摘　　要：After coronavirus disease 2019(COVID-19),previously known as pneumonia of unknown etiology(PUE)and 2019 novel coronavirus(2019-nCoV),was first discovered in Wuhan City,Hubei Province,the Chinese government took measures to stop the spread of the epidemic nationwide and interrupted local transmission in China(1–2).Although there have been several localized outbreaks that were caused by overseas importation of the virus—including Heilongjiang,Jilin,Beijing,Liaoning,and other provincial-level administrative divisions(PLADs)—these outbreaks have been stopped within two to four weeks and were limited in scope to less than ten cases or a few hundred cases for each event.With the COVID-19 pandemic still uncontrolled globally,the threat of importing the virus continues unabated and still threatens China’s population,virtually all of which is susceptible.
