Downgrade to low-risk areas

There have been no new infections for 7 consecutive days, and all personnel in the risk area completed a round of nucleic acid screening on the 7th day and all were negative, and the area was reduced to a low-risk area. In low-risk areas, "personal protection and avoidance of gatherings" are implemented; in other areas, people who have traveled to low-risk areas in the past 7 days are required to complete two nucleic acid tests within 3 days.

In June 2022, the Comprehensive Team of the Joint Prevention and Control Mechanism of the State Council in response to the new coronavirus pneumonia epidemic issued the "Novel Coronavirus Pneumonia Prevention and Control Plan (Ninth Edition)" to clarify the delineation of risk areas for the new coronavirus pneumonia epidemic. and lifting criteria:

1. High-risk areas

Delimitation criteria: residences of cases and asymptomatic infected persons, as well as work places and activities with frequent activities and high risk of epidemic transmission Areas such as areas are designated as high-risk areas. In principle, residential areas (villages) are used as units, and the scope of risk areas can be adjusted based on the results of flow surveys.

Lifting criteria: There are no new infections for 7 consecutive days, and all people in the risk area on the 7th day have completed a round of nucleic acid screening and all are negative, and the area is reduced to a medium-risk area; there are no new infections for 3 consecutive days Infected people are moved to low-risk areas.

Control measures for people with spillover risks: Personnel with a 7-day history of staying in high-risk areas will be subject to 7-day centralized isolation and medical observation at the destination. For spillover personnel in high-risk areas, a 7-day centralized isolation medical observation will be carried out, and a nucleic acid test will be conducted on the 1st, 2nd, 3rd, 5th and 7th days of the centralized isolation medical observation (the management period starts from the time of leaving the risk area).

2. Medium-risk areas

Delimitation standards: areas where cases and asymptomatic infected persons stay and move for a certain period of time, and where there may be risks of epidemic spread, such as work places and activity areas, It is classified as a medium-risk area, and the scope of the risk area is demarcated based on the results of flow surveys.

Lifting criteria: There are no new infections for 7 consecutive days, and all personnel in the risk area on the 7th day have completed a round of nucleic acid screening and all are negative, and the area is reduced to a low-risk area.

Control measures for people at risk of spillover: Personnel with a 7-day history of staying in medium-risk areas will be subject to 7-day home isolation medical observation at the destination, and medical observation will be carried out once on the 1st, 4th and 7th day at home. Nucleic acid testing; if the conditions for home isolation and medical observation are not met, 7 days of centralized isolation and medical observation will be adopted (the management period starts from the time of leaving the risk area).

3. Low-risk areas

Delimitation standards: Other areas in the county (city, district, banner) where the medium- and high-risk areas are located are low-risk areas.

Lifting criteria: There are no medium or high-risk areas in the county (city, district, banner), and low-risk areas will be adjusted to normalized prevention and control.

Control measures for people with spillover risks: For those who have a history of staying in low-risk areas for 7 days, nucleic acid tests will be completed twice within 3 days (two tests in three days).

During the epidemic management process, if individual cases and asymptomatic infections pose a low risk of transmission to places of residence, work, and activity areas, and close contacts have been controlled in a timely manner, and it is determined that there is no risk of community transmission, they may not be classified as Define the risk area. Counties (cities, districts, banners) where local epidemics have not occurred must effectively implement regular epidemic prevention and control measures and do not need to delineate risk areas.

Legal basis: "Law of the People's Republic of China on the Prevention and Control of Infectious Diseases"

Article 30

Disease prevention and control institutions, medical institutions and procurement agencies When blood supply institutions and their personnel perform their duties discover an infectious disease epidemic stipulated in this Law or discover an outbreak or epidemic of other infectious diseases or an infectious disease with unknown cause, they shall follow the principle of local management of epidemic reporting and follow the provisions of the State Council or the Health Administration of the State Council. Reporting within the content, procedures, methods and time limits specified by the department. Military medical institutions provide medical services to the public and when discovering an infectious disease epidemic specified in the preceding paragraph, they shall report it in accordance with the regulations of the health administrative department of the State Council.
