According to the domestic media reported on November 29, for the new virus, The Secret Kejong mutation strain, China Health as the organization, The Chinese Center for Disease Control and Prevention experts, answered relevant questions, for the relevant discovery and epidemic of the Secret Kejong mutation strain, experts pointed out that on November 9, 2021, South Africa found the First Omni Kejong mutation from the new crown virus test, in just two weeks, the mutation became the absolute dominant mutation strain of the new crown disease record in Gauteng Province, South Africa, growing rapidly, November 26, The WHO defines it as the fifth "concerned variant", named the Greek letter Omicron (Omicron) variant, as of November 28, Faye Wong, Israel, the United Kingdom, Italy, Hong Kong, etc., have detected the import of this case, and other provinces and cities in China have not yet found the import of this variant.
According to experts, according to the current news of the coronavirus database GISALD, the number of mutation sites of the new coronavirus Mystery Kejong mutation strain is significantly more than that of the new coronavirus variant strain circulating in the past two years. Speculation could be for these three reasons:
(1) After your defective patient is infected with the new crown virus, a large number of mutations are transmitted in the body by chance
(2) Animals are infected with the new crown virus, and the transmission process of the virus in the animal population undergoes adaptive changes, and the mutation rate is higher than that of humans, and then it is transmitted to humans
Experts went on to say that at present, globally, in the morning, the systematic study data on the transmissibility, infectivity and immune escape ability of the Obi Kejong mutant strain, the Obi Kejong mutant strain also has the important amino acid mutation sites of the first four VOC variants, including mutation sites that enhance the replication ability of the cell affinity virus, and epidemiological and laboratory monitoring data show that the cases of Infection with the Obi Kejong mutant strain in South Africa have surged. However, experts said that China's "external anti-import, internal anti-rebound" prevention and control strategy, the Obi Kejong mutant strain is still effective, the Chinese Center for Disease Control and Prevention of the Virus Disease Institute, has been established for the Obi Kejong variant strain, specific nucleic acid detection methods, continue to target possible import cases, carry out virus genome monitoring, the above measures will be conducive to the timely discovery of possible imports into China's Mi mikron variant strain.
