Adjust the control time of close contacts and entry personnel from "14 days of centralized isolation medical observation +7 days of home health monitoring" to "7 days of centralized isolation medical observation +3 days of home health monitoring", take nucleic acid detection measures for "1, 4, 7 and 14 days of centralized isolation medical observation" and collect nasopharyngeal swabs. The control measures of close contact were changed from "7-day centralized isolation medical observation" to "7-day home isolation medical observation", and nucleic acid detection was carried out on 1, 4 and 7 days.
Two, unified seal control zone and high risk zone delineation standards.
The two types of risk area delineation standards and prevention and control measures are connected and corresponding to each other, and the concept of medium and high risk areas is used uniformly to form a new risk area delineation and control scheme. In high-risk areas, "home-to-home service" was implemented, and no new infections fell to medium-risk areas for 7 consecutive days, and no new infections fell to low-risk areas for 3 consecutive days.
In other areas, people with a history of living in high-risk areas in the past 7 days were subjected to 7-day centralized isolation medical observation. In the middle-risk area, the practice of "staying out of the area and taking things at the wrong peak" was implemented, and no new infections were reduced to the low-risk area for 7 consecutive days. In other areas, people living in medium-risk areas in the past 7 days will be observed at home for 7 days.
Low-risk areas refer to other areas in the counties (cities, districts and banners) where high-risk areas are located, and "personal protection and avoidance of gathering" are implemented. In other areas, people living in low-risk areas in the last 7 days are required to complete nucleic acid testing twice within 3 days.
Third, improve the requirements for epidemic monitoring.
Encrypt the frequency of nucleic acid detection for high-risk occupational groups, adjust the nucleic acid detection for those who have direct contact with entry personnel, articles and the environment to 1 time per day, and adjust the nucleic acid detection for employees with dense personnel, frequent contact and strong mobility to twice a week. Adding antigen detection as a supplementary means of epidemic monitoring, grass-roots medical and health institutions can add antigen detection to suspicious patients and people in high-risk areas when dealing with the epidemic.
Fourth, optimize the regional nucleic acid detection strategy.
Clarify the regional nucleic acid detection schemes of different population sizes, judge whether the source of infection is clear, whether there is community transmission risk and whether the transmission chain is clear after comprehensive epidemic situation, and determine the scope and frequency of regional nucleic acid detection according to the principle of risk and grading.
Notice on Issuing the Prevention and Control Plan of novel coronavirus (Ninth Edition);
Joint prevention and control mechanism [2022] No.765438 +0
Provinces, autonomous regions, municipalities directly under the Central Government and Xinjiang Production and Construction Corps should respond to the joint prevention and control mechanism of novel coronavirus epidemic (leading group and headquarters), and the State Council should respond to the members of the joint prevention and control mechanism of novel coronavirus epidemic, China CDC:
In order to further guide all localities to do a good job in prevention and control of novel coronavirus, and to cope with the comprehensive group of joint prevention and control mechanism of novel coronavirus epidemic, the State Council formulated the Prevention and Control Plan for novel coronavirus (Ninth Edition). Is issued to you, please earnestly organize the implementation. If all localities and departments have relevant suggestions in the implementation process, please give timely feedback to the comprehensive group of institutions.
