Study characteristics
Study design	Mathematical modelling study  Description: extended deterministic SEIR model SEIR model including quarantine compartment and additional pre‐infection seeding as influx into the exposed class to estimate daily infection counts over time under quarantine scenarios. Assumes that there is no ongoing community transmission at the destination and that there is no pre‐symptomatic infectiousness.
Disease	COVID‐19
Travel‐related control measure(s)	Quarantine of travellers All quarantined individuals were confined at home or to the university dormitory as per the current South Korean quarantine program for COVID‐19 (the model assessed scenarios with different rates of quarantine compliance: 70%, 80%, 90% or 100%) Date of implementation: 15 days before and after 1 March 2020
Country implementing the measure(s)	Country protected by the measure: South Korea Country restricted by the measure: China
Outcome(s)	Cases avoided due to the measure Outcome: total number of infected individuals seeded by arriving students Follow‐up: 180 days
