Impact of travel restrictions for travellers from China on the internal spread of SARS-CoV-2 in South Korea

J Travel Med. 2023 Sep 5;30(5):taad047. doi: 10.1093/jtm/taad047.

Abstract

South Korea implemented restrictions on travel from China in January of 2023. In this scenario-based model, we estimated that the travel restrictions for inbound travellers from China were associated with a 0.3–9.8% decrease in the internal spread of SARS-CoV-2 in South Korea (95% Confidence Interval, 0.2–11.7%).

Keywords: China; SARS-CoV-2; Travel restriction; screening; simulation; transmissibility; travel.
