1, confirmed case. After the diagnosis, it should be transported to the designated medical institution or the receiving hospital within 2 hours. After the case is cured and discharged, it should be monitored at home for 7 days.
2. Suspected cases. If a suspected case is found, samples should be collected immediately for nucleic acid detection and review. During this period, one person should be isolated in a single room, and the COVID-19 nucleic acid test is negative for two consecutive times (the sampling time is at least 24 hours apart), so that the diagnosis of suspected cases can be ruled out.
3. Asymptomatic infected persons. According to the management of mild cases, centralized isolation medical observation was conducted in Fangcang Hospital for 7 days, during which nasopharyngeal swabs were collected for nucleic acid detection on the 6th and 7th days (the sampling interval was at least 24 hours). If the Ct values of N gene and ORF gene are both ≥35 (the limit of fluorescence quantitative PCR detection method is 40, the same below), or the detection is negative (the limit of fluorescence quantitative PCR detection method is lower than 35, the same below), it is acceptable.
If the above conditions are not met, they will continue to be isolated in the shelter hospital until they meet the criteria for leaving the cabin. During the period of centralized isolation medical observation, the patient's condition should be well monitored, and after reaching the diagnostic standard of confirmed cases, it should be corrected as confirmed cases in time. After the centralized isolation medical observation is lifted, home health monitoring should continue for 7 days.
4, after discharge (cabin) nucleic acid test positive personnel. After the previous infected person was discharged from the hospital (cabin), the nucleic acid test of respiratory tract samples was positive. If there are no symptoms and signs and the Ct value of nucleic acid detection is ≥35, the close contacts will no longer be managed and judged; If the Ct value of nucleic acid detection is less than 35, the risk of transmission should be quickly evaluated by combining the course of disease and the dynamic change of Ct value. There is a risk of transmission, according to the management of infected people, to judge and control their close contacts who live together or often work, not to judge close contacts.
If there is no risk of transmission, it is judged that there are no managers and close contacts. If there are clinical manifestations such as fever and cough, or CT images show that lung lesions are aggravated, they should be immediately transported to designated medical institutions for classified management and treatment according to the condition. If the Ct value of nucleic acid detection is ≥35, it is not necessary to track and control the close contacts.
If the Ct value of nucleic acid detection is less than 35, close contacts who live and work with them, etc. It should be judged and controlled, and close contacts do not have to judge.
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 combination of normalized precise 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".
Adhere to scientific and accurate prevention and control, implement the measures of "early prevention, early detection, early reporting, early isolation and early treatment", further strengthen source control, adhere to the prevention of people, things and the environment, strengthen the prevention and control of epidemic situations in key time periods, key regions and key populations, improve the sensitivity of monitoring and early warning, and find sporadic cases and aggregated epidemics in time.
Effectively, orderly and forcefully respond to the epidemic situation, put it out together, control the epidemic situation to a minimum in the shortest time and at the lowest cost, earnestly safeguard people's life safety and health, and coordinate the epidemic prevention and control with economic and social development to the maximum extent.
