a biologist at the University of Arizona who was not involved in the study.

Other scientists, on the other hand, were more cautious about gaining knowledge. “I don’t really see how this suggests a cover-up,” said Stephen Goldstein, a virologist at the University of Utah. The original study listed the individual mutations that Wuhan researchers found in their tests.

Although the full sequences are no longer in the archive, the key information has been public for over a year, he said. They were only hidden in a format that is difficult for researchers to find.

Covid: China, Wuhan institute deserves Nobel Medicine, no accusations – Asia

China returns to defend the Wuhan Institute of Virology, always at the center of suspicions about the origin of Covid-19, noting that it deserves the Nobel Prize for Medicine instead of the continuous international accusations.
This was claimed by the spokesman of the Foreign Ministry Zhao Lijian, after the recent interview with the New York Times released by virology Shi Zhengli, in which the “Bat Woman” at the head of the laboratory spoke of speculations against the Wuhan center and the absence of responsibility.
“The first discovery of the genome sequence of the new coronavirus by Chinese scientists does not mean that Wuhan is the source of the new coronavirus, nor can it be inferred that the virus was produced by Chinese scientists,” Zhao said. On the contrary, “the Wuhan team should receive the Nobel Prize in Medicine for research on the new coronavirus rather than being blamed.”
