There were 89 positives added in China!This mutant plant enters the host cell in 2 minutes ...

At 0-24 on September 3, 89 positive cases were added in Shenzhen. 79 cases were found out of the isolated observer. Four cases were found in the screening of key personnel, and 6 cases were found in community screening; 69 cases were diagnosed as confirmed cases of new coronary pneumonia, and 20 cases were diagnosed as asymptomatic infections of the new coronary virus.

On the 3rd, Shenzhen held an epidemic prevention and control press conference. Lin Hancheng, a second -level inspector of the Shenzhen Municipal Health and Health Commission, said that the risk of the existing epidemic in Shenzhen is large and continuously released, and the risk of social communication is still high.

Omikon BA.5 mutant plant can enter the host cell in 2 minutes

At the epidemic prevention and control conference, Lu Hongzhou, Dean of the Third People's Hospital of Shenzhen, introduced that since the end of 2021, Omikon BA.5 mutant strains have become the world's main popular mutated strains. Recently, Shenzhen has added local cases in Shenzhen. The infection is also mainly Omikon BA.5 mutant strains.

From the perspective of virus characteristics, the BA.5 mutant strain has stronger replication and dissemination capabilities than BA.2 mutant strains. Studies have also shown that the BA.5 mutant strain can enter the host cells in about 2 minutes, and present the index of the upper respiratory tract in about 20-30 minutes. Start detoxification and spread through droplets, gas solution and other methods.

The threat of the Omikon BA.5 mutation still has great threat to the elderly

Since the beginning of this year, there have been cases of Tianjin, Xi'an, Beijing, Beijing, Shanghai, Liaoning Dalian, Zhuhai, Guangdong, Sanya, Hainan, Chongqing and other places that have reported infection with Omikon BA.5 mutant strains and their evolutionary branch strains.

In terms of communication capabilities, Academician Zhang Boli previously stated that the mutant strain of Omikon BA.5 was considered the strongest strain at present. Studies have found that they have stronger immune escape ability and ability to repeat infection than predecessor.

In terms of pathological ability, the severity of the BA.5 infected person has not changed much compared with the early mutation strains of Omiko, but the threat to the elderly is still very large, especially the elderly who have not vaccinated the vaccine infection infection infection BA.5, the risk of severe illness and death is still high.

At present, multiple evolution branches of Omikon BA.5 mutant strains have been reported in China:

BA.5.1, BA.5.1.3, BA.5.2, BA.5.2.1 and BF.15. Among them, the BF.15 mutant strain is the sub -branch of BA.5.2.1, which is the first discovery of Shenzhen for the first time. Its hiddenness and communication ability are stronger.

Must be alert to Omikon BA.5 mutation strain to strengthen prevention

In the face of the Omikon BA.5 mutant strain with such communication capabilities, should we prevent?

Scientific norms wearing masks

Yuan Zhengan, a member of the expert group of the Shanghai Epidemic Prevention and Control Work Group, introduced that the spread of Omikon BA.5 mutant strains is mainly droplet transmission. Personal hygiene) and "five protection" (the mask should be worn, the social distance must be left, the cough and sneezing must be covered, the hands should be washed often as possible). One of the effective prevention and control measures.

Remind again that the way to wear a mask scientifically and standardized is that after wearing a mask, the two index finger presses on both sides of the nose, so that the nose clip is fitted with the facial skin, and the mask completely covers the nose and chin. It is also recommended to replace the mask every four hours to effectively use the mask's protection ability.

Vaccine vaccination still has a protective effect on BA.5

On July 23, at the press conference of the State Council's joint control mechanism, the deputy director of the National Health and Health Commission, the person in charge of the research and development of the research and development of the research and development group of the Scientific Research Research Group, and Zeng Yixin, an academician of the Chinese Academy of Sciences. The neutral ability of .5 was reduced, but the cellular immune generated by vaccine vaccination was relatively good for virus variation. The results of the real world also show that vaccination still has a good protective effect on pneumonia, severe and death caused by BA.5.
