The Norwegian Government is introducing new quarantine rules to contribute to more people being tested and to improve compliance with the quarantine rules. Travellers arriving in Norway from abroad may, at the earliest, end quarantine on day seven if they test negative for Covid-19 twice after arrival. The first test must be taken within three days of arrival, and the second, at the earliest, seven days after arrival.
