Helsinki Airport has a COVID-19 testing point organised by the City of Vantaa that is meant for all passengers arriving in Finland. The test is free of charge, and the testing point is located in the gate area. Passengers are guided to the testing point after landing.
Upon arrival, you may discuss with the staff of the testing point if they recommend that you take a COVID-19 test at the airport if, for instance, your previous test was conducted less than 72 hours before or the duration of your journey is less than 72 hours.
At other Finavia airports, contact information for the local health authorities is provided in brochures distributed at the airport terminals.
