1. Common criteria
Member States will take the following key criteria into account when considering to restrict free movement in response to the coronavirus pandemic:
the notification rate (the total number of newly notified COVID-19 cases per 100 000 population in the last 14 days at regional level)
the test positivity rate (the percentage of positive tests among all tests for COVID-19 infection carried out during the last week)
the testing rate (the number of tests for COVID-19 infection per 100 000 population carried out during the last week)
To ensure that comprehensive and comparable data is available, Member States will provide the European Centre for Disease Prevention and Control with the necessary data on a weekly basis.
2. A common map
Based on data provided by the Member States, the European Centre for Disease Prevention and Control will publish a map of EU Member States, broken down by regions, which will show the risk levels across the regions in Europe using a traffic light system. Regions will be indicated in the colours ‘green’, ‘orange’, ‘red’ and ‘grey’ (if not enough information is available).
This map will also include data from Iceland, Liechtenstein, and Norway.
In this map, an area should be marked in the following colours:
green, if the notification rate is less than 25 and the test positivity rate is less than 4%;
orange, if the notification rate is less than 50 but the test positivity rate is 4% or more, or, if the notification rate ranges from 25 to 150 but the test positivity rate is less than 4%;
red, if the notification rate is 50 or more and the test positivity rate is 4% or more, or if the notification rate is more than 150;
grey, if not sufficient information is available or if the testing rate is 300 or less.
The map will also provide travellers with general information as to the risk level at their destination. Together with the information made available on the ‘Re-open EU’ web platform, travellers should be able to tell whether they can expect to be subject to certain measures if they travel to another region in the EU.
