A seven-day quarantine will be imposed on arrivals to Greece from the United Kingdom, starting 6 a.m. Monday, the General Secretariat for Civil Protection announced Sunday.
Arrivals from any other country continue to face a 3-day quarantine. The measure affecting the UK has to do with the discovery there of a new coronavirus strain.
Several European countries have halted flights from the UK altogether.
Existing measures affecting all international arrivals include a negative Polymerase Chain Reaction (PCR) test administered less than 72 hours from arrival and a rapid test upon arrival.
