Yesterday, the Comprehensive Team of the Joint Prevention and Control Mechanism of the State Council released the "Novel Coronavirus Pneumonia Prevention and Control Plan (Ninth Edition)".
Lei Zhenglong, deputy director of the National Health Commission's Bureau of Disease Control and Level 1 Inspector, introduced that the ninth version of the "Plan" has major changes in three aspects - optimizing and adjusting the isolation management period and methods of risk personnel, and unifying the closure of control areas and medium- and high-risk areas. Set standards for district delineation and improve relevant requirements for epidemic monitoring. The relevant change "is not about relaxing prevention and control, but requiring more standardization, accuracy and speed." What details have changed in the new version of
's "Plan" compared to the previous one?

1. The average incubation period of the virus is shortened
[Eighth Edition] The incubation period of new coronavirus pneumonia is 1-14 days, mostly 3-7 days; 1-2 days before onset and early onset of onset are relatively contagious.
[Ninth Edition] The average incubation period of Omicron mutant strains is shortened, mostly 2-4 days, with stronger transmissibility, faster transmission speed, lower infectious dose, weakened pathogenicity, and stronger immunity Escape ability.
2. Expansion of the scope of vaccination population
[Eighth Edition] Do a good job in occupational exposure to groups with higher risks, people at risk of infection abroad, personnel who maintain normal production and life operations of society, and key occupations that maintain the basic operation of society. , border ports and other key areas, service industries, labor-intensive industries, college students and various school staff and other key groups of people aged 18 and above are vaccinated, and other people aged 18 and above who are willing to be vaccinated Vaccination.
[Ninth Edition] The scope of vaccination for the new coronavirus vaccine has been expanded to those over 3 years old, adhering to the principles of informed consent, and voluntariness, and encouraging all eligible people over 3 years old without vaccination contraindications. For eligible target groups over 18 years old, one dose of homologous booster vaccination or sequential booster vaccination is not allowed. They cannot receive homologous booster vaccination and sequential booster vaccination at the same time. Focus on increasing the full vaccination rate and enhanced immunization rate for groups at high risk of severe illness, such as those aged 60 and above.

3. Adjustment of management methods for close contacts
[Eighth Edition] Close contacts will be subject to 14 days of centralized isolation medical observation. During the first period of centralized isolation medical observation, , 4, 7 and 14 days respectively conduct a nucleic acid test . After the isolation is lifted, home health monitoring will be carried out for 7 days. During this period, the body temperature and symptoms will be monitored, movement will be reduced, personal protection will be taken when going out, and people will not participate in gathering activities. A nucleic acid test will be carried out on the 2nd and 7th days.
[Ninth Edition] Management measures of "7 days of centralized isolation medical observation + 3 days of home health monitoring" will be adopted for close contacts. During the home health monitoring period, they will not go out. If necessary, take personal protection when going out for special circumstances such as medical treatment, and try to avoid Take public transportation. A nucleic acid test will be carried out on the 1st, 2nd, 3rd, 5th and 7th days of centralized isolation medical observation, and a nucleic acid test will be carried out on the 3rd day of home health monitoring. When a large-scale epidemic occurs, in order to alleviate the serious shortage of resources in centralized isolation points, the measures of "5 days of centralized isolation medical observation + 5 days of home isolation medical observation" can be adopted for close contacts. The first, second and third steps of centralized isolation medical observation are A nucleic acid test will be carried out every 5 days, and a nucleic acid test will be carried out on the 2nd and 5th days of home isolation medical observation. The period of isolation management is calculated from the last exposure. After the centralized isolation is lifted, people should return to their place of residence in a "point-to-point" closed loop.
4. Adjustments to the control methods for entry personnel
[Eighth Edition] Implement 14-day isolation medical observation measures for entry personnel. For immigrants who have completed remote nucleic acid testing (those with a history of vaccination only need to have a negative nucleic acid test), those who have closed transfer management conditions, home isolation conditions (with separate rooms and separate bathrooms) and can carry out precise community control can be admitted on a voluntary basis. Implement "7+7" isolation medical observation measures. After the isolation is lifted, home health monitoring will be carried out for 7 days. During this period, the body temperature and symptoms will be monitored, the movement will be reduced, personal protection will be taken when going out, and people will not participate in gathering activities. A nucleic acid test will be carried out on the 2nd and 7th days.
[Ninth Edition] The management measures of "7 days of centralized isolation medical observation + 3 days of home health monitoring" will be implemented for entry personnel, and a nucleic acid test will be conducted on the 1st, 2nd, 3rd, 5th, and 7th days of the centralized isolation medical observation. Carry out a nucleic acid test on the third day of home health monitoring. Do not go out during the home health monitoring period. For special circumstances such as medical treatment, you must take personal protection when going out, and try to avoid taking public transportation.

5. Uniformly use the medium and high-risk area delineation and control plan
The ninth version of the "Plan" divides two types of risk areas Establish standards and coordinate prevention and control measures, uniformly use the concept of medium and high risk areas, and form a new risk area delineation and control plan:
After a local epidemic occurs, based on the activity trajectory of cases and asymptomatic infections and the spread of the epidemic Risk magnitude delineates high, medium, and low risk areas. Classify the residences of cases and asymptomatic infected persons, as well as work places and activity areas with frequent activities and high risk of epidemic transmission, as high-risk areas, and implement "door-to-door services without leaving home"; Work where infected people stay and move for a certain period of time and may pose a risk of spreading the epidemic Areas such as places and activity areas are classified as medium-risk areas, and "people are not allowed to leave the area and pick up items at staggered peaks"; other areas in the counties (cities, districts, banners) where medium- and high-risk areas are located are low-risk areas, and "personal protection" is implemented. ", avoid gatherings." People in low-risk areas should hold a 48-hour negative nucleic acid test certificate when leaving the city.
6. Optimize regional nucleic acid testing strategy
[Eighth Edition] Based on the epidemic situation and epidemiological survey results, carry out risk assessment, determine the scope and sequence of nucleic acid testing groups, formulate operable testing plans, and quickly organize and dispatch nucleic acid testing Testing force (including third-party testing agencies), do a good job in the organization and quality control of sampling testing. The scope of nucleic acid testing will be gradually expanded according to the circles of people involved in the epidemic area, people who have been to the epidemic area within 14 days, people in high-risk areas, and key groups in medium and low-risk areas. The classification adopts 1:1 single sample detection and 5:1, 10:1 mixed sample detection.
[Ninth Edition] Based on the epidemiological investigation and comprehensive judgment based on factors such as the size of the population in the area where the epidemic occurred, whether the source of infection is clear, whether there is a risk of community transmission, and whether the chain of transmission is clear, and based on the level of risk, the In principle, determine the scope, frequency and sequence of testing groups, formulate an operable nucleic acid testing plan, quickly organize and dispatch nucleic acid testing forces (including third-party testing institutions) and materials, and ensure the connection between "purchasing, delivery, inspection, and reporting" Smooth. Based on the risk assessment results, dynamically adjust the scope and frequency of nucleic acid testing to prevent the spread of the epidemic. When regional nucleic acid testing capabilities are insufficient, antigen testing can be used as a supplement to quickly coordinate and coordinate nucleic acid testing force support.

7. Strengthen prevention and control of key groups
[Eighth Edition] For people with high risk of exposure to the new coronavirus, high risk of transmission, and low resistance, it is necessary to strengthen health education and urge the implementation of wearing masks Follow daily protective measures such as hand hygiene, cough etiquette, etc., reduce participation in gathering activities, strengthen health monitoring, and accept nucleic acid testing and vaccination as required.
[Ninth Edition] Volunteers, community workers, , police, security guards and other professional groups with high risk of exposure should take personal protection based on the nature of their job, risk level or type of place they are in. Employees in high-risk positions must strictly implement closed-loop management, nucleic acid testing and control measures after closed-loop operations. After a local epidemic occurs in the county (district), try to avoid participating in gathering activities such as parties, dinners, weddings and funerals. The elderly, pregnant women, children, etc. with underlying diseases should avoid going out as much as possible and avoid going to crowded places, especially confined spaces with poor ventilation.
8. Strengthen prevention and control in key institutions
[Eighth Edition] After the outbreak, key institutions must further strengthen prevention and control measures according to local risk levels. Nursing homes, nursing homes, children's welfare homes and supervision places can adopt closed management and no halls are provided. Schools and childcare institutions can stop offline teaching due to measures such as eating and avoiding gatherings and mutual visits.
[Ninth Edition] Based on prevention and control needs, nursing homes, child welfare service institutions, nursing homes, mental health medical institutions and supervision places can implement closed management, video visits and other measures; colleges and universities can adopt closed management to reduce gatherings. Primary schools and daycare institutions can stop offline teaching; large enterprises and government institutions can adopt flexible working systems; construction companies of major construction projects can adopt measures such as closed management and reducing the number of staff in non-key positions.
