On the 28th, the comprehensive group of the joint prevention and control mechanism of the State Council released the prevention and control plan for novel coronavirus pneumonia (Ninth Edition).
Leizhenglong, deputy director of the Bureau of disease control and prevention of the National Health Commission and a first-class inspector, introduced that the ninth edition of the plan mainly has three changes – optimizing and adjusting the isolation management period and methods of risk personnel, unifying the delimitation standards of closed control areas and medium and high risk areas, and improving the requirements related to epidemic surveillance. The change “is not to relax the prevention and control, but to require more standardized, accurate and faster”.
What are the details of the new version of the plan?

1. the average incubation period of virus is shortened
? Eighth Edition ? the incubation period of COVID-19 is 1-14 days, mostly 3-7 days; The infectivity was relatively strong 1-2 days before and at the initial stage of the disease.
[9th Edition] the average incubation period of Omicron mutant is shortened, mostly 2-4 days. It has stronger transmission ability, faster transmission speed, lower infection dose, weakened pathogenicity and stronger immune escape ability.
2. expansion of vaccination population
[the Eighth Edition] we will do a good job in the vaccination of people aged 18 and above among the population with high occupational exposure risk, the population at risk of overseas infection, the personnel who maintain the normal production and living operation of the society, the occupations in key positions that maintain the basic operation of the society, key areas such as border ports, service industries, labor-intensive industries, college students and teaching staff of various schools, and other key populations, Vaccinate other people aged 18 and above who are willing to vaccinate.
[9th Edition] the scope of vaccination against novel coronavirus was expanded to people over 3 years old. The principle of informed consent and voluntariness was adhered to, and people over 3 years old without vaccination taboos were encouraged to receive it. The eligible target population over 18 years old shall receive one dose of secondary homologous or sequential enhanced immunization. Homologous enhanced immunization and sequential enhanced immunization shall not be accepted at the same time. Focus on improving the whole process vaccination rate and enhanced immunization coverage rate of the elderly aged 60 and above and other high-risk groups of severe diseases.

3. adjustment of management mode of close contacts
[8th Edition] the close contacts shall be subject to 14 days’ centralized isolation medical observation, and nucleic acid detection shall be conducted on the 1st, 4th, 7th and 14th days of centralized isolation medical observation. After the release of isolation, carry out 7-day home health monitoring. During this period, do a good job in monitoring body temperature and symptoms to reduce mobility. When going out, do a good job in personal protection, do not participate in gathering activities, and carry out nucleic acid testing on the second day and the seventh day respectively.
[version 9] the management measures of “7-day centralized isolation medical observation +3-day home health monitoring” shall be taken for close contacts. They shall not go out during home health monitoring. If they have to go out for medical treatment and other special circumstances, they shall take personal protection and try to avoid taking public transport. Nucleic acid detection shall be carried out on the first, second, third, fifth and seventh days of centralized isolation medical observation, and on the third day of home health monitoring. In case of a large-scale epidemic, in order to alleviate the serious shortage of resources in the centralized isolation points, the measures of “5-day centralized isolation medical observation +5-day home isolation medical observation” can be taken for close contacts. Nucleic acid testing shall be carried out once in the first, second, third and fifth days of centralized isolation medical observation, and once in the second and fifth days of home isolation medical observation. The isolation management period shall be calculated from the last exposure. After the centralized isolation is removed, it shall be returned to the residence in a “point-to-point” closed loop.
4. adjustment of control mode for inbound personnel
[Eighth Edition] implement 14 day isolation medical observation measures for inbound personnel. The “7+7” isolation medical observation measures can be implemented on a voluntary basis for inbound personnel who have completed remote nucleic acid testing (only those who have a history of vaccination need to have negative nucleic acid testing) and who have closed transfer management conditions, home isolation conditions (with independent rooms and toilets) and can carry out precise community control. After the release of isolation, carry out 7-day home health monitoring. During this period, do a good job in monitoring body temperature and symptoms to reduce mobility. When going out, do a good job in personal protection, do not participate in gathering activities, and carry out nucleic acid testing on the second day and the seventh day respectively.
[version 9] the management measures of “7-day centralized isolation medical observation +3-day home health monitoring” were implemented for inbound personnel. Nucleic acid detection was carried out on the first, second, third, fifth and seventh days of centralized isolation medical observation, and on the third day of home health monitoring. Do not go out during home health monitoring. If it is necessary to go out for medical treatment and other special circumstances, do a good job in personal protection, and try to avoid taking public transport.

5. unified use of medium and high risk area delimitation and control scheme
The ninth edition of the plan connects the delineation standards and prevention and control measures of the two types of risk areas, and unifies the concept of medium and high risk areas to form a new risk area delineation and control plan:
After the occurrence of the local epidemic, the high, medium and low risk areas shall be defined according to the activity track of the cases and asymptomatic infected persons and the risk of epidemic transmission. Areas such as places of residence of cases and asymptomatic infected persons, as well as places of work and activities where activities are frequent and the risk of epidemic spread is high, are classified as high-risk areas, and “door-to-door service at home” is implemented; Areas where cases and asymptomatic infected persons stay and move for a certain period of time and may have the risk of epidemic spread are classified as medium risk areas, and “people can’t leave the area and pick up things at different peaks”; Other areas in the counties (cities, districts and banners) where the medium and high-risk areas are located are low-risk areas, and “personal protection and avoiding aggregation” are implemented. Personnel in the low-risk areas shall hold the negative certificate of nucleic acid test for 48 hours when leaving the city.
6. Optimize regional nucleic acid detection strategy
[Eighth Edition] according to the epidemic situation and epidemiological investigation results, carry out risk assessment, determine the scope and priority of nucleic acid testing population, formulate operational testing plans, quickly organize and dispatch nucleic acid testing forces (including third-party testing institutions), and do a good job in the organization and quality control of sampling and testing. According to the people in epidemic areas, the detection range of nucleic acid should be gradually expanded for those who have been to epidemic areas within 14 days, those in high-risk areas, and key populations in low – and middle-risk areas. 1:1 single sample test and 5:1 and 10:1 mixed sample test are adopted for classification.
[9th Edition] on the basis of epidemiological investigation, the scope, frequency and sequence of the detection population are determined according to the size of the population in the epidemic area, whether the source of infection is clear, whether there is community transmission risk and whether the transmission chain is clear, and the operable nucleic acid detection scheme is formulated according to the risk and the principle of classification, Quickly organize and dispatch nucleic acid testing forces (including third-party testing institutions) and materials to ensure smooth connection of “procurement, delivery, inspection and reporting”. Based on the results of risk assessment, dynamically adjust the scope and frequency of nucleic acid detection to prevent the spread of the epidemic. When the regional nucleic acid detection capability is insufficient, antigen detection can be used as a supplement to quickly coordinate the support of nucleic acid detection forces.

7. strengthen prevention and control of key groups
[8th Edition] for people with high exposure risk, high transmission risk and low resistance to novel coronavirus, it is necessary to strengthen health education, urge the implementation of daily protective measures such as wearing masks, hand hygiene and cough etiquette, reduce participation in gathering activities, strengthen health monitoring, and receive nucleic acid testing and vaccination as required.
[9th Edition] volunteers, community workers, police, security guards and other occupational groups with high exposure risk should do a good job of personal protection in combination with their own job nature, risk level or type of place. Employees in high-risk positions shall strictly implement closed-loop management, nucleic acid detection and control measures after closed-loop operation. After the local epidemic occurs in the county (District), try to avoid attending gatherings, dinners, weddings, funerals and other gatherings. The elderly, pregnant women and children suffering from basic diseases shall go out as little as possible, and avoid going to densely populated, especially poorly ventilated, confined spaces.
8. strengthen prevention and control of key institutions
[8th Edition] after the outbreak, key institutions should further strengthen prevention and control measures according to the local risk level. Nursing homes, nursing homes, children’s welfare homes and regulatory places can adopt closed management, do not provide food in the classroom, avoid gathering and mutual visits, and schools and nurseries and kindergartens can stop offline teaching.
[9th Edition] according to the needs of prevention and control, nursing homes, service institutions in the field of child welfare, nursing homes, mental health medical institutions and regulatory places can implement closed management, video visits and other measures; Colleges and universities can adopt closed management to reduce aggregation, and offline teaching can be stopped in primary and secondary schools and kindergartens; Large enterprises, government agencies and institutions can adopt flexible working system; Construction enterprises of major construction projects can adopt closed management and reduce the number of staff in non key positions.
