　　Recently, the overall situation of China's new crown epidemic prevention and control is improving, and it has steadily entered the normalized prevention and control stage of "Class B and B Control".

For more than three years, China has always insisted on optimizing and adjusting prevention and control policies and measures according to the time and situation, effectively coordinating epidemic prevention and control with economic and social development, effectively protecting the lives and health of the people, and achieving major decisive victories in epidemic prevention and control.

On the 23rd, the Joint Prevention and Control Mechanism of the State Council held a press conference to explain in detail the three key points of the current prevention and control of the new crown epidemic in China.

　　Withstood the test of the impact of this round of epidemic

　　The Standing Committee of the Political Bureau of the CPC Central Committee held a meeting on February 16.

The meeting pointed out that China "has achieved a major and decisive victory in the prevention and control of the epidemic, creating a miracle in the history of human civilization that a country with a large population successfully emerged from the pandemic."

　　At the press conference on the 23rd, when talking about relevant content, Liang Wannian, head of the expert group of the National Health Commission’s Epidemic Response and Disposal Work Leading Group, said that from the perspective of public health, the epidemic intensity of a disease epidemic can be divided into four categories: category.

Among them, the strongest intensity is the pandemic, that is, the emergence of transnational and transcontinental transmission.

　　Liang Wannian said that the new crown epidemic is still a public health emergency of international concern. From a global perspective, the state of the pandemic still exists, and the hazards of the disease still exist.

However, China's overall prevention and control of the new crown epidemic has achieved a major and decisive victory. As a populous country, it has successfully emerged from the pandemic and "created a model."

　　A reporter asked at the press conference: "How do you understand 'decisive victory'? Does this mean that the current round of the epidemic is over?" Liang Wannian pointed out that for China, this means that it has withstood the epidemic The impact and test of the rounds of epidemics have established a relatively good immune barrier for the population.

　　There are still cases of new crown infection in various places

　　At present, the global epidemic is still prevalent, and the virus is still mutating.

Recently, the epidemic situation in various parts of China has been sporadic and sporadic, and some elementary school students have been found to be infected with the new crown virus for the first time in some places.

　　Chang Zhaorui, a researcher at the Communication and Prevention Department of the Chinese Center for Disease Control and Prevention, pointed out that there are still cases of new coronavirus infection in various places, and people who have not been infected before may still be infected.

Schools are crowded places with high density. Once a source of infection is introduced, there is a risk of infection for uninfected people.

"However, because the overall immunity level of our population is relatively high at present, the risk of a large-scale cluster epidemic is low."

　　How to continue to improve the epidemic monitoring system and information reporting system has also attracted much attention.

According to Yang Feng, director of the Surveillance and Early Warning Department of the National Bureau of Disease Control and Prevention, China has initially formed a multi-channel monitoring system that takes into account normal and emergency, entry and local, urban and rural, general population and key populations.

"In the prevention and control of the new coronavirus infection after optimizing and adjusting the prevention and control measures, scientifically studied and judged the epidemic trend and the infection level of the population, dynamically grasped and evaluated the mutation of the new coronavirus, and issued an early warning signal in time."

　　Chang Zhaorui also said that at present, in the detection of new coronavirus mutant strains in China, if the first reported (including imported and local) and international epidemic strains of focus are found, infection case investigations, core close investigations and risk research and judgments will be carried out. .

Once a new mutant strain with enhanced transmissibility, pathogenicity or virulence is discovered, measures will be taken in accordance with relevant plans in a timely manner.

　　A new round of large-scale epidemics is less likely

　　Recently, the Chinese Center for Disease Control and Prevention released the national epidemic situation of new coronavirus infection, showing that 1 case of XBB.1.5 and 1 case of BQ.1 were newly added mutant strains.

Is this likely to trigger a new round of infection peaks?

　　Chang Zhaorui said that since the implementation of the "Class B and B Control" of new crown virus infection on January 8 this year, China has discovered 7 local-related XBB.1.5 cases caused by imported cases through monitoring, and they are core close contacts.

After detailed epidemiological investigation, health testing of relevant close contacts and expert judgment, no further cases were found.

　　"Although XBB.1.5 has a strong transmissibility, current data show that the symptoms of individuals infected with XBB.1.5 are similar to those of other Omicron strains, and no increase in its pathogenicity has been found."

　　The expert also pointed out that China has just experienced a pandemic, and the neutralizing antibodies remaining in the population will provide immune protection in the short term.

According to expert research and analysis, it is less likely to trigger a new round of large-scale epidemics in the near future.
