Scientists from the United States put forward a new version of the appearance of SARS-COV-2 coronavirus. They suggest that he could evolve from an infection found from a Chinese miner who has become infected in 2012. Reports about it The Telegraph.
As explained by the executive director of the American organization Bioscience Resource Project Jonathan Latem, viruses can pass many evolutionary stages in the body of one person.
What happened to miners?
In 2012, miners in Uhana got sick similar to the pneumonia of the disease after contacting the litter of volatile mice in one of the caves. After that, Wuhan scientists found in the same place the traces of the coronavirus of the bats of Ratg13, which is 96 percent similar to COVID-19. According to the theory of American scientists, an unknown virus evolved in light miners six months before the form of SARS-COV-2, the samples of which in 2019 fell outside the Wuhan laboratory as a result of leakage.
It is noteworthy that this theory was expressed last year. According to her, the place of appearance of a new coronavirus infection can be a Moodsian cave in China, because in 2012 it was discovered similar to SARS-COV-2 virus. Then six men aged from 30 to 60 were infected with severe respiratory infection after they cleaned the caves from the excrement of bats for subsequent production of copper. Three of them subsequently died due to illness.
The survey showed that they were infected with coronavirus, called RATG13. Samples of the virus were collected by the Wuhan Institute of Virology. Then the Indian researchers suggested that Ratg13 could be a close relative SARS-COV-2. However, scientists from France denied this point of view.
refutation
According to French scientists, people infected with RATG13 were observed symptoms that are very different from those that manifest themselves in patients with COVID-19. Studying medical reports of miners showed that, unlike patients with COVID-19, they coughed blood and mucus.
Computer tomography showed that the sick men did not have scarring 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.
Other opinions
The results of the French study were questioned by other scientists. Virologist from Warwick University in the UK Professor Lawrence Young stated that the theory of laboratory leaks “cannot be excluded”, and Professor David Livermore pointed out “some wonderful coincidences”, since the pandemic began in Uhana, which is far from the volatile mice caves in the south of China Where is the Institute of Virology, conducting molecular work with coronaviruses.
