In order to further guide local authorities in the prevention and control of COVID-19, and on the basis of carefully summarizing the prevention and control practices after the Eighth edition of COVID-19 Prevention and Control Protocol, especially for the characteristics of Omicron variant, such as fast transmission speed and strong occult,

Under the State Council shall deal with the new coronavirus pneumonia outbreak zone spreading mechanism maintaining organization revised formed the new coronavirus pneumonia prevention and control program (ninth edition) ", the full implementation of "outside the input, the rebound" total strategy and "dynamic reset" general policy, to safeguard people's life safety and body health, as a whole the epidemic prevention and control and maximum economic and social development.

Compared with the eighth edition, the main revisions include:

I. Optimize and adjust the isolation management period and methods of risk personnel

The quarantine control time of close contacts and inbound travelers was changed from "14-day centralized medical observation and 7-day home health monitoring" to "7-day centralized medical observation and 3-day home health monitoring". Nucleic acid testing measures were changed from "centralized medical observation and isolation" on the 1st, 4th, 7th, and 14th days. Nasopharyngeal swabs were collected.

"Double sampling and double testing before the release of isolation" was changed to "nucleic acid testing and oropharyngeal swab collection on the 1st, 2nd, 3rd, 5th, 7th day of centralized isolation and medical observation and the 3rd day of home health monitoring", and double sampling and double testing were not required before the release of centralized isolation and medical observation.

The bonding control measures were changed from "7-day centralized isolation and medical observation" to "7-day home isolation and medical observation", and nucleic acid testing was performed on the first, fourth, and seventh days.

Second, unified seal control area and high and medium risk area demarcation standards

The delineation standards and prevention and control measures of the two types of risk areas are connected and corresponding, the concept of medium-high risk areas is unified, and a new risk area delineation and control scheme is formed.

The high risk area implemented the "stay at home, door-to-door service", and the medium risk area without new infection for 7 consecutive days was reduced to the medium risk area, and the medium risk area without new infection for 3 consecutive days was reduced to the low risk area.

In other regions, people with a history of travel in high-risk areas within the past seven days should be quarantined for medical observation for seven days.

The medium-risk area has been upgraded to a low-risk area with no new infections for 7 consecutive days.

In other regions, 7-day home medical observation measures were taken for those with a history of travel in medium-risk areas within the past 7 days.

The low risk area refers to the other areas in the county (city, district, flag) where the medium and high risk area is located, and "personal protection and avoidance of gathering" is implemented.

In other regions, people with a history of travel in low-risk areas within the past 7 days are required to complete two nucleic acid tests within 3 days.

Iii. Improving the requirements for epidemic surveillance

The frequency of nucleic acid testing for professionals at risk of encryption will be adjusted to once a day for those who have direct contact with inbound personnel, articles and the environment, and twice a week for those who have dense personnel, frequent contact and high mobility.

Additional antigen testing can be used as a supplementary means for epidemic surveillance. Primary medical and health institutions can add antigen testing to suspicious patients and people in medium-high risk areas when dealing with the epidemic.

4. Optimize regional nucleic acid detection strategy

Clear different population scale regional nucleic acid detection scheme, in view of the provincial capital cities and being more than population, general urban and rural areas, comprehensive outbreak after infection source is clear, if there is a community spread risk and chain of transmission is clear, according to the risk, according to the principle of hierarchical classification, determine the area of nucleic acid detection range and frequency.
