From Monday next week, wearing a face mask on public transportation and in stores will be mandatory in all 16 states in Germany.
Over the past few weeks, German Chancellor Angela Merkel has advocated that people wear masks.
Last week, the federal state of Saxony in the east of the country pushed ahead, making wearing of masks compulsory to curb the spread of coronavirus.
Since then, more and more state leaders have implemented the wearing of masks in their states. Bremen became the last federal region to support the initiative and its senate is set to approve the decision on Friday.
Germany has reported more than 150,000 coronavirus infections, according to Johns Hopkins University. The death toll has risen to 5,094, the country’s center for disease control, the Robert Koch Institute said on Thursday.
