Belgium, Denmark, Lithuania and San Marino have been moved to Estonia's European arrivals 'Red' list, meaning a 10-day quarantine period if unvaccinated, starting Monday. Austria, Norway, Slovenia and Sweden have been moved to the 'Yellow' list, and these states' arrivals must present proof of vaccination on arrival in Estonia, or proof of a recent negative coronavirus test, or of recovery from the virus. No European states have been moved up to the 'Green' list, which now consists of eleven states.
