According to relevant information, Xingyi flew to Dalian on June, 2020 10, and the connecting flight at Wan Fenglin Airport was not isolated. Because there is no epidemic situation, there is no need to quarantine at Feng Wan airport, but once there is an epidemic situation, arrangements should be made according to the local actual situation. In order to continuously consolidate the hard-won achievements of the city's epidemic prevention and control, and build a solid defense line for epidemic prevention and control, the COVID-19 Epidemic Prevention and Control Command decided to dynamically optimize and adjust the epidemic prevention and control measures, so that people returning from non-overseas, medium-and high-risk areas or local districts, cities and counties with epidemics do not need to be isolated.
