According to art. 9 of regulation nr. 18/2021 regarding quarantine, isolation and testing for COVID-19 at the Icelandic border the Chief Epidemiologist retains the authority to issue exemptions from screening and quarantine for health care workers, police and workers involved in transport of goods or services who follow the instructions of the chief epidemiologist while travelling abroad for work. Due to changed circumstances with the initiation of COVID-19 vaccination in Iceland, all exemptions issued in 2020 are no longer valid.
