Academician Zhang Boli: BA.5 new strains are the most known transmission strains at present

"BA.5 strains are not only the most known strains known as the most well -known transmission, but the latest research has found that it has a stronger immune escape ability and repeated infection capabilities than the previous generation. Portugal, Britain, Israel and many other countries are popular, and it is likely to set off a new round of epidemic peaks globally. my country is facing greater pressure on foreign defense input. "On July 7, Zhang Boli, an academician of the Chinese Academy of Engineering, told the people that the people of the Chinese Academy of Engineering told the people that the people of the Chinese Academy of Engineering told the people that the people of the Chinese Academy of Engineering told the people that the people of the Chinese Academy of Engineering told the people Daily Health Client reporter.

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.

Earlier, a press conference on the prevention and control of the epidemic prevention and control of Xi'an City introduced this round of epidemic infected viruses in the infection of the infected virus of Omikon. Combined with epidemiological surveys, the source of the initial consideration comes from overseas.

Academician Zhang Boli said, "Recently, a new epidemic occurred in Xi'an, which opened the most severe epidemic prevention measures after the Spring Festival this year. The virus that caused the Xi'an epidemic was the new variant of the new crown virus — the strain BA.5. The strongest propagation of the strains. The latest research results in South Africa show that the R0 value of the BA.5 strain is as high as 18.6, which is the strongest virus of the currently known propagation ability. Recently, the virus gene of the virus gene of the clustering epidemic in Beijing The sequencing results show that the same comes from BA.5, which means that the BA.5 strains have been introduced to our country and caused local dissemination. The new situation of this epidemic needs to be highly valued. "

Regarding the epidemic prevention measures of the new crown virus strain BA.5, Academician Zhang Boli made five suggestions in an interview with the People's Daily Health Client:

First, those who take Chinese medicine as early as possible to take Chinese medicine prevention should give full play to the availability advantages of traditional Chinese medicine in the prevention and control of new crown pneumonia.

In the process of preventing and controlling the new crown pneumonia, Chinese medicine plays a role in "helping to dispel evil". It is constantly changing. Traditional Chinese medicine does not directly target the virus. The virus, which protects the damage of the tissue organs, has given full play to the unique advantages of traditional Chinese medicine treatment, dialectical treatment, and multi -target intervention.

Make full use of traditional Chinese medicine prevention measures in the prevention and control of the new crown epidemic. For people who close contact and high -risk factors, they can use the advantages of "cure disease" in Chinese medicine and build the second line of defense against the new crown pneumonia. Important value provides the public with another layer of protection other than vaccines.

Second, it is recommended to popularize nucleic acid antigen detection to respond to the spread of new strains.

New mutant strains are infectious, and in some grass -roots areas that do not have the ability to detect nucleic acid, or those who face some relatively high risk of infection, use antigen detection. The results. You can make the early detection of the mark forward, saving a lot of time and manpower for subsequent precision prevention and control.

However, antigen detection cannot replace nucleic acid detection. When antigen detection is positive, nucleic acid detection must be performed and confirmed.

The third is to comprehensively improve the vaccine vaccination rate of the entire people, especially the elderly, especially the elderly.

Faced with the new situation of new strains, the vaccination rate of the elderly group is not high, and the people infected with relatively few people are relatively high -risk groups. BA.5 has a strong ability to break through infection. The effect of vaccination for the entire vaccine protection barrier has weakened, but it still has the effect of reducing severe illness and mortality.

The new crown virus vaccine has always been an important means of prevention and control of the epidemic, and has obvious effects in preventing severe illnesses and death. In the epidemic in Hong Kong and Shanghai, the importance of vaccination is reflected. It is hoped that the elderly, especially the elderly with basic diseases, actively vaccinate the new crown virus vaccine.

Fourth, strengthen the work of traceability.

With changes, in order to make fast -moving, and more strictly carry out traceability and flow, strive to trace the source faster and precise, ensure that the secret and secondary connection are not omitted, and the high -risk groups focus on control. Check out the chain of the epidemic as soon as possible, and find out early isolation and early treatment to block the epidemic.

Fifth, it is recommended that the people do not travel to the high -risk area.

We must block the loopholes and adhere to the strict measures of "external prevention input". In which aspects may have vulnerabilities, airport passenger flow and goods should be disposed of at home and abroad, and properly dispose of parcel emails from high -risk areas at home and abroad.

For ordinary people, we must strengthen the protection of epidemic protection and do their own protection. The summer vacation is the peak tourist season. It adheres to strict protection measures. In particular, it is recommended that people do not travel to the high -risk areas. Tourist attractions and airports need to be more vigilant.
