Meanwhile, Italian and Greek islands have been moved back to the yellow zone.

The islands of Rhodes and Santorini are moving from the red into the yellow zone, and the Portuguese island of Madeira is moving from the green zone to the yellow one. And France's Reunion is also moving into the green zone.

Self-isolation and testing requirements remain unchanged. Travelers from the red area who have not been vaccinated and who have no record of past infection will be required to have a pre-travel test and to self-isolate for 10 days after the arrival. Travelers from the yellow area are required to take a pre-travel test and to repeat it on 3-5th day of arrival, but they are not required to self-isolate for 10 days.

Travelers from the green area are only required to complete the NVSC registration form (as are those arriving from the red and yellow areas) and take a pre-travel COVID-19 test.
