One picture understands the latest situation of the Shanghai epidemic situation

A total of 10 Omikon mutations appeared in China in two weeks

The greater the virus spread from BA.1 to BA.5, the more powerful the virus is?

The new crown pneumonia's epidemic is still spreading globally, and many people worry that the new coronal virus family is "new" again -BA.4 and BA.5 of Omikon mutations are becoming the world's major popular strains. Recently, an epidemic occurred in some places in my country. Through the sequencing of the virus genes of the infected person, the BA.4 and BA.5 mutant strains from overseas were found.

What is the propagation and pathogenicity of new mutant strains including BA.4 and BA.5? Is the existing new coronal virus vaccine effective? Can my country's current prevention and control measures respond? Gao Xiaodong, a member of the National Health and Health Commission medical institution infection and control expert committee, and deputy director of the infection management department affiliated by Fudan University, said in an interview with reporters: In the face of the continuous mutation of the virus Drop a light heart. The existing prevention and control methods are still effective, and traditional protection methods such as wearing masks must be implemented.

R0 value to the new coronary virus transmission coefficient R0

Have the right understanding

According to the data, since December 2021, the variants of the new coronary virus have been rapidly popular and have been rapidly mutated worldwide. Since the early detection of Omikon B.1.1.529, BA.1, BA.2, sequencing a few days ago is again sequencing again. Two new Asian series -BA.4 and BA.5 were discovered, and it was quickly popular in many countries.

So, from BA.1, BA.2 to BA.4, BA.5, is the larger number and the better the communication power? Experts told reporters that BA.5 has more mutations than BA.1, but the size of the numbers and the infectious power of the virus cannot be completely divided, and further research must be confirmed. "From the perspective of existing evidence, the spread of BA.5 is the strongest. If it is measured with the basic reproduction of the infectious disease (R0) to measure the infectiousness, when people do not obtain immunity, the new crown ancestor strains that have been spread in the early stage The R0 value is about 3.3, the R0 value of the deerta mutation strain is about 5.1, the R0 value of Omikon BA.1 is about 9.5, the R0 value of Omikon BA.2 is about 13.3, and BA.4/5 The R0 value may reach 18.6, "Gao Xiaodong told reporters. Dong Xiaoping, chief expert of the China Centers for Disease Control and Prevention, said in an interview with the media recently that compared with the previous mutant strains, the spread of BA.4 and BA.5 mutant strains has increased significantly. The specific performance includes: first, the incubation period is significantly shortened, that is, the infected person can be positive in a short period of time, and the ability to spread viruses more strongly; second, research in Japan, South Africa and other countries and regions show that there is no in the case of no. In the case of interference or few public health measures, its transmission coefficient R0 value has reached 18, which has a high speed of communication. In some European countries and the United States, the BA.5 mutant strain has replaced other Omikon mutant branches, becoming an advantageous strain.

Gao Xiaodong emphasized a key detail to reporters, that is, the R0 value of BA.4/5 may reach 18.6. The premise is "when people do not obtain immunity", "immunity" here can be understood as "immune capacity "Including not wearing masks, no protection, no social distance, no inoculation of new crown vaccines, etc. In other words, when people do not do any protection, the R0 value of BA.4/5 may reach 18.6. "At present, this situation is unlikely in our real life, because most people wear masks and pay attention to protection. This also reminds us to adhere to the importance and necessity of traditional protection and vaccination." Gao Xiaodong Say.

In essence, it is still the mutant strain of Omikon

Existing prevention and control methods are still effective

So, will the BA.5 mutant strain be more harmful to the body? Gao Xiaodong said that from the current observation, compared with other mutant strains in Omikon, the pathogenicity of BA.4 and BA.5 mutant strains has not significantly increased and weakened. However, if the BA.4 and BA.5 mutant strains have large -scale infections, it is still fatal for the elderly with basic diseases. Therefore, on the basis of the "three -piece set" of the original epidemic prevention, it is advocated that people actively implement the "new epidemic prevention three -piece set" -regular measurement of acid, vaccination of new crown vaccines, and active scanning codes.

"Although BA.4 and BA.5 are the branches of the mutant strains of Omikon, they are essentially the mutant strains of Omikon. From the perspective of communication, it is still mainly droplet transmission. Therefore The method of blocking droplets such as non -gathering is still very effective and important protective means. In addition, from our previous round of battle against the virus, the new crown vaccination is vaccinated against infection, especially anti -severe and critical dangerous, and critical illnesses. In terms of severe illness and even death, it is effective, so it is still encouraged to complete the vaccination of the new crown virus vaccination and give himself a layer of protection. "Gao Xiaodong said.
