Abstract

Abstract In light of the rapid growth of COVID-19 in mainland China, countries and regions outside of China have implemented travel restrictions of varying intensity. Using surveillance data of symptomatic travellers arriving from mainland China and detected in Singapore, this provides a proxy on the COVID-19 in mainland China. Furthermore, this allows us to ensure that travel-related restrictions commensurate with the current epidemiological situation and risk.
