Prevent infection

To limit the spread of covid-19, it is important to follow the rules and recommendations set by the authorities.

Updated: 27 April 2022

It is important to follow the Danish Health Authority’s six steps for infection prevention. Please be mindful of them at home, in public spaces, in school and at the workplace.

General guidance from the Danish Health Authorities to prevent infection

Vaccination is the most effective measure against covid-19 and a high adherence to vaccination is a crucial element in epidemic management.

Despite the low infection pressure, the Danish Health Authority still recommends that some groups be vaccinated to protect against serious illness and death.

This applies to people at particularly increased risk of a serious course of covid-19 disease, especially people over the age of 40 and to pregnant women if they are unvaccinated.

The Danish Health Authority continues to recommend that people with severely impaired immune systems be vaccinated with a 4th dose.

The Danish Health Authority also continues to recommend that you complete your started vaccination course.

If you experience symptoms of covid-19 and feel sick, you are recommended to stay home until you’re feeling well again.

You are not recommended to be tested unless you are at increased risk of developing a severe course with covid-19. This may be if you are 65 years of age or older, or for other reasons are at increased risk of a serious course of covid-19 - this also applies if you are pregnant. If you are at increased risk, you may be in the target group for early covid-19 treatment.

If you are at increased risk and feel ill, you are advised to have a PCR test or self test taken. If you test positive, it is recommended that you contact your own doctor as soon as possible, as it is your doctor who will assess whether you can receive treatment for covid-19.

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 coughs or sneezes, most droplets fall to the ground. Most of these droplets, so-called microdroplets, can remain 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.

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.

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 hand sanitiser is equally effective. You should always wash your hands if they are visibly dirty or wet, after toilet visits or changing nappies, and before you handle food. Hand sanitisers only work properly when your hands are dry and not visibly dirty.

Remember to cough in your sleeve or a handkerchief. This prevents droplets from spreading. Wash your hands or use a hand sanitiser afterwards. Pay attention to hand hygiene when shaking hands.

Please remember to help children maintain good hand hygiene.

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

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

Places where a face mask may be required


When travelling

There are no longer requirements for face mask at Danish airports, but be aware that some European airports still require face mask.

You need to check if your airline requires you to wear a face mask or visor on board the aircraft.
