Luxembourg is now classified as "green", following a steady decrease in coronavirus infections over the past weeks.
In the week between 14 and 20 June, the seven-day incidence rate per 100,000 inhabitants dropped from 30 to 14. The recent developments have led the European Centre for Disease Prevention and Control (ECDC) to classify the Grand Duchy as "green", i.e. as a country with a "low incidence rate", on its coronavirus map.
The EU introduced the map in October 2020. It allows residents to get an overview of the current coronavirus situation in Europe via this website.
In practical terms, a green classification means travel requirements to some destinations are more relaxed. To take one example, travellers arriving from areas classified as "green" can enter Croatia without being subject to any isolation, test, or vaccination requirement.
The EU provides more details on Covid-related travel requirements on the Re-open EU website.
