Masks will be obligatory for all those aged 11 and over from 8am on Monday “in certain very crowded zones”, the police said in a statement on Saturday.

“All the indicators show that since mid-July the virus is again circulating more actively in the region,” the police said, adding that some 400 people were testing positive for Covid-19 in the region every day, with the 20-30 age group particularly affected.

Paris follows many other towns and cities across France were local rules have been imposed making masks compulsory in the street. National laws make masks compulsory in all indoor public areas, at risk of a €135 fine.

The new rules apply to the city of Paris and the départements of Seine-Saint-Denis, Val-de-Marne and Hauts-de-Seine – all areas that are on the list of départements with high numbers of new Covid-19 cases.

In Val d'Oise masks became compulsory in all open-air markets from Monday, and the préfecture says it will release further details on other areas later in the week.

Within Paris a list has been produced of dozens of streets where the new measure is compulsory including along the banks of Seine, busy central streets, all outdoor markets and the banks of the Canal Saint-Martin and Bassin de la Villette (full list below).

Paris mayor Anne Hidalgo announced last week that she had requested the police to begin work on making masks compulsory in some open areas of the capital.

Anne Souyris, the deputy Paris mayor in charge of health, said: “The aim is to slow down the resumption of the Covid-19 epidemic.

“A second wave is expected. There is an urgent need to reinforce barrier gestures if we do not want to reach a new lockdown.”

“Wearing a mask is difficult, especially when it's hot. If the zones are chosen intelligently, Parisians will wear it.”

Paris police chief Didier Lallement decided to extend the measure to the capital's suburbs, in consultation with local authorities.
