Novel coronavirus Prevention and Control Plan (8th Edition) (Guo Wei Ming Dian [2021] No.248)
"novel coronavirus Prevention and Control Plan (Eighth Edition)" is a revised plan organized by the comprehensive group of joint prevention and control mechanism for novel coronavirus epidemic in the State Council on the basis of comprehensively summarizing the experience of prevention and control of normalized epidemic situation and local aggregation epidemic situation in China and combining the changes of national epidemic situation and research progress.
On May 11th, 2021, the State Council formulated "novel coronavirus Prevention and Control Plan (8th Edition)" in response to the comprehensive group of novel coronavirus epidemic prevention and control mechanism.
In order to guide all localities to do a good job in the normal prevention and control of the epidemic situation in novel coronavirus (hereinafter referred to as COVID-19, Covid-19), and fully implement the prevention and control strategy of "importing from outside and rebounding from inside", this plan is formulated on the basis of the first seven editions of the prevention and control plan according to the requirements of Class A management of Class B infectious diseases in COVID-19.
I. General requirements
Adhere to the principle of "putting prevention first, combining prevention with control, being scientific according to law, and classifying at different levels", adhere to the organic combination of normalized accurate prevention and control and local emergency response, and resolutely prevent the import of overseas epidemic situations and the rebound of domestic epidemic situations in accordance with the work requirements of "timely detection, rapid disposal, accurate control and effective treatment", and do our best to do a good job in normalized epidemic prevention and control. Implement the measures of "early prevention, early detection, early reporting, early isolation and early treatment", adhere to the principle of "prevention with people", strengthen epidemic prevention and control in key time periods, key areas and key populations, find sporadic cases and aggregated epidemics in time, and deal with the epidemic early, small, strict, real, scientific, accurate, powerful, orderly and effective, and put it out together when found, continuously consolidate the achievements of epidemic prevention and control, and earnestly
Second, the etiology and epidemiological characteristics
Novel coronavirus (2019-nCoV, hereinafter referred to as Covid-19) belongs to β coronavirus, which is sensitive to ultraviolet rays and heat. Fat solvents such as ether, 75% ethanol, chlorine-containing disinfectant, peracetic acid and chloroform can effectively inactivate the virus. People are generally susceptible. Based on the current epidemiological investigation and research results, the incubation period of COVID-19 is 1-14 days, mostly 3-7 days; The infectivity is relatively strong 1-2 days before onset and in the early stage of onset; The main sources of infection are confirmed cases and asymptomatic infected people in COVID-19; The main routes of transmission are respiratory droplets and close contact, and articles contaminated by virus can also cause infection. It is possible to spread through aerosols when exposed to high concentrations of aerosols in a relatively closed environment. As Covid-19 can be separated from feces and urine, it should be noted that its pollution to the environment may cause contact transmission or aerosol transmission. During the epidemic process in Covid-19, the genome is constantly mutating. At present, some mutated viruses have increased transmission power, but their potential pathogenicity and impact on vaccine efficacy need to be further studied.
Third, public measures
(1) Publicity and education.
Give full play to the role of new media such as Internet, Weibo, WeChat and client, and traditional media such as radio, television, newspapers and promotional materials, carry out publicity and education on prevention and control knowledge in COVID-19 in an all-round way, emphasize that everyone is the first responsible person for their own health, and advocate the masses to adhere to good hygiene habits and healthy lifestyles such as washing hands frequently, wearing masks, constant ventilation, public chopsticks system, "one-meter line" and cough etiquette, so as to improve residents’ awareness of self-protection and health literacy. Advocate residents to reduce the flow and gathering of people, advocate the new style of festival civilization, and do little weddings and funerals. Strengthen the training of epidemic prevention and control staff on COVID-19 prevention and control knowledge and strategic measures, eliminate panic, scientifically and accurately implement various prevention and control measures, and guide the public to develop conscious epidemic prevention behavior. For publicity and education, please refer to Annex 1 "Basic Code of Conduct for Citizen Epidemic Prevention".
(2) Vaccination.
1. Do a good job in vaccinating people aged 18 and above in key groups such as people with high risk of occupational exposure, people with risk of infection abroad, people who maintain normal social production and life operation, and key positions and occupations that maintain basic social operation, so as to provide them with health protection.
2. Do a good job in the vaccination of people aged 18 and above with high risk of disease transmission, such as students in key areas such as border crossings, service industries, labor-intensive industries, colleges and universities, faculty and staff of various schools, and vaccinate other people aged 18 and above who are willing to vaccinate, so as to reduce the risk of infection and morbidity.
3. According to the progress of vaccine research and development and the results of clinical trials, further improve the vaccination strategy.
(3) Patriotic health campaign. Adhere to prevention first, carry out patriotic health campaigns in depth, highlight key areas and weak links such as rural areas, urban-rural fringe areas and public gathering places, innovate ways and means, continuously promote urban and rural environmental improvement, and continuously improve public health facilities. Advocate a civilized, healthy and green lifestyle, popularize health knowledge, establish a good diet fashion, and promote civilized and healthy living habits. Promote the patriotic health campaign into communities, villages, families, schools, enterprises and institutions, promote the integration of health into all policies, and mobilize the masses to participate extensively in the patriotic health campaign.
Fourth, epidemic monitoring
(1) Report on the discovery of epidemic situation.
1. Case discovery report. All kinds of medical institutions at all levels should strengthen the monitoring of symptoms such as fever, dry cough, fatigue, sore throat, decreased sense of smell (taste), diarrhea, etc. Once suspicious patients such as fever are found, laboratory tests should be carried out in time, and the cases should be reported directly through the China Disease Prevention and Control Information System within 2 hours. Community health service stations, village clinics and individual clinics should report suspicious patients such as fever to community health service centers or township hospitals within 2 hours, and implement the nucleic acid detection strategy of "village report, township sampling and county detection" to find the epidemic situation as soon as possible. Strengthen the health monitoring of close contacts and close contacts (hereinafter referred to as close contacts), entry personnel, high-risk occupational groups, and key groups included in community management. Once the above symptoms appear, they should be sent to the hospital in time to carry out nucleic acid testing.
2. Report on finding asymptomatic infected persons. An asymptomatic infected person refers to a person who is positive in Covid-19’s pathogenic test but has no relevant clinical manifestations. It is mainly found through close contact and close contact, nucleic acid detection of key population such as entry personnel and high-risk occupational population, tracing of infection source, epidemiological investigation and crowd screening. The asymptomatic infected persons found should be reported directly through the China Disease Prevention and Control Information System within 2 hours, and transported to designated medical institutions for centralized isolation medical observation within 2 hours. If there are related symptoms or signs in the follow-up, it should be revised into a confirmed case within 24 hours.
3. Report on the discovery of clustering epidemic. Cluster epidemic refers to the discovery of 5 or more cases and asymptomatic infected persons in schools, residential quarters, factories, natural villages and medical institutions within 14 days. It is mainly found through routine diagnosis and treatment activities, data review and analysis of direct reporting of infectious diseases on the internet, epidemiological investigation of cases or asymptomatic infected people, health monitoring of personnel in key places and institutions and key populations. Aggregation epidemic situation should be reported on the network of management information system for public health emergencies within 2 hours.
(2) Multi-channel monitoring and early warning.
According to the principle of combining point with surface and combining infectious disease monitoring system with other departments’ monitoring systems, we will carry out multi-channel monitoring of people, things and environment.
1. Monitoring of medical personnel. Medical staff of all kinds of medical institutions at all levels, especially primary medical and health institutions, should raise their awareness of finding and reporting cases of COVID-19, and carry out Covid-19 nucleic acid detection for all patients with fever and other suspected patients without fever, cases of unexplained pneumonia and severe acute respiratory infection among hospitalized patients, and all newly admitted patients and their accompanying staff.
2. Monitoring of occupational groups at risk. Health monitoring and weekly full-time nucleic acid detection will be carried out for imported cold-chain food supervision and practitioners, centralized isolation site management and service personnel, direct contact personnel of imported goods at ports, medical staff of medical institutions designated for cases in COVID-19, medical staff of fever clinics and emergency departments of general medical institutions, employees of international transportation vehicles, ship pilots and other foreign ship operators, and frontline staff of immigration, customs and market supervision systems. Those who find symptoms such as fever, dry cough, fatigue, sore throat, decreased sense of smell (taste), diarrhea, etc. go to a medical institution with a fever clinic (consulting room) in time for nucleic acid detection.
Conduct weekly sampling nucleic acid testing for farmers’ markets, other departments of general medical institutions, express delivery, transportation and other specific service places and industry personnel.
3. Health monitoring of key populations. Do a good job in health monitoring for people from high-risk areas, medical observers who have been discharged from COVID-19, and immigrants who have been brought into community management. Those who find symptoms such as fever, dry cough, fatigue, sore throat, decreased sense of smell (taste), diarrhea, etc., go to a medical institution with a fever clinic in time and conduct nucleic acid detection.
4. Goods and environmental monitoring. To carry out sampling nucleic acid detection on imported cold chain food and its processing, transportation, storage and sales places; Sampling nucleic acid detection should be carried out for imported goods from high-risk countries and low-temperature transportation environment in land, sea and air ports, as well as their cargo holds, containers, carriages, containers and cargo storage places, and the detection frequency and sampling quantity can be increased under low temperature conditions in winter.
The environment of medical institutions with fever clinics and large-scale agricultural wholesale markets with cold chain food in cities are regularly tested for nucleic acids. Regularly carry out sewage monitoring in large-scale processing and processing places for imported frozen goods by sea.
5. Monitoring of key institutions. After one or more local confirmed cases or asymptomatic infected persons appear in this county (district), daily health monitoring shall be done for the personnel of key institutions such as pension welfare institutions, psychiatric hospitals, supervision places, personnel-intensive places (such as production workshops, shopping malls and supermarkets, training institutions), kindergartens and schools, and fever, dry cough, fatigue, sore throat, decreased sense of smell, diarrhea, etc. shall be found.
6. Centralized monitoring in isolated places. During the opening of centralized isolation places, environmental nucleic acid detection shall be carried out regularly.
7. Pathogen monitoring. The first or early cases in the local epidemic, key cases with epidemiological correlation with early cases, local cases with unknown infection sources, imported cases, imported articles and related environmental positive samples were sequenced and compared, so as to dynamically understand the variation of virus genes and find out the source of infection in time.
8. Analyze early warning. Strengthen information sharing among departments, carry out comprehensive analysis of epidemic monitoring and risk judgment, put forward risk assessment results and early warning response suggestions, and timely release epidemic information and health risk tips to the society.
For the requirements of multi-channel monitoring and early warning, please refer to Annex 2 Monitoring Plan of COVID-19.
See reference [2] for the full content.
First, improve the overall prevention and control requirements
We will improve the policies and measures for foreign defense, adhere to the principle of "people with the same defense", and strengthen the prevention and control of imported cold chain foods and articles. Emphasis is placed on strengthening epidemic prevention and control in key time periods, key areas and key populations to effectively prevent domestic epidemic rebound.
Second, strengthen organizational leadership
Local party committees and governments at all levels should improve the epidemic prevention and control command system and clarify the responsibilities and division of labor of departments. Establish command system startup mechanism, information reporting system, supervision and inspection system, emergency drill system, urban support system and other working mechanisms and systems. Improve information sharing and integration, and provide support for epidemic risk judgment, prevention and control measures formulation and overall resource allocation. According to different epidemic situations, reserve professional prevention and control personnel, nucleic acid detection ability, designated hospitals, centralized isolation places and epidemic prevention materials.
Third, strengthen work guidance
We will formulate and improve 12 working documents, including the basic code of conduct for citizens’ epidemic prevention, monitoring, epidemiological investigation, determination and management of close contacts, transfer of epidemic-related personnel, isolated medical observation, community prevention and control, disinfection, mental health services, sample collection and testing, prevention and control of imported epidemic situation, and prevention and control of epidemic situation in key links, and strengthen specific work guidance for different prevention and control fields and links.
Fourth, strengthen vaccination
Do a good job in vaccination of key groups such as people with high occupational exposure risk and risk of infection abroad, people who maintain normal social production and life operation, and key positions and occupations that maintain basic social operation; Do a good job in vaccination of people with high risk of disease transmission in key areas such as border ports and service industries to reduce the risk of infection and morbidity. According to the progress of vaccine research and development and the results of clinical trials, the vaccination strategy will be further improved.
V. Strengthening epidemic monitoring
Adhere to the monitoring of people, things and the environment, strengthen the monitoring of the epidemic situation of medical institutions, risk occupational groups, key groups and key institutions, and timely discover and report the epidemic situation. Strengthen pathogen monitoring, dynamically monitor virus variation, and understand the influence of virus variation on pathogen detection and vaccine protection.
Six, strengthen the prevention and control of epidemic situation in rural areas
Summarize the experience of dealing with cluster epidemic in rural areas, and strengthen targeted guidance and counterpart support for community prevention and control, epidemiological investigation, isolated medical observation, nucleic acid detection and disinfection in view of the objective situation that the ability of epidemic prevention and control in rural areas is relatively weak.
Seven, strengthen the isolation medical observation.
Strengthen the management of quarantine medical observation for entry personnel and close contacts, and require that nasopharyngeal swabs should be collected for nucleic acid detection during quarantine medical observation, and two samples of nasopharyngeal swabs should be collected at the same time when the quarantine is lifted, and different nucleic acid detection reagents should be used for detection respectively. In principle, the two tests should be carried out by different detection institutions. Carry out a nucleic acid test on the second day and the seventh day after the isolation. During this period, do a good job of health monitoring, reduce the flow, do personal protection when going out, and do not participate in gathering activities.
Eight, strengthen the precise management of secret connection.
It is stipulated that the nucleic acid detection of close contacts is negative on the first day and the fourth day during the isolation medical observation period, and the nucleic acid detection of close contacts on the first day, the fourth day and the seventh day is negative, which can relieve the centralized isolation medical observation. If the close contacts have positive nucleic acid detection on the first and fourth days, the close contact shall be managed according to the close contacts.
