And the current city risk zone information

Some netizens asked:

Why do you do so much

Are they associated with 148 Lanxi Road, Putuo District?

Shanghai release response:

Discovered by epidemiological investigation

Yesterday, these are in isolation control

The positive infected person found through routine inspection

Both are listed as high -risk areas

Related epidemic situation on No. 148 Lanxi Road, Putuo District

Some netizens asked:

Isn't it a BA.5 strain?

Shanghai release response:

up to now

Completed virus gene sequencing results show

No BA.5 mutant strain was found

Both BA2.2

Citizens will worry about BA.5 strains

It is because of Xi'an and Beijing Xinfa epidemic situation

Virus gene sequencing infected by the infected person has pointed one after another

Omikon BA.5.2 branch

What are the characteristics of this new mainstream strain in the world?

The spread of BA.5 mutant strains is 6 times the original strain

In May 2022, South African researchers were published in a research article on MEDRXIV that from the basic infection (R0) data from the primitive virus strains of the new crown virus to its various mutant strains, each generation of new mutant strains The dissemination ability will be enhanced compared to the previous generation, and the virus is constantly evolving.

in:

The R0 of the original strain SARS-COV-2 is 3.3;

Delta's R0 is 5.1;

The R0 of Omicron BA.1 is 9.5;

The R0 of Omicron BA.2 is 13.3;

Muting plants BA.4/5 are more spread than BA.2, and its R0 is 18.6.

The R0 value of the mutant BA.4/5 is already 6 times that of the original strain (SARS-COV-2), exceeding the measles. And measles are one of the most contagious viruses that have so far.

Expert: BA.5 variable plant has strong spread and weak pathogenicity

On July 5th, Zhang Yi, director of the Prevention and Control Institute of the Shaanxi Provincial Disease Control and Prevention Center, said in an interview with the Western Network · Shaanxi headline that Omikon BA.5.2 mutant strain was stronger than the previous popular BA2.2 communication capacity, and spreading Fast speed and stronger immune escape ability.

"At present, the Xi'an epidemic situation is not clear, but this time the government responds very quickly. It has implemented strong control measures last night. The latent period of the virus can generally appear in 1-2 days." Xi'an Jiaotong University First Hospital infection He Yingli, deputy director of the section, told the Health Times reporter on July 6 that if social control control for a week, it can largely avoid potential hidden communication in the early stage, and should be controlled soon. He Yingli said that Omikon BA.5.2 mutant strains have been popular in many countries and regions for a while. From the perspective of foreign data, the spread of BA.5.2 variable strains is relatively strong, but the pathogenic rate is with the previous BA. 2 variation strains are equivalent, and it has not further extended its positive time, but it will be more heavy for some special patients, such as the elderly may have a longer respiratory symptoms.

"The pathogenicity of Omikon's genealogy is significantly reduced, and the lesions of the diseased parts are different." He Yingli said that Delta's strain mainly caused the lesions of the lungs, but Omikon caused by Omikon Ronglon caused The lesions are mainly in the bronchus and do not reach deeper, so the pathogenic ability will weaken, but because it appears in the large bronchial, it is more likely to discharge the virus, so its spread is stronger.

BA.5 puts forward higher requirements for epidemic prevention and control work

The newly released new type of coronary virus pneumonia prevention and control scheme (ninth edition) requires prevention and control measures to be more accurate and scientific, and achieve the best prevention and control effect with the minimum prevention and control cost. Requirements.

"The enhancement of virus immunization and escape ability has increased the difficulty of traceability and challenges to the prevention and control of the epidemic." He Yingli said, but the government responded rapidly this time, which greatly reduced the potential spread risk, and and offered. After having an emergency plan, you can get involved in advance once there are signs.

He Yingli said, "According to my country's epidemic prevention guidelines and the latest version of the new crown diagnosis and treatment guide, coupled with the effectiveness of the vaccine, as long as it can cut off the transmission of the epidemic in time, it can still play a good effect on blocking spread, epidemic prevention and control, . So whether it will cause large -scale communication in China, I think it is more optimistic. "
