This paper constructs an index system for evaluating the efficiency of COVID-19 sporadic outbreak prevention and control from three dimensions (epidemic prevention and control, epidemic traceability, and epidemic background) and with nine sub-indicators (pidemic duration, confirmed cases, detection route, mobile population management policy, flow investigation and tracing, nucleic acid detection, etc.) This evaluation index system is used to calculate and evaluate the control of epidemic in all the 32 regions of Chian since June 1, 2020 to June 1, 2021. Results show that there were significant differences in the efficiency of epidemic prevention and control among these regions, that the intensity of prevention and control measures did not match the severity of the epidemic, and that the management policies for mobile populations across regions lacked a unified yet scientific basis. Based on these, certain epidemic prevention and control management optimization suggestions are presented.
