At this stage, why should my country continue to adhere to the general strategy of "foreign defense against imports, internal defense against rebound" and the general policy of "dynamic clearing"?

What are the characteristics of this round of epidemic?

What is the focus and difficulty of prevention and control?

In response to these problems, a CCTV reporter recently interviewed Liang Wannian, head of the expert group of the National Health Commission's Leading Group for Epidemic Response and Disposal.

  Liang Wannian pointed out that there are several reasons why my country should pay special attention to adhering to the general strategy of "foreign defense against imports and internal defense against rebound" and the general policy of "dynamic clearing".

First of all, the current new crown pneumonia epidemic is still in a pandemic period from a global perspective, and the epidemic is far from over. The new crown virus is still seriously endangering human health and life safety.

Data released by the National Health and Health Commission shows that in the past week, new confirmed cases of new coronary pneumonia worldwide have rebounded again, of which more than 40% are concentrated in my country's neighboring countries and regions, and the pressure of foreign defense imports continues to increase.

The local epidemic situation in my country is developing rapidly, and many provinces are facing a situation of epidemic prevention and control dominated by Omicron mutants in many places at the same time. The prevention and control situation is severe and complicated.

In addition, due to public misunderstandings such as the end of the pandemic, and the fact that my country has always had a good overall epidemic prevention effect, some local governments and the public will inevitably feel paralyzed and relaxed.

  Liang Wannian, head of the expert group of the National Health Commission's Epidemic Response Leading Group: We must adhere to the general strategy and general policy, which is to consolidate our hard-won prevention and control effectiveness. This is also what General Secretary Xi Jinping has repeatedly emphasized. Persistence is victory, because With more than two years of practice of this kind of prevention and control, we have formed a set of our prevention and control concepts, strategies and specific tactics, which have effectively protected the health and life safety of the people, and effectively balanced the economy. The relationship between social development and epidemic prevention and control, it can be said that China's achievements in this regard are hard-won and must be cherished. At this time, there must be no slack and paralysis.

  "Dynamic clearing" emphasizes precision and maximum benefit with minimum cost

  Liang Wannian said that adhering to the general policy of dynamic clearing, in addition to quickly discovering and dealing with the epidemic, it is also necessary to be "accurate" and use the minimum cost to achieve the maximum benefit.

  Liang Wannian, head of the expert group of the National Health Commission's Leading Group for Epidemic Response and Disposal: Then to achieve the greatest benefit with the smallest cost, it is necessary to accurately conduct flow adjustment, accurately divide the population under control, accurately treat and carry out some related interventions. Measures, this is the most difficult thing to do in "dynamic clearing", and it also requires the most effort to do it well.

Why be precise? It achieves two effective balances, balancing epidemic prevention and control with social and economic development, and balancing epidemic prevention and control with normal production and life.

  Liang Wannian said that dynamic clearing has two meanings. One is an ideal state. There are no patients in society, but the uniqueness of the new coronavirus determines that we cannot do it for the time being.

The second meaning of dynamic clearing is that once an epidemic occurs, it can be quickly identified and dealt with, the transmission chain can be cut off, and the society in general will gradually move towards dynamic clearing.

If we do not pursue dynamic clearing, social dissemination will continue to connect and form a large-scale rebound.

  Liang Wannian, head of the expert group of the National Health Commission's Leading Group for Epidemic Response and Disposal: Are we learning from the Western style of "laying down" or insisting on China's "dynamic clearing"? The general secretary has made a clear request. It should be executed without hesitation.

The history of the fight against the epidemic is a process of constantly improving and optimizing our measures and strategies. Our improvement and adjustment just reflect that China's anti-epidemic is a scientific and orderly anti-epidemic.

  Is the new crown equivalent to the big flu?

It's too early to tell

  At present, some members of the public and scholars have proposed that the new crown caused by the Omikron variant is equivalent to a large-scale flu. In response to such a statement, Liang Wannian, head of the expert group of the National Health Commission's Leading Group for Epidemic Response and Disposal, said that it is too early to draw this conclusion. .

  Liang Wannian, head of the expert group of the National Health Commission's Epidemic Response and Disposal Leading Group: It is important to note that we cannot regard the epidemic of this disease caused by the epidemic strain of Omicron as a large flu, which is still unknown so far. Early, because its transmissibility and harm to human health are higher than ordinary influenza, it may be that for a certain individual, the probability of becoming seriously ill or other conditions is decreasing.

But as a whole, it spreads rapidly, the infection rate is high in a short period of time, and the absolute number of infected people is large.

Then, on the other hand, among the infected people, the absolute number of severe cases and deaths will be high, so this kind of high is a great harm to a society, a region, and a country. Therefore, from It is very important how the individual's thinking moves to the group's thinking.

  Liang Wannian said that although the harm of the new coronavirus cannot be underestimated, it is gratifying that in the process of fighting against it, human beings are gradually mastering some effective weapons with the development of science and technology: such as vaccination and the acceleration of specific drugs Research and development, including traditional Chinese medicine, has also played an important role in the fight against COVID-19.

In addition, through more than two years of anti-epidemic practice in China, the people have formed a conscious participation in the anti-epidemic, the awareness and behavior of being the master of the anti-epidemic, and the gradual development of good health literacy. These are our hopes to overcome the epidemic.

  Omikron is a challenge to cut off the source of infection

  According to the information released by the National Health Commission yesterday, from March 1 to March 18, my country has reported more than 29,000 cases of new coronary pneumonia, affecting 28 provinces.

At present, the local clustered epidemics in my country are characterized by many points, wide areas and frequent occurrences. Liang Wannian introduced that this is due to the characteristics of the Omicron variant.

  Liang Wannian said that from the earliest emergence of the new crown pneumonia epidemic to today's Omicron variant, the spread of the new crown virus has been increasing rapidly.

Stealth is increasing.

From the transmission characteristics of Omicron, the most important thing is that it brings great challenges to the discovery and management of infection sources.

  Liang Wannian, head of the expert group of the National Health Commission's Epidemic Response and Disposal Leading Group: Because it has a high proportion of asymptomatic infections and a high proportion of mild symptoms, it spreads more concealed.

In addition, it is mainly transmitted through the respiratory tract, the transmission route is easy to achieve, and the population flow is gradually increasing.

It is easy to move from one group of people to another, and even from one region or even one country to another with the frequent increase of traffic.

  Liang Wannian said that it is a common situation facing the whole world. Compared with the epidemic situation in other countries in the world, my country's epidemic prevention and control measures have proved to be effective.

However, we must also deeply realize that my country has a vast territory, different medical and health conditions in different regions, coupled with the imbalance of vaccination among different groups of people, and the absolute number of elderly people.

In view of the strong transmission power of the Omicron variant, the core of how to implement the prevention and control of the epidemic more thoroughly, comprehensively and accurately is to cut off the transmission chain as soon as possible and block the transmission.

From the organizational level of epidemic prevention and control to the intensity and breadth of specific measures, it must be matched.

  my country's existing measures to effectively curb the rising trend of the epidemic

  Recently, many places have adopted measures such as working from home, prohibiting cross-border movement of people, and online teaching to curb the spread of the epidemic.

Liang Wannian believes that, unlike the "exponential" increase in foreign infections, my country's epidemic prevention and control measures have played a role, and the spread of the virus has been effectively curbed.

  Liang Wannian, head of the expert group of the National Health Commission's Leading Group for Epidemic Response and Disposal: From a global perspective, in many countries.

The epidemic situation is rising rapidly in a short period of time, and the momentum of this rise is not a slow rise, but a steep rise, or even an exponential rise in academic terms. We have experienced this period of time, although It is said that there have been sporadic cases and even local clustered outbreaks, but the overall upward trend is not exponential. This is precisely because we have taken a series of effective intervention measures to curb its upward trend, so we must be confident.

  Liang Wannian said that for the Omicron variant, the key is to achieve early detection, strengthen the monitoring of key populations, key places, and key institutions, and implement early detection measures.

  Liang Wannian, head of the expert group of the National Health and Health Commission's Leading Group for Epidemic Response and Disposal: Our professional institutions at all levels of government must know that once an epidemic occurs, it must be taken quickly. In a fast take action, you may quickly kill it. In the budding state, what we are afraid of is hesitation, and what we are afraid of is luck. The virus is in a contest with us, and he is in a race with us. We must use this spirit and attitude to control it.

  Antigen detection and nucleic acid detection should be complementary and synergistic

  The newly released ninth edition of the "New Coronary Pneumonia Diagnosis and Treatment Protocol" adds antigen detection as a supplement to nucleic acid detection.

It is understood that online and offline platforms in many places have started sales.

Liang Wannian introduced that the effective complementarity and synergy of antigen detection and nucleic acid detection according to their characteristics is conducive to improving the ability of "early detection" of epidemic prevention and control in my country.

  Liang Wannian, head of the expert group of the National Health Commission's Epidemic Response and Disposal Leading Group: In the past, we mainly used nucleic acid testing, mainly because the sensitivity and specificity of nucleic acid testing were relatively good, and the probability and accuracy of positive detection were higher than that of antigens. is to be precise.

But it also has shortcomings: it requires special facilities and professional personnel to do it, so it is difficult to execute, and it will consume a certain amount of time and energy.

Antigen detection just makes up for this deficiency or defect.

However, the disadvantage of antigen detection is its sensitivity and specificity, that is, the accuracy that our people often say, it is not as good as nucleic acid detection.

By organically combining these two and learning from each other's strengths, we can greatly improve the efficiency and probability of our discovery of infection sources and potential sources of infection.

  Liang Wannian emphasized that since the antigen test is performed by himself, once a positive test is found, it must be reviewed and confirmed by a nucleic acid test.

How to divide and define the application of antigen detection and nucleic acid detection should also be clarified and refined in the next step.
