What are the three days of seven days and three inspections?

"Three inspections in seven days" are the first day, the third day and the seventh day respectively, which are generally applicable to people with yellow codes and those who receive SMS prompts.

Nucleic acid detection three times in seven days means that three times of nucleic acid detection are completed within seven days, and the time of these three times of nucleic acid detection is 1, 3 and 7 days respectively. If COVID-19 is infected, there is still a certain incubation period. According to the current data, the average incubation period in COVID-19 is about 3-4 days. If the nucleic acid is detected only 3 days ago, it may be undetectable, leading to missed diagnosis and misdiagnosis. Therefore, in order to ensure this,

Adjust the control time of close contacts and entry personnel from "14 days of centralized isolation medical observation +7 days of home health monitoring" to "7 days of centralized isolation medical observation +3 days of home health monitoring", take nucleic acid detection measures for "1, 4, 7 and 14 days of centralized isolation medical observation" and collect nasopharyngeal swabs. The control measures of close contact were changed from "7-day centralized isolation medical observation" to "7-day home isolation medical observation", and nucleic acid detection was carried out on 1, 4 and 7 days.

Within 7 days, the following personnel will be given a yellow code.

1, the time and space of confirmed cases or asymptomatic infections intersect.

2. People who have lived in cities and counties where high-risk areas are located or potential communities to spread risks.

3. People who have lived in the city and state where the moderately dangerous area is located.

4, the occurrence of local epidemic may lead to long-term spread in the province.

5 nucleic acid testing should be carried out regularly in the province according to the relevant requirements, and the yellow code should be given if it is not tested within the time limit.

Novel coronavirus Prevention and Control Plan (9th Edition)

1. Epidemiological investigation. After the outbreak, according to the principle of territorial management, the special class (working group) established by the joint prevention and control mechanism of the city where the medical and health institution reporting the case is located will carry out epidemiological investigation. The field epidemiological team composed of health, disease control, public security and other departments carried out their work according to the division of work, and adopted the method of combining field and telephone epidemiology. The positive personnel arrive at the scene within 2 hours after re-confirmation, complete the investigation of the core information of the case within 4 hours, complete the preliminary epidemiological investigation report within 24 hours, and update the epidemiological report dynamically according to the progress of the epidemic. The content and focus of epidemiological investigation should be dynamically adjusted according to the progress and scale of the epidemic. For early detection, few cases and no continuous spread in the community, it is necessary to quickly carry out accurate epidemiological investigation, conduct detailed investigation on the past contact history and activity trajectory of the cases, clarify the source of infection of the cases, determine close contacts, close contacts, exposed personnel in epidemic-related places and other risk personnel, and delineate risk areas. When the epidemic situation develops further, the number of cases increases obviously, and the community continues to spread, so it is difficult to clarify the transmission chain. In addition, the community has been designated as a medium-high risk area to implement closed control measures management, and the focus of epidemiological investigation has been adjusted to grasp the basic information of the case, the onset time, and the positive time of the first nucleic acid test. , close contact tracking and epidemic analysis. For key cases, such as those infected by uncontrolled personnel such as material support personnel, couriers, volunteers and community service personnel, and new infected people in the final stage of effective control of the epidemic, detailed and accurate investigations should be conducted.

2. Identification and management of close contacts and other risk personnel. According to the case action trajectory and epidemiological information, with the support of "three public (industrial)" collaborative multi-sector technical means and big data information, public health professionals can quickly and accurately determine close contacts, close contacts and exposed personnel in epidemic-related places. Give priority to identifying and managing close contacts with high risk of infection, such as frequent contact with cases and long duration. For crowded and complicated cases (such as restaurants, entertainment places, supermarkets and other closed space places), the scope of judging close contacts can be appropriately expanded. Close contacts shall take the management measures of "7 days of centralized isolation medical observation +3 days of home health monitoring" (hereinafter referred to as "7+3" management measures), and shall not go out during home health monitoring. If you need to go out due to special circumstances such as medical treatment, you should do a good job of personal protection and try to avoid taking public transport. On 1, 2, 3, 5 and 7, the nucleic acid was detected on the day of centralized isolation medical observation, and on the third day of home health monitoring. When a large-scale epidemic occurs, in order to alleviate the serious shortage of resources in centralized isolation points, close contacts can take the measures of "centralized isolation medical observation for 5 days+home isolation medical observation for 5 days", and carry out nucleic acid detection on 65438+ centralized isolation medical observation for 0, 2, 3 and 5 days, and carry out nucleic acid detection on home isolation medical observation for 2 and 5 days. The isolation management period starts from the last exposure, and returns to the place of residence in a "point-to-point" closed loop after the centralized isolation is lifted. Long-term close contacts, such as living, eating, working (studying) and entertainment (such as chess and cards, karaoke) with close contacts with high risk of infection, are judged as close contacts. Close contacts were observed at home for 7 days, their body temperature and symptoms were monitored every day, and their nucleic acids were detected on 1, 4 and 7 days respectively. If the nucleic acid test of close contacts is negative during the period of home isolation medical observation, and the previous two times corresponding to close contacts are negative during the period of isolation medical observation, the home isolation medical observation can be lifted on the seventh day; If the results of the first two nucleic acid tests of close contacts are positive, close contacts will be adjusted to close contacts and managed as close contacts. If people are exposed in epidemic-related places such as wedding (funeral) banquets, restaurants, supermarkets, shopping malls and farmers' markets that are in contact with suspected cases, confirmed cases and asymptomatic infected people, but they do not meet the principle of close contacts and close contacts, nucleic acid detection measures shall be taken for people with high risk of infection after risk assessment.

3. Division and prevention of risk areas. After the occurrence of local epidemic, according to the trajectory of cases and asymptomatic infected persons and the risk of epidemic spread, high, medium and low risk areas are delineated. Areas where cases and asymptomatic infected people live, as well as workplaces and activities with frequent activities and high risk of epidemic spread, are classified as high-risk areas. In principle, high-risk areas are defined by residential quarters (villages), and the scope of risk areas can be adjusted according to the results of traffic survey and judgment, and measures such as "staying at home and providing on-site services" can be adopted. The high-risk area was reduced to the medium-risk area for 7 consecutive days, and the medium-risk area was reduced to the low-risk area for 3 consecutive days. Areas where cases such as workplaces and activity places and asymptomatic infected people stay and flow for a certain period of time and may have the risk of epidemic spread are classified as medium-risk areas, and the scope of risk areas is defined according to the results of mobile investigation and judgment. Control measures such as "people don't leave the area, taking things at different peaks" were taken in the middle-risk area, and no new infections were reduced to the low-risk area for 7 consecutive days. Other areas in the counties (cities, districts and banners) where the middle and high-risk areas are located are low-risk areas, and preventive measures such as "personal protection and avoiding gathering" should be taken. People in low-risk areas should have a negative certificate of 48-hour nucleic acid test when they leave their city. After all the high-risk areas are removed, all counties (cities, districts and banners) will implement normalized prevention and control measures. In the process of epidemic disposal, if the risk of individual cases and asymptomatic infected people spreading to their residence, workplace and activity area is low, and close contacts have been controlled in time, and it is judged that there is no risk of community transmission, the risk area may not be delineated.

4. Investigation and control of risk personnel. When it is found that infected people, close contacts, close contacts, people exposed in epidemic-related places and people in middle and high-risk areas flow out of the local area, the local joint prevention and control institution shall send an investigation form (including information needed for investigation and control, such as identity information, contact number, contact information and last exposure time) to the inflow place through the national epidemic prevention and control management platform or letter within 2 hours, or timely send cross-regional investigation through the established "point-to-point" cross-regional investigation mechanism between cities. After receiving the investigation information, the investigation team will quickly investigate the relevant personnel, and take control measures such as sending short messages, nucleic acid detection, health monitoring and isolation according to the risk level, to ensure that the control measures for each risk person are in place, and feed back the preliminary investigation control results to the epidemic area within 24 hours after receiving the investigation information, forming an information closed loop. Non-epidemic areas should also take the initiative to investigate the influx of people in high-risk areas to prevent the spread of the epidemic. For those who have lived in high-risk areas for 7 days, they were isolated for 7 days for medical observation, and for those who were isolated for 1, 2, 3, 5 and 7 days for nucleic acid detection. Those who have lived in a moderately dangerous area for 7 days were observed at home for 7 days, and their nucleic acids were detected at 1, 4 and 7 days respectively. Do not have the conditions for home isolation medical observation, take centralized isolation medical observation; The management period starts from leaving the risk area. For those who have lived in low-risk areas for 7 days, they should complete nucleic acid detection twice within 3 days and do a good job in health monitoring. Measures for the administration of overflow personnel in high-risk areas within the jurisdiction of provinces (autonomous regions and municipalities directly under the Central Government) shall be formulated and promulgated by local governments.
