In order to further guide various localities in the prevention and control of new coronavirus pneumonia , the State Council responds to the new coronavirus The Comprehensive Team of the Joint Prevention and Control Mechanism for the Pneumonia Epidemic has formulated a new coronavirus pneumonia prevention and control plan (ninth edition). Recently, the official website of the National Health Commission of China announced the latest version of the prevention and control plan.
Interpretation of the "Novel Coronavirus Pneumonia Prevention and Control Plan (Ninth Edition)"
The ninth edition of the prevention and control plan is based on the eighth edition and is based on the characteristics of the Omikron variant strain, such as its rapid spread and strong concealment. Revision. The main revisions are as follows:
1. Optimize and adjust the isolation management period and method of risk personnel
Adjust the isolation and control time of close contacts and immigrants from "14 days of centralized isolation medical observation + 7 days of home health monitoring" to "7 days of centralized quarantine Isolation medical observation + 3 days of home health monitoring” . nucleic acid testing measures were adjusted from "nucleic acid testing on the 1st, 4th, 7th and 14th days of centralized isolation medical observation, collecting nasopharyngeal swabs, and double sampling and testing before lifting the isolation" to "centralized isolation medical observation on the 1st, 2nd and 3rd days" , 5, 7 days and the 3rd day of home health monitoring for nucleic acid testing and collection of oropharyngeal swabs ". Dual collection and testing are not required before the centralized isolation medical observation is lifted. The close control measures for
close contacts have been adjusted from "7 days of centralized isolation and medical observation" to "7 days of home isolation and medical observation", with nucleic acid testing on the 1st, 4th and 7th days.
2. Unify the delineation standards of closed control areas and medium- and high-risk areas
The demarcation standards and prevention and control measures for the two types of risk areas are connected and corresponding, and the concept of medium- and high-risk areas is uniformly used to form a new risk area delineation and control plan.
High-risk areas implement "door-to-door service without leaving home" . There are no new infections for 7 consecutive days and are reduced to medium-risk areas. Medium-risk areas have no new infections for 3 consecutive days and are reduced to low-risk areas. In other areas, 7-day centralized isolation and medical observation measures are implemented for those who have a history of traveling to high-risk areas in the past 7 days.
The medium-risk area implements "staying in the area and picking up items at staggered peaks" , and has been reduced to a low-risk area with no new infections for 7 consecutive days. Other regions have adopted 7-day home medical observation measures for those who have traveled to medium-risk areas in the past 7 days.
Low-risk areas refer to other areas in the counties (cities, districts, banners) where medium- and high-risk areas are located, implementing "personal protection and avoidance of gatherings" . In other areas, people who have traveled to low-risk areas in the past seven days are required to complete two nucleic acid tests within three days.
3. Improve the epidemic monitoring requirements
Encrypt the frequency of nucleic acid testing for risk occupational groups, adjust the nucleic acid testing of personnel in direct contact with entry personnel, items, and the environment to once a day. For employees with dense personnel, frequent contacts, and high mobility Nucleic acid testing is adjusted to twice a week.
Adding antigen testing as a supplementary method for epidemic monitoring . Primary medical and health institutions can increase antigen testing for suspicious patients and people in medium- and high-risk areas when handling the epidemic.
4. Optimize regional nucleic acid testing strategies
Clarify regional nucleic acid testing plans for different population sizes. Target provincial capital cities, cities with a population of more than 10 million, general cities, and rural areas. After the outbreak, whether the source of infection is clear, whether there is a risk of community transmission, and The scope and frequency of regional nucleic acid testing will be determined based on factors such as whether the chain of transmission is clear and based on the risk and the principle of classification.
