Anyone returning from red areas within the Schengen/EEA region or countries outside the Schengen/EEA region must stay in quarantine for 10 days after the date of their arrival in Norway. This is referred to as travel quarantine.
See NIPH for an overview of the relevant countries.
Traveling through a yellow area en route to Norway
If you travel from a red area and pass through one or several yellow areas, the time you spend in these yellow areas is counted as quarantine time. As an example: If you travel from a red area and pass through a yellow area and spend five days in this yellow area before entering Norway, you are left with only five more days of quarantine duty.
You are not exempt from quarantine duty after traveling through a yellow area on your way back to Norway if less than 10 days have passed since you were in a red area. The travel quarantine period is set to 10 days, irrespective of whether you complete all or parts of it in Norway.
If you are in travel quarantine the following applies
You should stay at home or in another suitable place of residence
For a residence to be suitable for implementation of your quarantine duty, it must be possible to avoid contact with anyone other than those you normally live with.
This means that accommodations where you have to interact with other guests are not suitable for quarantine. Staying in a motorhome, caravan, tent or cabin at a camping site is not an acceptable address for implementation of quarantine duty if you share a toilet, kitchen or other rooms/facilities with people other than your close contacts/travel companions. The same applies to addresses where you share rooms/facilities with others than those you usually live with, such as a dormitory or other place of residence with a shared bathroom or kitchen.
You can only go outside of your home or place of residence if you can avoid close contact
If you go outside, you must avoid close contact with anyone other than those you normally live with.
You can only visit public places if you can avoid close contact with those you do not live with. If unavoidable, you can conduct necessary errands in the store or pharmacy, but you must maintain a minimum of one metre distance to others and avoid queuing.
Travelling by public transport is not allowed. Those arriving in Norway can nevertheless travel by public transport from their place of arrival to the place where they will be in quarantine, and those leaving Norway prior to completing their quarantine duty period can travel by public transport to their place of departure. Persons in both these groups who are exempt should wear a face mask when traveling by public transport if they are above the age of 12 years old.
You should not go to work while in travel quarantine, but you can work from home. Pupils, students and children cannot go to school or kindergarten.
If you develop symptoms of COVID-19 while in quarantine
If you develop symptoms of COVID-19 while in quarantine, you shall contact the local health services for testing. If you are tested for COVID-19 and the result is negative, you must still stay at home for the rest of your quarantine period. You must also stay at home if you have any symptoms and not go out until you have recovered and are free of symptoms.
Symptoms of COVID-19 can be coughing, fever, breathing difficulties, reduced sense of smell and taste, headache, lethargy and muscle pain.
