International travellers to Turkey will now need a negative Covid-19 test certificate to enter the country Health Minister Fahrettin Koca said. He added that a PCR test taken at least within a 72 hour window would be mandatory and the new rule will be applicable to all sea and land arrivals. In case a passenger does not have test results, they will quarantined at their destination. While those arriving from UK, Denmark and South Africa in the past 10 days will not only have to show a negative result but also go into mandatory quarantine for at least 7 days.
