First, expand the scope of prevention and control areas. Based on the results of the flow investigation, we organized a transmission risk assessment and delineated prevention and control areas.
The second is to implement regional control. Adopt control measures such as suspension of work, suspension of business, and suspension of classes; adopt regional blockades to restrict the entry and exit of people. The blockade can be lifted when there are no new locally confirmed cases in the area 14 days after the last case is confirmed.
The third is to conduct a comprehensive investigation. Organize and carry out comprehensive household inspections. If any symptoms such as fever, dry cough, fatigue, diarrhea and other symptoms are found, they will be sent to designated medical institutions for investigation and treatment in a timely manner.
The fourth is to restrict crowd gathering activities. Restrict or stop markets, theater performances or other crowd gathering activities within a certain range, and close relevant places.
The fifth is to initiate emergency response at the corresponding level. Establish an emergency command and coordination mechanism to make preparations and deployments for medical treatment, laboratory testing, isolation management, etc.

3. Nucleic acid testing. According to the needs of epidemic prevention and control and testing capabilities, various localities can screen close contacts, overseas arrivals, fever outpatients, newly hospitalized patients and their accompanying personnel, medical institution staff, port quarantine and border inspection personnel, prison staff, and social welfare personnel. Key groups such as staff in elderly care institutions "should be tested as much as possible." Other groups of people practice "checking if they are willing to do so". Conduct timely random inspections of employees in farmers' markets, cold chain food processing and sales, catering, express delivery and other service industries.
4. Report. When medical and health institutions at all levels discover asymptomatic infections, they should report directly online within 2 hours. The onset date is the time of positive specimen collection, and the diagnosis date is the time of positive detection. If relevant symptoms or signs appear subsequently, it must be revised as a confirmed case within 24 hours, and the date of onset is revised to the time when the clinical symptoms or signs appear. After the centralized isolation medical observation is lifted, medical and health institutions must fill in the quarantine lifting date in the infectious disease report card of the online direct reporting system within 24 hours.
