The 9th edition of the prevention and control plan is reduced?China Disease Control: Optimize, not relaxing

July 21st

The State Council joint prevention joint control mechanism holds a press conference

Introduce the situation related to the prevention and control of the epidemic

Recently reporting local gathered epidemic in many places in the country

The situation of preventing and control is severe and complicated

The National Health Commission spokesman Mi Feng said at the press conference of the State Council ’s joint prevention and control mechanism on the 21st that at present, the global epidemic is still at a high level, and the number of new diagnosis cases has exceeded 1 million times. The sub -branches have become the major popular plants in the world, and the pressure on foreign defense input in China has continued to increase.

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.

Mi Feng said that we must adhere to the "external prevention input and internal defense rebound", adhere to the "dynamic clearing zero", strictly implement the ninth edition prevention and control plan and the "nine inaccurate" requirements, and do not relax. Prevention, early discovery, and fast disposal, comprehensively improve the efficiency of the entire chain, strive for science and precision, and strive to facilitate the masses.

The epidemic affects 78 cities in 21 provinces

7 provinces report more than 100 infected people

He Qinghua, a first -level inspector of the National Health and Health Commission's CDC, introduced that since July, the country's epidemic situation is generally in a low level of volatility. Recently, a few regional epidemic conditions have rebounded. The local epidemic in the daily report has increased. In the past week, the epidemic affected 78 cities in 21 provinces, of which more than 100 infected people reported in 7 provinces. The epidemic situation in Lanzhou, Guangxi, and Henan in Gansu is still in progress, and the risk of spreading society is greater.

On the 20th, 148+678 was added nationwide, distributed in these places:

At 0-24 o'clock on July 20, 31 provinces (autonomous regions, municipalities) and Xinjiang Production and Construction Corps reported 200 newly confirmed cases. Among them, 52 cases were entered overseas (12 cases in Fujian, 11 cases in Guangdong, 6 cases in Yunnan, 5 cases in Inner Mongolia, 4 cases in Jiangxi, 4 cases in Sichuan, 2 cases in Beijing, 2 cases in Shanghai, 2 cases in Tianjin, 1 case in Jiangsu , 1 case in Shandong, 1 case in Shaanxi), including 3 cases from asymptomatic infections to confirmed cases (both in Guangdong); 148 local cases (52 cases in Guangxi, 49 cases in Gansu, 18 cases in Guangdong, 16 cases in Sichuan, Anhui, Anhui, Anhui, Anhui, Anhui In 7 cases, 3 cases in Shanghai, 2 cases in Jiangxi, 1 case of Inner Mongolia), 75 cases were converted from asymptomatic infections to confirmed cases (39 cases in Guangxi, 29 cases in Gansu, 5 cases in Sichuan, 1 case in Anhui, and 1 case in Guangdong). There are no new death cases. No new suspected cases.

31 provinces (autonomous regions, municipalities) and Xinjiang Production and Construction Corps reported 743 cases of asymptomatic infection, of which 65 were entered overseas, 678 cases of 678 (314 cases in Gansu, 135 cases in Guangxi, 77 cases in Anhui, 76 cases in Henan, Sichuan 28 cases, 14 cases of Tianjin, 14 cases in Shanghai, 7 cases of Jilin, 6 cases in Guangdong, 5 cases in Jiangxi, and 2 cases of Chongqing).

11 mutant strains have been reported in this round of epidemic

As of 24:00 on July 19th, according to incomplete statistics, 11 new types of Omikon -type mutant strains have been reported in 13 places in the territory.

Among them, there are 6 places for the evolutionary branch of Omikon BA.5, and 6 places for BA.2 evolutionary branch. Tianjin not only has the above two strains, but also reports the BA.4 evolution branch on July 6.

In terms of refining, there are 5 strains under the BA.2 evolution branch, including BA.2.3, BA.2.12.1, BA.2.38, BA.2, BA.2.2; There are 4 strains, namely BA.5, BA.5.2, BA.5.1, BA.5.2.1.

According to the information published by the Health Commission of various places, the correlation of this epidemic is not great, and the source is mostly foreign countries and regions.

Shanghai BA.5.2.1 mutant strain is an overseas entry -associated infection. 4 variation strains are inbound closed -loop management personnel and the BA.5.2 mutant strains in Xi'an also come abroad.

Omikon BA.4 and BA.5

Indeed, it shows the phenomenon of enhancement of communication capabilities

At the press conference, Dong Xiaoping, chief expert of the China Centers for Disease Control and Prevention, introduced that Omikon BA.4 and BA.5 have spreading capabilities. If they are compared with other evolutionary branches of Omikon, they do show the phenomenon of increasing communication capabilities.

BA.4, BA.5 sub -branch spread

Compared with other Omircong mutations, there are slightly increased

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.

The ninth edition prevention and control plan is optimized for prevention and control measures

Not relaxing

He Qinghua said at the press conference that the ninth edition of the prevention and control plan is the optimization of prevention and control measures, and it is by no means a relaxation of prevention and control measures.

He Qinghua introduced that the ninth version of the prevention and control plan is based on the characteristics of the latent period after the virus mutation, which corresponds to the time and control time of the isolation and control of risk personnel such as immigration personnel and close contacts. The use of centralized isolation resources has reduced the impact on the production and life of the masses. At the same time, the ninth edition of the prevention and control scheme encrypted the frequency of nucleic acid testing of risk personnel accordingly, which is conducive to the discovery of infection as soon as possible, and start the disposal early.

The key to the ninth edition of the prevention and control plan is: one is to control the focus of the control, the other is to implement the measures that should be implemented, and the third is to resolutely cancel the cancellation. Therefore, we must always tighten the string of the epidemic prevention and control, adhere to the overall strategy of "external prevention input, internal prevention and rebound" and the "dynamic clear zero" general policy. Coordinate the prevention and control of the epidemic and the development of economic and social development, protect the lives of the people's lives and health to the greatest extent, and minimize the impact of epidemic situation on economic and social development.

After the epidemic

To meet these conditions, there is no need to perform full nucleic acids

Wang Liping, a researcher at the China Centers for Disease Control and Prevention, introduced that the nucleic acid detection strategy in the ninth edition of the prevention and control scheme clearly clarifies the regional nucleic acid testing strategies in different scenarios and different scenarios, and clarified the regional nucleic acid test after the epidemic and normalized prevention and control. Strategy.

After the epidemic occurs, if the underworld research and judgment meet the following conditions: the source of the infection is clear; the dissemination chain is clear; no community transmission occurs, there is no need to conduct a full -member nucleic acid test on the area where the epidemic is required, and the nucleic acids that focus on the risk areas and the people who sometimes intersection with spaces and sometimes space intersect. Screen.

For example, after the underwriting and judgment, the dissemination chain is unclear, the risk places and risks are large, and the risk personnel are liquidity. When there is a risk of diffusion in the epidemic, the regional full -staff nucleic acid detection is required. The scope of regional nucleic acid testing, testing strategies and termination conditions in cities, general cities, and rural areas.

Can the risk -free isolation time be shortened? China Centers for Disease Control and Prevention responses

Faced with the new epidemic situation, the ninth edition of the prevention and control plan optimized the epidemic prevention policy. Specifically, the new version of the scheme will be modified from the "14 -day centralized isolation+7 Tianju Health Monitoring" to "7 -day centralized isolation+3 Heavenly Home Health Monitoring" from the past "14 -day centralized isolation isolation+7 Tianju Health Monitoring". In addition, the definition of risk areas and the corresponding regional nucleic acid detection strategy implementation standards are made clear requirements.

Wang Liping said that it will continue to collect new problems and new difficulties in the treatment of the epidemic in accordance with the overall measures of the ninth edition of the ninth edition of the ninth edition. For example, whether the isolation and control cycle and method of various types of risk personnel can be further shortened; how to carry out cross -regional risk personnel to investigate quickly and effectively to reduce the risk of cross -regional transmission of epidemic conditions as much as possible. Results of flow tone and risk research, analyze and study the scope of low risk areas, etc., and study, collect relevant data, further update and improve the prevention and control plan in my country, and strive to prevent the epidemic prevention and control on my country's economic and social development of our country. The impact of the lives of the masses is minimum.

Summer domestic personnel flow increases

The risk of local epidemic in various places increases

He Qinghua said that the global epidemic rebounded, the flow of domestic personnel increased in summer, the risk of local epidemic in various places increased, and the national epidemic prevention and control situation was still severe and complicated.All localities should continue to strictly follow the relevant requirements of the new crown pneumonia prevention and control plan (ninth edition), adhere to the principles of science, accuracy, and efficient prevention and control, implement various measures for external prevention input, and continuously improve the normalization prevention and control situationThe sensitivity of epidemic monitoring.After the epidemic occurs, the measures must be resolute and decisive, insist on fast -moving, and strive to control the epidemic in the minimum range in the shortest time, and resolutely prevent the occurrence of a large -scale epidemic.Newss
