[Southern January 12th] According to Russian media reports, Russian scientists have published the results of a study describing the condition of a patient who has 18 new mutations in the new coronavirus . This patient is a 47-year-old Russian woman with malignant lymphoma . She was infected with new coronary pneumonia during chemotherapy in April 2020. The test result showed that her new coronavirus infection was positive.
Russian scientists said, “We analyzed the gene of a lymphoma patient with new coronary pneumonia. This genome feature has 18 new mutations in more than four months.” The scientist pointed out that the patient Observed and conducted research from April 2020 to September 2020. During this period, she was examined several times and conducted a comparative study. The results showed that there are many new mutations of the new coronavirus, including the two mutations found in Danish mink. However, this woman has not been in contact with mink, and these mutations are "independently acquired", which shows that the mutant virus has greater uncertainty and may have been "independently mutated" without contact.
The patient was observed until mid-December 2020. During this period, she had been tested for new coronary pneumonia several times, and the test results showed that the new coronavirus has experienced "rapid evolution in the host." From April 10, 2020 to August 20, 2020, that is, within 132 days, 18 changes were observed, which was significantly higher than the average evolution rate of the new coronavirus. The results of this analysis were obtained by Somodin Seva, a scientist from the Skolkovo Institute of Science and Technology and an expert from the Russian Institute of Influenza. The
mutant virus has a large number of gene mutations in the gene sequence, which is worrying. When the new mutation of the new coronavirus first appeared in the UK, England's chief medical officer Chris Whitty said in a statement that after relevant research and model analysis, experts believed that the new mutant virus "can spread faster." However, even if the virus spreads faster, it does not mean that it is more pathogenic. In the eyes of the virus, reproduction and wider spread are the goals, not killing the host.
Earlier, Alexander Gunzburg, head of the Epidemiology and Microbiology Research Center, said that Russia may have a new mutation of the new coronavirus that is different from the United Kingdom, but it has not yet been formally identified. As of 11 o'clock on January 12, 2021, Russia has confirmed a total of 3,448,203 cases, a total of 62,804 deaths, and 22,934 new cases within 24 hours. In order to curb the spread of the epidemic, Russia has begun large-scale vaccination . This can inhibit the spread of the new coronavirus and prevent further spread of the virus.
