From 11 March to 6 July 2020, a total of 268 imported cases of COVID-19 from abroad were confirmed in Guangzhou. 74% of the imported cases were detected during customs inspection and 19% under centralized quarantine. We advocate for legally enforced quarantine and monitoring of quarantined persons.
