Travellers entering France from 16 countries where the coronavirus is circulating widely now must undergo virus tests upon arrival at French airports and ports, AP reports.

French Prime Minister Jean Castex announced last month that the tests would be required starting August 1 for passengers France is allowing in from a list of approved countries unless they present proof of a negative test done within 72 hours of their departure.

Those who test positive in France as of Saturday must quarantine for 14 days.

France is not permitting general travel to and from the 16 countries, which include the United States and Brazil. The testing requirement therefore only applies to people entering under limited circumstances: French citizens who live in these countries or citizens of these countries with an established residence in France.
