China Disease Control: After the epidemic occurs, these three conditions are met, and there is no need to perform all the nucleic acids

On July 21, at the press conference of the State Council ’s joint control mechanism, Mi Feng, spokesman for the National Health and Health Commission and deputy director of the Propaganda Department, introduced that at present, the global epidemic is still at a high level, and the number of newly added diagnosis cases has exceeded 100 times many times. Thousands of cases, Omikon BA.5 Asian branches have become the major popular plants in the world, and the pressure on foreign defense input is increasing.

Recently, the local clustering epidemic has been reported in many places in the country. There are multiple transmission chains, and the situation of the epidemic prevention and control is severe and complicated. The comprehensive group of the State Council ’s joint defense and control mechanism has sent a working group to relevant provinces to guide the localities to control the epidemic at the shortest time and minimum cost.

We must adhere to "external prevention input, internal prevention and rebound", adhere to the "dynamic clearance", strictly implement the ninth edition prevention and control plan and the "nine inaccurate" requirements, and do not relax. To deal with quickly, comprehensively improve the efficiency of the entire chain, strive for science and precision, and strive to facilitate the masses.

Omikon BA.4 and BA.5

Indeed, it shows the phenomenon of enhancement of communication capabilities

Dong Xiaoping, chief expert of the China Centers for Disease Control and Prevention, introduced that Omikon BA.4 and BA.5 have spread ability. If compared with other evolutionary branches of Omikon, it does show the phenomenon of increasing communication capabilities.

Dong Xiaoping introduced that the spread of BA.4 and BA.5 Asia branches has increased slightly compared to other Omikon mutant strains, which are mainly manifested as:

1. Studies in some international countries have found a higher regeneration index of the virus (R0);

2. Some countries and regions BA.4 and BA.5 Asian branches have become popular strains;

3. In the past 5 weeks, the number of infections in Europe and North America has increased.

The pathogenic force of BA.4 and BA.5 sub -branches is generally similar to other Omikon mutant strains, but in the elderly, the rapid dissemination has occurred. The recent hospitalization rate and ICU in 12 countries in Europe are used. The rate has increased. Research on epidemiological mathematics models show that the infection rate and mortality rate caused by branches of BA.4 and BA.5 Asia will increase.

Although the spread of BA.4 and BA.5 Asian branches has increased, it still belongs to Omikon mutant strains. There is no evidence that the existing NPI (non -drug intervention) measures will fail. In other words, my country's existing prevention and control measures can still be effectively cope.

Omikon is unlikely to be the last mutant strain

Dong Xiaoping introduced that virus mutations, especially the variation of RNA virus is the basic characteristics of virus survival. When the virus host (crowd) generates a certain group of group immunity to a certain group of strains through natural infection, vaccination, etc. It is one of the reasons for many viral infectious diseases to breed with partial breakthrough immune barrier to reproduce. The new crown virus is indeed a "clever" and "cunning" virus. In just two and a half years, multiple mutant strains have emerged, forming a number of popular peaks.

Regarding the mutation of the new coronal virus, most scholars believe that it will exist for a long time. The Omikon mutant strains should not be the last mutant strain. The influence will be our long -term focus.

Dong Xiaoping introduced that domestic and foreign experts believe that the current vaccination of vaccines is still valid. Vaccination for the elderly and people with basic diseases, especially for inocus, is still the most effective prevention measure.

County (city, district, flag) without epidemic situation)

Implement normalization prevention and control measures in the whole region

Wang Liping, a researcher at the Defense Office of the China Centers for Disease Control and Prevention, introduced that in the past prevention and control work, a high, middle and low risk areas need to be defined in the place where there is a local epidemic, which is convenient for other regions to investigate the risk personnel who may flow in time. The controlled area and prevention zone of the seal control area are convenient for rapid disposal of local epidemic dissemination. In order to further simplify the actual operation of the epidemic prevention and control and solve some problems exposed in the strokes of the two sets of risk areas, the ninth edition of the prevention and control scheme integrates the two sets of risk areas. Using the concept of high, middle and low risk areas to form a new risk area delineation and control scheme.

The division of high, middle and low risk areas is divided into counties (cities, districts, flags) that occurred in the epidemic. The county (city, district, flag), which does not occur, implements normalized prevention and control measures in the entire domain. For high -risk areas of high -risk areas, 7 -day centralized isolation medical observation is adopted in the place where the central risk zone overflowing cross -regional overflow adopting 7 Heavenly House medical observations. Low -risk areas who go out across areas do not need to take isolation control measures, but they are required to complete two nucleic acid detection within 3 days and do a good job of personal health monitoring.

Meet these conditions

No need to perform all kinds of nucleic acid

Wang Liping introduced that after the epidemic, if the epidemic survey, comprehensive risk research and judgment, meet the following conditions: clear sources of infection, clear transmission chain, and unprepared community transmission, there is no need to conduct a full -member nucleic acid test on the areas of the epidemic. Focus on risk -up risk -intersecting risk personnel to conduct nucleic acid testing.

Amend the prevention and control plan

Mainly based on these three considerations

He Qinghua, a first -level inspector of the National Health and Health Commission's CDC, introduced that in the ninth edition of the prevention and control plan, the first is to optimize the time limit and method of adjusting the isolation control and control of risk personnel. The second is to unify the standards for controlled control areas and high -risk areas, and the control measures are clarified. The third is to improve the requirements of epidemic monitoring, and the frequency of nucleic acid testing of the encrypted risk population clarifies the strategy of regional nucleic acid detection in different scenarios. These revisions are mainly based on 3 aspects:

The first is the needs of the epidemic prevention and control situation. The new coronary pneumonia epidemic is still continued to be popular worldwide, especially the frequency of local epidemic in the country has increased significantly since this year. The situation is more severe and complicated.

The second is the characteristics of virus variation. Omikon mutant strains have become the advantages of my country's overseas input and local epidemic. Omikon's mutant plant has a short incubation period, more virus transmission ability, faster transmission, and enhanced hiddenness, bringing new challenges to the prevention and control of the epidemic.

Third, based on the results of the early pilot work and the experience of the actual combat of the epidemic prevention and control, the comprehensive group of the State Council's joint prevention and control mechanism in the State Council was carried out in 7 entry cities including Dalian, Suzhou, Ningbo, Xiamen, Qingdao, Guangzhou, and Chengdu. The pilot work for the optimization of the new crown pneumonia epidemic prevention and control measures. At the same time, the practice of the practice and epidemic disposal experience of various places has been absorbed.
