General guidance from the Danish Health Authorities to prevent infection

The Danish Health Authority recommends vaccination because it protects you from becoming infected and ill from COVID-19. The more people get vaccinated, the better control we have over the epidemic.

Remember that it is important to get both the 1st and 2nd vaccine dose to get the full protection of the vaccines from Pfizer-BioNTech and Moderna. A 3rd dose is recommended for people above 18 years. 

If you have symptoms of COVID-19, you should self-isolate and take a PCR test. If your test is positive, you must remain in self-isolation - even if you have been vaccinated. 

To self-isolate means:

  • To stay at home and not have contact with anyone else other than the people you live with.
  • To avoid close physical contact with other members of your household.
  • To pay particular attention to hygiene and cleaning.

If you test positive for novel coronavirus or are a close contact of someone who is infected but are unable to self-isolate at home - for example, if your home is very small or if you live with someone who is at higher risk of severe illness from COVID-19 - then your local municipality might offer you an out-of-home stay at a suitable facility. 

Please call your municipality to learn more about your options.

COVID-19 infection can occur by spreading droplets in the immediate environment. By keeping your distance and limiting close and physical contact, you can therefore avoid infection.

Therefore, keep your distance from others in the public space whenever it is possible.

As the majority of the Danish population is vaccinated, you can once again shake hands and give hugs to your friends and family. However, be aware of people who are at higher risk of developing serious illness from COVID-19, especially if they or you have not been vaccinated.

Airing out effectively prevents droplet spread indoors.

When someone e.g. coughs or sneezes most droplets fall to the ground within a few metres. Most of these droplets fall to the ground within a few metres, but the most minute droplets - the so-called microdroplets - can remain suspended in the air for some time which is why the risk of infection is higher indoors and when many people are gathered in small spaces for longer periods of time. 

Microdroplets accumulate in enclosed spaces with poor ventilation. Therefore, you can prevent the spread of infection and reduce the concentration of airborne microdroplets by ventilation and creating a cross draft by opening windows and doors.

How to air out effectively

If you do not have a ventilation system in your home, you can increase ventilation by:

  • Creating a cross draft by opening windows and doors.
  • Opening windows and doors for 5-10 minutes 4-5 times a day.
  • Airing out more often if several people are gathered indoors, for example, before and after you have had guests in your home.
  • Creating a draft every hour if you are together for an extended period of time.

Proper hand hygiene is the most effective way to prevent contact spread. 

Washing your hands or using and hand sanitiser is equally effective. However, hand sanitisers only work properly when your hands are dry and not visibly dirty, so you should always wash your hands if they are visibly dirty or wet, after toilet visits or changing nappies, and before you handle food. Please remember to help children maintain good hand hygiene.

The risk of contact spread increases dramatically when you touch contact point and surfaces that are touched by many people, for example as door handles, hand rails, light switches, keyboards, computer mice, armrests, the edges of tables, toys, tools, utensils, taps, toilets, etc.

Clean contact point frequently and thoroughly using ordinary cleaning products and disinfectants.

Test for COVID-19

Get tested when you have symptoms or are a close contact

In order to prevent the spread of infection, it is important that you take a PCR test when you have symptoms of COVID-19 or are a close contact of someone who has tested positive.


If you are infected with coronavirus

If you are infected with coronavirus, you are encouraged to self-isolate as soon as possible and contact the Danish Patient Safety Authority’s contact tracing hotline, Coronaopsporing, who can help you identify and notify close contacts.


Where you need to show a corona passport

A corona passport is proof that you have either been vaccinated against or have previously been infected with COVID-19, or have tested negative within the past 72 hours (PCR test) or 48 hours (rapid antigen test).
