"New Coronatte Pneumonia Pneumonia Prevention and Control Plan (Ninth Edition)" has recently been released, and has adjusted the scientific and accurate of epidemic monitoring, the isolation management of risk personnel, and the standards for medium and high risk regions to further improve the scientific and accuracy of epidemic prevention and control.

What is the basis for the revision of the prevention and control scheme?

What are the changes in the division of different risk areas?

Does the latest mutant strains affect the existing prevention and control measures?

Why revise the prevention and control plan?

More scientific and accurate

Liu Qing, director of the Infectious Disease Prevention and Control Division of the National Health and Health Commission's Disease Control Bureau, said that there are three considerations of the amendments to the amendment of the prevention and control plan:

First, the change of the epidemic situation

The new coronary pneumonia epidemic is still continuously popular worldwide. Since this year, the frequency of local epidemic conditions in the country has increased significantly. The epidemic situation has a wide range of regions. The pressure of China's foreign prevention input and internal defense rebound has continued to increase, and the situation of prevention and control is more severe and complicated.

Second, the characteristics of virus mutation

As an advantageous popular strain, the incubation period of Omikon is shortened, the propagation ability and concealment are stronger, the transmission speed is faster, which brings new challenges to the prevention and control of the epidemic.

Third, the preliminary pilot work results and epidemic prevention and control practice

The comprehensive group of the State Council ’s joint prevention and control mechanism has carried out a 4 -week epidemic prevention and control measures in Dalian, Suzhou, Ningbo, Xiamen, Qingdao, Guangzhou, and Chengdu to optimize the pilot research work. At the same time, it has fully absorbed the experience of prevention and control work and epidemic disposal experience in various places.

"The ninth edition of the prevention and control plan is the optimization of prevention and control measures, and it is by no means relaxing prevention and control." Liu Qing said that the key is to control the key points, the implementation of the implementation, and the resolute cancellation of the cancellation. Further improve the scientific and accuracy of epidemic prevention and control.

Why adjust the time limit for risk personnel?

Virus incubation period shortened

The pilot research on the optimization of epidemic prevention and control measures carried out from April to May found that the average incubation period of Omikon variants was shortened, mostly 2 days to 4 days; most of them could be detected within 7 days.

"In order to further improve the scientific and accuracy of the prevention and control measures of the new crown pneumonia, based on the results of research and the domestic prevention and control practice, the ninth edition of the prevention and control scheme of the epidemic -related risk personnel optimized the time limit and method of the isolation and control of the epidemic -related risk. Wang Liping, a researcher at the Infectious Disease Management Office of the China Centers for Disease Control and Prevention.

Adjust the time and control time of close contact and immigration personnel from "14 days of centralized isolation+7 Heavenly House Health Monitoring" to "7 -day concentration isolation+3 Heavenly Home Health Monitoring". Adjust to "7 Heavenly House Isolation" ...

"Such adjustments are further optimized to prevent control measures based on the popular characteristics of Omikon's mutant strains. It will not increase the risk of epidemic transmission, which is a reflection of precise prevention and control." Wang Liping said.

When will the whole staff nucleic acid test be started?

Clearly define the conditions

In different scenarios, the regional nucleic acid detection strategy should be different -the ninth edition prevention and control plan further clarifies this. The plan is aimed at provincial capital cities and cities with more than millions of population, general cities, and rural areas, and the regional nucleic acid testing strategies after the epidemic and normalization are clearly clarified.

Wang Liping introduced that after the epidemic, if the flow was judged to meet the conditions such as "clear sources of infection", "clear dissemination chain", "no community communication" and other conditions. Sometimes people who intersection with spaces carry out nucleic acid screening.

For example, after the underwriting, the dissemination chain is unclear, the risk places and risks are many, and the risk personnel are liquidity. When there is a risk of diffusion in the epidemic, the entire nucleic acid test of the area needs to be started. The scheme clearly defines the scope of detection, detection strategies, and termination conditions of different areas.

How to divide the high, middle and low risk zone?

No epidemic county implements normalized prevention and control

According to the ninth edition of the prevention and control plan, the high and middle -level risk areas are divided into counties (cities, districts, flags) with epidemic conditions. The county (city, district, flag) that does not occur in the epidemic has implemented normalized prevention and control measures in the whole region.

High -risk zone refers to

The residence of cases and asymptomatic infections, as well as the workplace, and active places with high risk of epidemic dissemination, in principle, the residential communities or villages are determined. Research and adjust the area of ​​risk. The high -risk zone adopts the control measures of "not leaving home and on -site services". For high -risk areas of high -risk areas, 7 -day centralized isolation medical observation is adopted.

Mid -risk zone refers to

Cases and asymptomatic infections stay and move for a certain period of time, and may have a workplace and area such as the risk of epidemic dissemination. The central risk zone adopts the management and control measures of "people who do not get out of the area and peaks". For personnel in the central risk zone overflowing, the 7 Heavenly Home Observation Medical Observation is adopted.

Low risk zone refers to

Other areas (cities, districts, flags) where the high risk zone is located. The low -risk zone takes the prevention measures of "personal protection and avoiding gathering". Low -risk zones who go out across areas should hold a 48 -hour nucleic acid test negative certificate when leaving. For low -risk areas who are out of the region, there is no need to take isolation control measures, but it is required to complete two nucleic acid detection within 3 days and do a good job of personal health monitoring. Does the latest mutant strains have an impact?

The prevention and control plan is still applicable

Recently, the branch of Omikon BA.5 Asian is becoming the major epidemic strains in the world, and it has triggered a local clustering epidemic in my country. Dong Xiaoping, chief expert of the China Centers for Disease Control and Prevention, said that compared with other Omikonia branches, the pathogenic force of BA.5 has not changed significantly, and the ninth edition of the ninth edition is still applicable.

The ninth edition of the prevention and control scheme will mention the higher position of the virus, reflect the layered nucleic acid screening scheme, the frequency of nucleic acid testing of the encrypted risk professional population, and increase the antigen detection as a supplementary method for epidemic monitoring.

"These measures in the ninth edition of the prevention and control plan are effective for BA.4 and BA.5 Asian branches." Dong Xiaoping said.
