What are international travel-related control measures?

 International travel control measures are methods to manage international travel to contain the spread of COVID-19. Measures include:

• closing international borders to stop travellers crossing from one country to another;
• restricting travel to and from certain countries, particularly those with high infection levels;
• screening or testing travellers entering or leaving a country if they have symptoms or have been in contact with an infected person;
• quarantining newly arrived travellers from another country, that is, requiring travellers to stay at home or in a specific place for a certain time.
