Austria has introduced major restrictions on movement, urging Austrians to self-isolate, banning gatherings of more than five persons and further reducing entries from other countries in a bid to contain coronavirus.
It was not clear whether the restrictions were meant to come into force immediately, although restaurants were ordered closed from Tuesday.
"Austrians are being summoned to isolate themselves," Chancellor Sebastian Kurz's office said in a statement on Sunday.
"That means only making social contact with the people with whom they live."
Visitors from Great Britain, the Netherlands, Russia and Ukraine would not be allowed into the country, the chancellor's office said in a statement, unless they undertook two weeks of home quarantine or had a current health certificate.
