Residents of Austria and England are required to wear face masks in more places on Friday. In this way, the authorities hope to prevent the spread of the coronavirus.
The new rules mean that Austrians must now also cover their mouths and nose when visiting supermarkets, post offices, bank branches and other public buildings.
Similar measures will come into effect in England.
There too, people have to wear a face mask when they visit supermarkets and other shops. Scotland previously made this mandatory.
The mouth mask obligation previously applied to public transport in England and Austria.
The mask is also on the rise in other places in the world. In the Australian city of Melbourne, wearing such face-covering has been mandatory in public places since Thursday.
