Masks are already compulsory on public transport, but will become mandatory in all indoor places frequented by the public, Prime Minister Jean Castex said in the Senate.
President Emmanuel Macron had announced the change in his July 14th TV interview, and had given August 1st as a deadline for it to happen.
Now it looks as though the change will be introduced earlier, but Castex did not give a precise date.
Here's what we know so far about the planned new rules.
Castex said that an August 1st start date appeared “late” to many, and announced “the decree will enter into force next week.”
Regarding mask-wearing in office buildings, the premier said employers will need to consider “an evolution of health protocols governing the activities concerned.”
In the latest official data, released on Wednesday, France had seen 133 new coronavirus patients hospitalised in 24 hours, and 17 new admissions to intensive care.
This was down from a high of 4,281 people hospitalised in one day in April.
