A group of French scientists has denied the theory about the emergence of COVID-19 in the Chinese cave of Modzyan and the assumptions about the leakage of the virus from the laboratory. This is stated in the preliminary results of the study announced in the journal compassacedirect.
Last year, a group of researchers published an article in which it suggested that the Moodsian cave in China could be a place for the emergence of a new coronavirus infection, because in 2012 it was discovered similar to SARS-COV-2 virus. Then six people got infected with severe respiratory infection after they cleaned the caves from the excrement of volatile mice for subsequent copper mining. The men were infected were between the ages of 30 and 60, three of them died due to the disease. The subsequent examination showed that they were infected with coronavirus, called RATG13. Virus samples were collected by the Wuhan Institute of Virology. Indian scientists offered that Ratg13 may be a close relative SARS-COV-2, but French colleagues argue the opposite.
According to the preliminary results of a new study, people infected with RATG13 have observed symptoms that are very different from those that manifest themselves in patients with COVID-19. The study of medical reports of miners has shown that, unlike patients with COVID-19, they coughed blood and mucus. Computer tomography showed that men did not have scars on the lungs, which were observed in many hospitalized with the current coronavirus. Scientists also wondered why doctors and people with whom Chinese miners were closely in close contact, did not get sick.
“should also be wondering why a virus who killed more than five million people and infected more than 200 million in 18 months, did not cause any diseases in seven years from 2012 to 2019,” scientists said.
French researchers said that the results of their scientific activities also refute the previous statements about leakage of the virus from the laboratory. “Refusal to the theory of the occurrence of the virus from the Moodsian mine leaves hypotheses about a laboratory leakage without any scientific support, which makes them unreasonable assumptions,” the study says.
In this case, the results of this study were questioned by other scientists. Virologist from Warwick University in the UK, Professor Lawrence Young told Sputnik News that the theory of laboratory leaks “cannot be excluded”, and Professor David Livermore, a microbiologist from the University of East England, said that, although he believes that the theory of laboratory leaks is unlikely for The origin of the virus, exist “some wonderful coincidences.” “The pandemic began in Uhana, which is far from the caves of bats in the south of China, where the Institute of Virology, which conducts molecular work with coronavirus,” said Livermore.
Previously, scientists estimated the role of three analyzing blood test indicators affecting the survival rate of patients with a severe COVID-19, and found that specific antibodies are a key survival factor in infecting coronavirus.
