The Swedish Government has decided that foreign nationals will have to present a negative test result for ongoing COVID-19 infection upon entry into Sweden, regardless of where they are arriving from. The aim is to reduce the risk of spreading the new variants of the COVID-19 virus that have been detected in a number of countries. As a general rule, the test must not be more than 48 hours old. Foreign nationals aged 18 and older are subject to the test requirement, with the exception of certain categories of travellers so as to ensure that there are no unintended consequences.
The regulations entered into force on 6 February 2021 and will apply up to and including 31 October 2021. Please click on the link to read more: Negative COVID-19 test required for entry into Sweden - Government.se
