A voluntary 14-day quarantine period applies to you if you arrive in Finland from a country that is subject to travel restrictions or you have spent time in a country that is subject to travel restrictions during the preceding two weeks. You should avoid using public transport during the self-isolation period.
You can reduce the duration of your self-isolation with two voluntary COVID-19 tests. When arriving from abroad, the first test at the airport will be free of charge. You can take the second test at the soonest 72 hours after arriving in the country. Read more detailed instructions at THL’s website.
