China News Service, June 28. According to the website of the National Health and Health Commission, the State Council's Comprehensive Team of the Joint Prevention and Control Mechanism for the New Coronavirus Pneumonia Epidemic Outbreak issued the "New Coronavirus Pneumonia Prevention and Control Plan (Ninth Edition)" on the 27th.

Among them, it is clear that the isolation and control time of close contacts and inbound personnel will be adjusted 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".

  According to reports, in order to further guide the scientific and accurate prevention and control of new coronavirus pneumonia in various places, after carefully summarizing the prevention and control work practices after the issuance of the "New Coronavirus Pneumonia Prevention and Control Plan (Eighth Edition)", especially for Omic On the basis of the characteristics of rapid transmission and strong concealment of Rong mutant strains, the comprehensive group of the State Council's joint prevention and control mechanism for the new coronavirus pneumonia epidemic organized the revision and formed the "New Coronary Virus Pneumonia Prevention and Control Plan (Ninth Edition)", which was fully implemented. The general strategy of "preventing import from abroad and preventing rebound from within" and the general policy of "dynamic clearing" are to earnestly safeguard the lives and health of the people, and to coordinate epidemic prevention and control and economic and social development to the greatest extent possible.

The main revisions are as follows:

The first is to optimize and adjust the isolation management period and method of risk personnel.

Adjusted the isolation and control time for close contacts and inbound personnel from "14-day centralized isolation medical observation + 7-day home health monitoring" to "7-day centralized isolation medical observation + 3-day home health monitoring", and nucleic acid testing measures were changed from "centralized isolation medical observation". Nucleic acid testing on the 1st, 4th, 7th, and 14th days of observation, collection of nasopharyngeal swabs, and double-collection and double-examination before release from quarantine” was adjusted to “Centralized isolation medical observation on the 1st, 2nd, 3rd, 5th, 7th days and home health monitoring on the first day. 3-day nucleic acid test, collection of oropharyngeal swabs", double sampling and double testing are not required before the release of centralized isolation medical observation.

The close control measures have been adjusted from "7-day centralized isolation medical observation" to "7-day home isolation medical observation", and nucleic acid testing on the 1st, 4th, and 7th days.

The second is to unify the standards for the delineation of closed control areas and medium and high risk areas.

The two types of risk area delineation standards and prevention and control measures should be linked and corresponded, and the concept of medium and high risk areas should be uniformly used to form a new risk area delineation and control plan.

The high-risk area implements "stay-at-home, door-to-door service". No new infections for 7 consecutive days have been reduced to medium-risk areas, and medium-risk areas with no new infections for 3 consecutive days have been reduced to low-risk areas.

In other areas, people with a history of living in high-risk areas within the past 7 days will be subject to 7-day centralized isolation and medical observation measures.

The medium-risk area implements "staying out of the area and picking things at different peaks", and no new infections for 7 consecutive days have been reduced to a low-risk area.

In other areas, people with a history of living in medium-risk areas within the past 7 days will be subject to 7-day home medical observation measures.

Low-risk areas refer to other areas in the counties (cities, districts, and flags) where medium- and high-risk areas are located, and "personal protection and avoidance of gatherings" are implemented.

In other areas, people with a history of living in low-risk areas within the past 7 days are required to complete 2 nucleic acid tests within 3 days.

The third is to improve the epidemic monitoring requirements.

The frequency of nucleic acid testing for high-risk occupational groups will be adjusted, and the nucleic acid testing of personnel who have direct contact with inbound personnel, articles, and the environment will be adjusted to once a day, and the nucleic acid testing of employees with dense personnel, frequent contacts, and high mobility will be adjusted to twice a week. .

Antigen testing is added as a supplementary means of epidemic monitoring. Primary medical and health institutions can increase antigen testing for suspicious patients and people in medium and high-risk areas when dealing with the epidemic.

The fourth is to optimize the regional nucleic acid detection strategy.

Clarify nucleic acid testing plans for regions with different population sizes, and conduct research and judgments on factors such as provincial capital cities, cities with a population of more than 10 million, general cities, and rural areas, whether the source of infection is clear after the outbreak, whether there is a risk of community transmission, and whether the chain of transmission is clear. According to the size of the risk, according to the principle of classification and classification, determine the scope and frequency of regional nucleic acid testing.
