The central Swiss canton of Solothurn has become the ninth to put in place a compulsory mask requirement in shops.
Authorities decided on August 28th that masks will be compulsory in shops from Thursday, September 3rd onwards.
On Friday morning, the canton reported 21 new cases of the virus within the previous 24 hours.
As reported by the Solothurner Zeitung, authorities had been reluctant to put in place a mask requirement due to the canton’s location.
Solothurn borders several other cantons, with authorities concerned the mask rule would encourage residents to go shopping across the border.
In addition to Solothurn, eight other cantons have put in place compulsory mask requirements in shops: Zurich (from August 27th), Fribourg (August 28th), Valais (August 31st) and in Basel City, Geneva, Neuchâtel, Vaud and Jura.
Masks have been required on public transport in all Swiss cantons since July 6th.
