Isolation time for arrivals

Recently, the domestic epidemic situation has generally been at a low level and fluctuated.

The recent local epidemics in my country have the following characteristics: First, the recent epidemic prevention and control results have been obvious, and the national epidemic situation is at a low level. Since June 18, China has reported fewer than 50 infections every day. In the past week (June 20-June 27), 198 cases of infection were voluntarily reported across the country, involving 24 cities in 10 provinces, with an average of 25 cases reported every day. Second, there are sporadic social infections in some areas, and the risk of community transmission still exists. The infected people have a wide range of activities before control, so some places have formed a relatively long elimination tailing period. Third, Omicron BA.2 is still the main virus strain in the local epidemic in my country, but we must be highly vigilant about the overseas spread of Omicron BA.4 and BA.5, because BA.4 and BA.4 have been recently discovered in imported cases overseas. BA.5, and there are signs of increase.

The quarantine control time for close contacts and entry personnel is adjusted from "147" to "73"

003010 Optimize and adjust the period and method of isolation management of risk personnel. The quarantine control time for close contacts and immigrants has been adjusted from "14 days of centralized isolation medical observation and 7 days of home health monitoring" to "7 days of centralized isolation medical observation and 3 days of home health monitoring", and the nucleic acid testing measures have been adjusted from "centralized isolation medical observation and 7 days of home health monitoring". Nucleic acid testing, nasopharyngeal swab collection, and double sampling and testing before lifting of isolation on days 1, 4, 7, and 14 were adjusted to "centralized isolation medical observation on days 1, 2, 3, 5, and 5." The secret control measures were adjusted from "7 days of centralized isolation medical observation" to "7 days of home medical observation", with nucleic acid testing on the 1st, 4th and 7th days.

Unify the demarcation standards for containment areas and medium- and high-risk areas, and delineate and prevent high, medium, and low-risk areas like this.

The ninth edition of the prevention and control plan unifies the delineation standards for closed control areas and medium- and high-risk areas. In the past, there were two types of standards for delineating risk areas: one was the standard for delineating high, medium, and low risk areas, and the other was the standard for delineating closed control areas, control areas, and prevention and control areas. The ninth edition of the prevention and control plan links the delineation standards and prevention and control measures of the two types of risk areas, integrates and uniformly uses the concepts of high, medium and low-risk areas, and forms a new risk area delineation and prevention and control plan.

High-risk areas refer to places where cases and asymptomatic infected people live, as well as workplaces and places with frequent activities and high risk of epidemic spread. In principle, high-risk areas are defined based on residential areas or villages, and risk areas can be judged and adjusted based on epidemiological survey results. High-risk areas adopt a "stay at home and provide door-to-door service" approach for closed control. A high-risk area can be downgraded to a medium-risk area if there are no new infections for 7 consecutive days, and it can be downgraded to a low-risk area if there are no new infections for 3 consecutive days. People in high-risk areas with cross-regional spillover will be put under centralized quarantine and medical observation for 7 days. Nucleic acid testing will be performed on days 1, 2, 3, 5, and 7 of centralized isolation.

Medium risk areas refer to areas where cases and asymptomatic infected persons stay and move within a certain period of time, and there may be a risk of epidemic spread, such as workplaces and event venues. Determine risk areas based on epidemiological investigation results. Medium-risk areas adopt the control measures of "keeping people in the area and picking up items at staggered peak times". If there are no new infections for 7 consecutive days, you can drop to a low-risk zone. People in medium-risk areas with cross-regional leakage will be subject to home medical observation for 7 days, and nucleic acid testing will be conducted on the 1st, 4th, and 7th day during the home medical observation period. Those who do not meet the conditions for home isolation shall undergo centralized isolation and medical observation.

Other areas in the counties (cities, districts, banners) where the medium- and high-risk areas are located are classified as low-risk areas. After the outbreak of the epidemic in counties (cities, districts, banners), after all medium and high-risk areas are lifted, the counties (cities, districts, banners) will

low-risk areas adopt "personal protection and avoid gatherings" Precautions. People in low-risk areas should have a 48-hour negative nucleic acid test certificate when leaving their area or city. For people in low-risk areas who travel across regions, there is no need to take isolation control measures, but they are required to complete two nucleic acid tests within 3 days and conduct personal health monitoring.

The shortening of the quarantine period for immigrants and close contacts is by no means a relaxation of prevention and control.

The ninth version of the prevention and control plan adjusts the isolation period for close contacts and outsiders from "14 days of centralized isolation and medical observation and 7 days of home health monitoring" to "7 days of centralized isolation and medical observation and 3 days of home health monitoring" "Monitoring" does not mean that the prevention and control measures are "relaxed", but that they are further optimized based on the popular characteristics of the Omiclone mutant strain. It is by no means a relaxation of prevention and control, which will not increase the risk of epidemic spread, but a manifestation of precise prevention and control, which requires higher standards and accuracy. The key to epidemic prevention and control is to control the key risks that should be managed and implement them in place, and resolutely cancel those that should be cancelled. Adhere to the general strategy of "rebounding from outside" and the general policy of "dynamic clearing", further improve the scientific nature and accuracy of epidemic prevention and control, make full use of resources, improve prevention and control efficiency, and coordinate epidemic prevention and control with economic and social development. The Comprehensive Team of the Joint Prevention and Control Mechanism of the State Council will send a working group to supervise local implementation.

Currently, the full text interpretation document of the ninth edition of the prevention and control plan has been released by the National Health Commission on the official website for everyone to download and review.

There are three considerations for announcing the new prevention and control plan at this time.

First, the epidemic situation changes. Currently, the COVID-19 epidemic continues to spread around the world.

Since the beginning of this year, the frequency of local epidemics has increased significantly, and the epidemic has spread widely, especially to the Yangtze River Delta, Pearl River Delta regions, Beijing-Tianjin-Hebei and border port cities. Our country is facing increasing pressure from "foreign prevention of imported cases and internal prevention of rebound", and the prevention and control situation has become more severe and complex. Over the past month, the overall situation of my country's epidemic prevention and control has steadily improved. The number of positive infections has continued to decline, and the number of epidemic areas has also decreased, creating a window for optimizing and adjusting prevention and control plans.

Second, the characteristics of virus mutation. Omiclone mutant strains have become the dominant epidemic strains imported and locally prevalent in my country. It was found that the average incubation period of omeclonal mutants was shortened, mostly 2-4 days, and most of them could be detected within 7 days.

Third, preliminary pilot study. According to the decisions and arrangements of the Party Central Committee and the State Council, the comprehensive team of the Joint Prevention and Control Mechanism of the State Council will carry out the joint prevention and control mechanism in 7 cities including Dalian, Suzhou, Ningbo, Xiamen, Qingdao, Guangzhou, and Chengdu from April to May.

The month-long pilot research work on optimizing COVID-19 prevention and control measures has obtained a large amount of scientific basis. At the same time, the prevention and control plan was revised based on the prevention and control practices in various places, especially the experience and lessons of large-scale epidemic handling in Shanghai, Jilin and other places, and with reference to the guidelines issued by the WHO in the first half of the year.

Encrypted frequency of nucleic acid testing for risk occupational groups

Based on the previous normalized monitoring, the ninth version of the prevention and control plan has encrypted the frequency of nucleic acid testing for risk occupational groups. People who have direct contact with items and the environment (such as cross-border transportation drivers, cleaners, maintenance personnel, personnel handling imported items at ports, front-line personnel in customs and immigration management departments who have direct contact with immigrants and items, etc.), staff in centralized isolation places , medical staff at fever clinics in designated medical institutions and general medical institutions will conduct nucleic acid tests once a day. For employees with dense working environments, frequent contact with people, and high mobility (such as express delivery, takeout, hotel services, decoration and loading and unloading services, transportation services, staff in shopping malls, supermarkets, and farmers’ markets, etc.) as well as general medical institutions. Staff in other departments outside the outpatient clinic will conduct nucleic acid testing twice a week. After a local epidemic occurs, the frequency of nucleic acid testing will be increased based on the risk of epidemic spread.

When encountering the problem of "increasing the number of layers" in epidemic prevention and control, there are these channels to report

The comprehensive team of the Joint Prevention and Control Mechanism of the State Council has a special team to rectify the problem of "increasing the number of layers" and its members The unit will carefully accept and verify the "layered overweighting" issues reported by the masses.

In order to effectively solve the problem of local "layered overloading" reported by people in various places, the joint prevention and joint control mechanism of the State Council also requires the joint prevention and joint control mechanisms at the provincial level to follow the structure of the special class of the comprehensive team of the joint prevention and joint control mechanism of the State Council , set up a special class at the provincial level to rectify the problem of "overweighting at all levels". At the same time, the joint prevention and control mechanisms at the provincial level are required to establish as soon as possible an effective channel for people in the province to complain and report issues such as simplification, "one size fits all" and "layered overloading" of epidemic prevention and control, and promptly announce it to the public, collect, verify and handle the issues in the province Clues on relevant issues reported by the masses.
