Zhongxin Jingwei, July 21st. On the afternoon of the 21st, the State Council's joint defense and control mechanism held a press conference on the relevant situation of the prevention and control of the epidemic. Dong Xiaoping, chief expert of the China Centers for Disease Control and Prevention, said at the press conference that although the spread of BA.4 and BA.5 Asia branches has increased, my country's existing prevention and control measures can still be effectively cope.

Some media questions have a lot of sayings about the branches of BA.4 and BA.5 Asian for Omikon's mutation. What is its transmission and pathogenic force? Can our existing prevention and control measures effectively cope with such mutant viruses?

Dong Xiaoping responded that the spread of the BA.4 and BA.5 sub -sub -sub -sub -sub -sub -Asian branch was slightly increased compared to other Omikon mutant strains, mainly manifested as:

1. Studies in some international countries have found a higher regeneration index of the virus (R0);

2. Some countries and regions BA.4 and BA.5 Asian branches have become popular strains;

3. In the past 5 weeks, the number of infections in Europe and North America has increased.

Dong Xiaoping revealed that the pathogenic force of BA.4 and BA.5 Asia branches is generally similar to other Omikon mutant strains, but in the elderly, the rapid transmission has appeared. Both the ICU usage rate has increased. Research on epidemiological mathematics models show that the infection rate and mortality rate caused by branches of BA.4 and BA.5 Asia will increase.

Dong Xiaoping said that although the spread of BA.4 and BA.5 Asia branches has increased, it still belongs to the Omikon mutant strains. There is no evidence that the existing NPI (non -drug intervention) measures will fail. In other words, my country's existing prevention and control measures can still be effectively cope.
