Although the epidemic has ended now, we can't relax our vigilance, but we should pay attention to the prevention of public places. In order to further do a good job in prevention and control, fully implement prevention and control, and safeguard people's life safety, China has issued a prevention and control plan for novel coronavirus. Details are as follows. General requirements

Clearly adhere to the principles of putting prevention first, combining prevention and control, and scientific prevention and control according to law, implement the "four early" measures in accordance with the work requirements of timely detection, rapid disposal, accurate control and effective treatment, and resolutely prevent the import of overseas epidemic situations and the rebound of domestic epidemic situations. Etiology and epidemiological characteristics

It is emphasized that the main transmission routes are still respiratory droplets and close contact transmission, but contact transmission or aerosol transmission can be caused by exposure to virus-contaminated articles and virus-contaminated environment under certain conditions. Epidemic monitoring

First, according to the epidemic changes at home and abroad, the history of case epidemiology emphasizes reporting the travel history or residence history of cases or asymptomatic infected communities, and the contact history of cases or asymptomatic infected people, which is more accurate and scientific. Second, it is emphasized that asymptomatic infected people are respiratory tract and other specimens with positive novel coronavirus pathogen test, without relevant clinical manifestations, such as fever, dry cough, sore throat and other symptoms and signs that can be perceived by themselves or recognized clinically, and CT imaging has no COVID-19 imaging characteristics. The third is to increase multi-channel monitoring and early warning. It is required to carry out monitoring work for people and the environment in accordance with the principles of combining point with surface, combining infectious disease monitoring system with other departments' monitoring systems, and combining routine monitoring with enhanced monitoring. The fourth is to improve the definition of clustering epidemic, and according to the zoning and grading standards, the clustering epidemic will be revised from "2 cases and above" to "5 cases and above". Epidemiological investigation

The definitions of imported cases, imported secondary cases and close contacts (close contacts for short) are added, and it is emphasized to do a good job in case investigation, close contact judgment, case active search, cluster epidemic investigation and investigation information report, and to do a good job in analyzing the source of infection, pollution scope, transmission characteristics and transmission chain. Close contacts and secret connection management

First, increase the secret connection management requirements of secret connection, including management methods, management processes, management requirements and information reports. The second is to increase the requirements for nucleic acid detection during centralized isolation medical observation, requiring close contacts and close-knit centralized isolation medical observation to carry out nucleic acid detection for 3 times and 1 times respectively. The third is to refine the requirements of centralized isolation and home medical observation, formulate guidelines for centralized isolation and home medical observation, and guide local governments to carry out relevant work scientifically. Epidemic situation disposal

First, aiming at low, medium and high risk areas, further refine the prevention and control measures, implement normalized prevention and control work in low risk areas, and strengthen epidemic situation monitoring and response preparation. Second, scientifically delimit the scope of prevention and control areas in medium-risk areas to the smallest unit (for example, schools take classes, buildings as units, factories take workshops, workplaces as offices, and rural households as the smallest units), and start intensive monitoring and implement terminal disinfection. According to the needs of epidemic prevention and control and the risk of infection, the scope and priority of nucleic acid detection population are determined. Third, in high-risk areas, schools, buildings, factories, workplaces and natural villages are the smallest units to delimit prevention and control areas, and measures such as comprehensive household investigation, restricting crowd gathering activities and regional control are carried out to start emergency response. Specimen collection and laboratory testing

The content of gene sequencing is added, which requires that the first case with unknown source of infection and positive samples found in environmental monitoring should be traced back to the source. Prevention and control of epidemic situation abroad

Adjust the "7+7" and "2+1" centralized isolation medical observation measures. After receiving the customs nucleic acid test at the port of entry, the entry personnel will be quarantined for 7 days at the place of entry and will be tested for nucleic acid at their own expense (in principle, on the fifth day after entering the centralized isolation medical observation point). Those with negative test results can be quarantined at home for 7 days, and will be voluntarily tested for 1 times at their own expense after the quarantine expires for 14 days. Prevention and control of key links

Increase the prevention and control requirements of cold chain food processing and trading places, and reduce the risk of epidemic spread in cold chain links. Social health management and services

Strengthen community prevention and control and services, patriotic health campaign, publicity and education and risk communication, personal hygiene and protection, mental health services and other measures. Setting of isolation sites

On the premise of keeping other requirements for setting isolation sites basically unchanged, the site selection requirement is modified to "be relatively independent and keep a certain protective distance from densely populated residential and activity areas", which is conducive to improving the overall isolation capacity of the city on the basis of ensuring isolation safety and avoiding epidemic spread.

The prevention and control plan requires all localities to further consolidate the "four parties" responsibilities of territories, departments, units and individuals, strengthen joint prevention and control, strengthen capacity building, conduct regular judgments and risk assessments on the epidemic situation within their respective jurisdictions, organize prevention and control skills training and actual combat drills, strengthen guidance and inspection on prevention and control work in key areas, key places and key populations, and urge the implementation of various prevention and control measures.
