On the afternoon of September 8, the joint prevention and control mechanism of the State Council held a press conference to introduce the scientific and accurate epidemic prevention and control situation and answer questions from the

Dong Xiaoping, chief expert of virology at the Chinese Center for Disease Control and Prevention, introduced that new branches of virus mutation evolution continue to appear around the world, such as BF.

the Aomi Kerong variant strain.
Mutations in the genome of RNA viruses are a very common natural phenomenon, and viruses have some mutations in the process of
replicating in infected humans, and these mutations are often random.
The new coronavirus is an RNA virus, and its genome is composed of nearly 30,000 nucleotides, and it is natural that one to several nucleotides may mutate during each replication process
.
On the other hand, the use of vaccines on a global scale and the formation of an immune barrier in a large number of naturally infected people in a short period of time will also accelerate the mutation of the new crown virus

For the mutation of the new crown virus, more attention is paid to the impact on the ability to spread, pathogenesis and immune escape, and not every so-called evolutionary branch or mutation will obviously affect the change of the above three capabilities, so the timely monitoring of virus mutation is very critical and very important for timely adjustment of prevention and control strategies and the development of
