文摘BACKGROUND Since the release of Protocol for Prevention and Control of COVID-19(Edition 7),coronavirus disease 2019(COVID-19)control and prevention has been facing new challenges in China with evolving domestic and global epidemiological situations.Since September 2020,China has experienced more than 20 local outbreak waves,all of which were able to be contained within a few weeks.
