A new branch appeared in Omikon, and Chinese disease control experts are closely paying attention to the trend

Recently, the gene sequencing results of the new crown pneumonia infection in some regions of the country show that the virus belongs to the BA.5.2 branch of Omikon's mutant plant, combined with epidemiological surveys, and the source of the initial consideration comes from overseas. Virus experts said that the propagation power and immune escape ability of the new branches of Omikon mutant strains have increased slightly, and the pressure on foreign prevention input in China has increased.

On July 6, Beijing performed gene sequencing 1 to 3 infected on the 5th. The results showed that the viruses belonged to the BA.5.2 branch of Omikon. On the 5th, a press conference on the prevention and control of the epidemic prevention and control of Xi'an City introduced this round of epidemic infection.

Wang Wenling, a researcher at the China Centers for Disease Control and Prevention, introduced that the analysis of global virus gene sharing data shows that BA.5 has recently increased rapidly. In May, BA.4 and BA.5 were detected for the first time from the input case. Recently, the number of BA.4 and BA.5 input found in input cases has gradually increased significantly.

According to reports, BA.4 and BA.5 have now become the main popular strains of South Africa, Portugal, Britain, Israel and other countries. France, the Netherlands, the United States and other countries also have increased BA.4 and BA.5 infected people. Some experts predict that this summer may face a new wave of popularity caused by BA.4 or BA.5.

The relevant person in charge of the National Health and Health Commission's Disease Control Bureau stated that it is closely paying close attention to the trend of the national BA.4 and BA.5, promptly follow up the research progress of global new mutant plants, evaluate and judge in a timely manner, and guide localities to implement the "new model" new models The requirements of the coronary virus pneumonia prevention and control plan (ninth edition), scientifically and precisely do a good job of preventing and controlling the epidemic of Omikon mutation.
