France was changed from a green to a yellow country in the update on Friday, although 9 of France’s 13 regions will remain green under the regional application of the traffic light system.

Like France, Belgium also switches from green to yellow. One Belgian region remains green.

Danish residents returning home from travel to a yellow country are required to take a Covid-19 test on their return to Denmark. Exceptions apply for people who are fully vaccinated or previously infected with the coronavirus.

Denmark classifies countries and regions around the world into four categories for Covid-19 travel restrictions: green, yellow, orange and red. The colour codes determine the rules that must be observed to enter Denmark, including those related to quarantine or isolation.

The requirements vary depending on whether you are travelling with a negative recent test, are fully vaccinated or have previously been infected with Covid-19. You can read more about the rules for each of the colour categories here and rules during isolation here.

An official list of the countries and regions which fall into each category is here. The list is usually updated on Fridays.

French capital Paris is among the regions to go yellow on Friday, as are the two regions encompassing the country’s Mediterranean coast as well as the island of Corsica.

The Belgian region to avoid switching to yellow is Wallonia, which stays green. Capital Brussels is now yellow.

Greece also sees more regions turn from yellow to green adding to the parts of the country which were changed last week. That means that most of Greece is now yellow.

No changes were made this week to the Danish foreign ministry’s guidelines for travel to the United Kingdom.

Since last week, England, Scotland and Northern Ireland have been red on the four-tier colour system for Covid-19 travel restrictions, while Wales is orange. Those colours will remain in place until at least July 31st.

That means the ministry still advises against all travel to all of the UK with the exception of Wales, which remains orange (all non-essential travel is discouraged).

As such, all travellers resident in England, Northern Ireland and Scotland will need to present a PCR test taken within the past 72 hours before boarding a plane to Denmark and will need to isolate upon arrival, even if previously vaccinated or infected.

Vaccinated people from Wales can still travel to Denmark without having to isolate.

Additionally, a worthy purpose is required to enter Denmark for all visitors from red countries. For orange countries, vaccinated people do not require a worthy purpose to enter Denmark, but people travelling on the basis of a recent negative test or prior infection do need a worthy purpose. It should be noted that the list of valid worthy purposes is shorter for red countries than for orange countries. You can read more about the specific rules and criteria for fulfilling a worthy purpose here.

The new travel guidelines come into effect at 4pm on Saturday, July 24th.
