Expert detailed explanation of the ninth edition prevention and control plan: not relaxing and control, but more scientific and accurate

Cover news reporter Shao Meng

"The ninth edition of the prevention and control scheme is the optimization of prevention and control measures. It is by no means relaxing and controlling. The key is to control the focus of the control, the implementation of the implementation, and the resolute cancellation of the cancellation."

On July 14, Liu Qing, director of the Defense Division of the CDC of the National Health and Health Commission, emphasized in an interview with the cover news that adjustments do not mean "relaxation", but to further improve the scientific and precise of the epidemic prevention and control sex.

On June 27, the State Council responded to the new type of coronary virus pneumonia. The period and method of isolation management, uniformly define standards in the control areas and high -risk areas, and improve the requirements of epidemic monitoring.

What are the basis for these adjustments? What are the regional nucleic acid detection strategies in different scenarios? Is there a low -risk zone where there is no epidemic? In response to these questions, Liu Qing, Director of the Defense Department of the CDC of the National Health and Health Commission, Wang Liping, researcher at the Central Disease Control Infectious Disease Management Office, and the researcher of the China CDC Infectious Disease Management Office, Chang Zhaorui gave detailed answers in an interview.

Why shorten the time to observation and observation of the entry and entry personnel?

Adjustment according to the characteristics of Omikon

According to Liu Qing, the ninth edition of the prevention and control plan is clear that the time of secret and immigration isolation and control time from "14 days of centralized isolation+7 Heavenly House Health Monitoring" to "7 -day centralized isolation+3 Heavenly Home Health Monitoring" The secret control measures are adjusted from "7 -day concentration isolation" to "7 Heavenly House isolation."

What is the basis for this adjustment? Wang Liping said that from April to May, the State Council ’s joint prevention and control mechanism comprehensive group carried out pilot research on the optimization of new coronary pneumonia epidemic prevention and control measures in some areas. Studies have found that the average incubation period of Omikon variants is shortened, mostly 2-4 days, and most of them can be detected within 7 days. Based on the results of the research and the practice of multiple places, the ninth edition of the prevention and control scheme optimized the time limit and method of isolation control and control of the epidemic -related risk personnel.

"Such adjustments are further optimized based on the popular characteristics of the Omeck Rong mutant strains. It will not increase the risk of epidemic transmission, which is a manifestation of precise prevention and control." Wang Liping said.

Liu Qing also emphasized that it is necessary to further improve the scientific and accuracy of the epidemic prevention and control, protect the safety and physical health of the people to the greatest extent, and minimize the impact of epidemic on economic and social development.

Why optimize regional nucleic acid detection strategies?

Fight at the minimum social cost against the epidemic situation

The ninth edition of the prevention and control scheme clearly clearly detects different scenarios and different scene nucleic acid testing strategies. For cities, cities, and rural areas above millions of people, cities, and general cities, and rural areas, regional nucleic acid testing strategies after the epidemic and normalization prevention and control are clearly defined.

"This is a very large adjustment of science and accuracy of the nine version of the prevention and control plan." Wang Liping introduced that after the epidemic, the following conditions are determined to meet the following conditions: the source of the infection is clear; the dissemination chain is clear; no community transmission occurs, no need to be right to be right. The area that occurs in the epidemic conducts a whole nucleic acid testing, focusing on the risk -regional and sometimes space intersection personnel to conduct 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.

Among them, when the provincial capital cities and cities above tens of millions of population are risked by diffusion in the epidemic, after 3 days and 3 days of inspection of social infection in the area where the epidemic is located, a full -member nucleic acid test is carried out in 3 days. Stop all nucleic acid detection.

Wang Liping pointed out that if there is no positive for 3 consecutive days, it means that the risk of community communication is relatively low. Because the virus excretion is intermittent, it is reasonable to do it once every 3 days.

What are the changes in risk zone delineation standards?

Unified control zone and mid -to -high risk zone

In addition to the adjustment of the risk -free policy, the ninth edition prevention and control plan corresponds to the high, middle and low -risk areas and the control areas, control areas, and prevention and control measures. Essence

Chang Zhaorui emphasized that the division of high, middle and low risk areas is divided into counties (cities, districts, and flags) that occurred in the epidemic. Low -risk zone refers to other areas (cities, districts, flags) where the high -risk zone is located. The risk of high school risk zones is low, but there are certain risks of counties (cities, districts, and flags) without epidemic conditions.

For low -risk areas, "personal protection and avoiding gathering" prevention measures. Low -risk areas to leave the area or city in the area should hold a 48 -hour nucleic acid test negative certificate. For cross -regional low -risk regions, 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 health monitoring.

It is worth noting that except for high, middle and low risk areas, counties (cities, districts, flags), which occurred without epidemic, implemented normalized prevention and control measures in the entire region.
