Austria is imposing a blanket ban on all people entering from Italy unless they have a medical certificate, Chancellor Sebastian Kurz has proclaimed, though Austrians currently in Italy are strongly encouraged to return.

“There will be an entry ban for people [travelling] from Italy to Austria, with people who have a medical certificate being an exception,” Kurz said on Tuesday, as cited by local media.

Meanwhile, Austrians who find themselves in Italy will be allowed to return, but “they must be kept in isolation for two weeks.”

Interior Minister Karl Nehammer said police will scrutinize movement at the Italian border. “A transit through Austria is allowed as long as there is no stopover in Austria,” the official said, noting that cross-border traffic in both directions has already dropped by more than half.
