As of 1 February 2022, Denmark is removing its COVID-19 restrictions. From that day onwards, there will no longer be limitations on e.g., the number of people that can gather at any kind of business event, no mandatory masks, and no COVID-19 passport requirements - but people are still encouraged to remember good habits.
COVID-19 has been declared a non-critical disease in Denmark based on a combination of low hospitalization numbers and high vaccination numbers.
With the easing, the rules for entry into Denmark also change, but there are still some travel entry rules for foreigners arriving in Denmark in place. If you are not fully vaccinated or immune e.g., you must still present a recent negative test result.
