General guidance

The most effective way you can help prevent the spread of infection is by following our 5 steps and incorporating them into everything you do.

Also remember to help children follow the guidance.


1. Stay home if you are ill

If you experience symptoms of covid-19 and feel ill, it is recommended that you stay home until you are well again.

The Danish Health Authority does not recommend that you get tested, unless there is a health professional reason to do so. We recommend that you get tested if you are ill with significant symptoms of covid-19, such as fever, persistent cough, breathing problems, etc., and you are at increased risk of a serious course of illness due to covid-19. You may be at increased risk if you are 65 years of age or older or for other reasons are at increased risk of becoming seriously ill because of covid-19, including if you are pregnant.

2. Open windows and doors and ventilate your home regularly

Airing out effectively prevents droplet spread indoors.

When someone e.g. coughs or sneezes most droplets fall to the ground within a few meters, 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 minutes at least 2 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.

3. Wash hands frequently or use hand sanitiser

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

Washing your hands or using hand sanitizer is equally effective. However, hand sanitizers 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.

4. Clean thoroughly and regularly, especially surfaces that are touched by many people

The risk of contact spread increases dramatically when you touch contact points 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 points frequently and thoroughly using ordinary cleaning products and disinfectants.

5. Cough and sneeze into you sleeve

Coughing and sneezing into your sleeve, elbow or armpit prevents virus-particles to spread in the air. It also prevents virus to spread via your hands. If you cough or sneeze into your hands it is recommended that you wash or use sanitizer on your hands straight away.
