The green category is the best in the epidemiological situation of the ECDC map, which combines the notification rates of Covid-19 cases over the last 14 days, the number of tests performed and the total positives, which are updated weekly.

Mainland Portugal and Madeira remain in the orange category (territories where the notification rate of new infections is 50 to 75 per 100,000 inhabitants in the last 14 days and the test positivity rate is 1% or between 75 and 200 new infections per 100,000 population and test positivity rate of 4% or more), which means 'moderate risk'.

The Azores – in green – have less than 50 new cases and a positivity rate of less than 4%, or less than 75 cases, but with a positivity rate of less than 1%.

These maps from the European agency follow a system of traffic lights on the spread of covid-19 in the EU, starting with green (favourable situation), passing through orange, red and dark red (very dangerous situation) and serve as a guide for the member States to decide on the restrictions to apply to travel within the Community space.

In mid-June, the EU Council adopted a recommendation for a coordinated approach to travel, proposing that vaccinated people and those recovered from covid-19 should not be subjected to restrictive measures such as quarantines or testing.
