Estimated relative change in risk of SARS-CoV-2 importation under the hypothetical scenario that travel restrictions also had been introduced in the 10 high-passenger-volume airports

Notes: In addition to the travel restrictions introduced in the 80 countries listed in Table 1, we assumed that travel restrictions had also been introduced in the 10 highest-passenger-volume airports not included in Table 1. That is, Brussels (Belgium); Lester B. Pearson International, Toronto (Canada); Baiyun, Beijing and Shanghai (China); Dublin International (Ireland); Schipol, Amsterdam (Netherlands); Barajas, Madrid and Aeropuerto El Prat de Barcelona (Spain); Suvarnabhumi Bangkok International, Bangkok (Thailand). Positive change in relative risk (green) equals lower risk of virus importation.
