In the study, published in the science journal Nature, Shi said that her team recently re-tested samples taken from miners, and it has been proven that they are not infected with “SARS-Cove-2 ‘, Which is inconsistent with “Conspiracy theoriesSurrounding Shi, saying that her laboratory is the origin of the virus that causes Covid-19.
The Chinese scientist explained in detail how she and her team studied the bat corona virus, known as RaTG13, in 2012, denying that it was a source. Corona Virus Novelty.
According to the new results, the viruses that Shi and her team collected, whether from animals or humans, before the outbreak of Corona in Wuhan, central China, in late 2019, was not “SARS-Cove-2”.
Commenting on these theories, Xi said at the time that bats may be the primary host for “SARS-Cove-2”, without specifying the intermediate host between bats and humans.
And in the latest update in this regard from Shi, last week, the scientist said that her team collected 13 samples from four miners who contracted a mysterious respiratory disease after removing their feces. Bats In a copper mine in Yunnan Province in April 2012.
Shi explained that her team collected samples from various animals near and inside the aforementioned cave between 2012 and 2015, including bats, rats and mosquitoes, as the RaTG13 bat virus was found in one of the samples, and the genome sequence of this sample was deposited in a special database in 2016.
She accused of trying to cover up the similarity of RaTG13 with “SARS-Cove-2”, and that she came to the truth that they are the same virus, which the scientist denied, noting that the name is based on the number of samples, the species of bats, and the location from which they were taken.
“In 2020, we compared the SARS-Cove-2 sequence to our unpublished one,” Shi explained. Coronavirus Of the bat, and we found it shares a 96.2 percent identity with RaTG13. “
And she continued: “The difference of 3.8 percent in the genome means that the bat coronavirus took decades to mutate into SARS-Cove-2.”
And she was World Health OrganizationLast July, it was announced that two experts had arrived in China, in order to lay the groundwork for a larger mission to investigate the assets of The COVID-19 pandemic.
Scientists believe that the virus may have originated in bats and was then transmitted through another mammal such as A civet cat or Scaly anteater Before moving to humans in a fresh food market in the city ووهان Central China late last year.
More than 120 countries called for an investigation into the origin of the virus in May, while China insisted that the World Health Organization lead the investigation and wait until the epidemic was brought under control.
The last mission of the World Health Organization (WHO) related to the Coronavirus in China was in February, and at that time the team leader, Canadian doctor Bruce Aylward, praised Chinas efforts regarding containing the outbreak and exchanging information, and Canadian and American officials criticized him, saying that he was very lenient with China.
The complaints included that China delayed the release of the genetic map of the virus for more than a week after three different government laboratories completely decrypted the information.
