Estimated relative change in risk of SARS-CoV-2 importation under the hypothetical scenario that travel restrictions had been introduced, but only 25% or 50% of flights had been cancelled

Notes: In the main text, this scenario is referred to as hypothetical scenario 2. The original assumption was 75% of flights had been cancelled. Positive change in relative risk (green) equals lower risk of virus importation.
