French Prime Minister Jean Castex has responded to a steep increase in infections with a series of measures including increased testing and compulsory face-coverings in Paris.
The number of “red zones” where the virus is in active circulation has risen from two to 21.
If France did not act fast, the spread could become “exponential”, he warned.
A number of European countries are seeing a new surge in cases, and Germany is also planning tighter rules.
France has recorded its highest number of new daily infections since the end of the lockdown in early May, with an additional 6,111 registered over the past 24 hours.
A further 48 deaths were announced on Thursday, but mortality figures for Wednesday had not been available because of an IT problem. Overall, more than 30,500 people have died and nearly 300,000 have been infected in France.
Mr Castex said Covid-19 was “gaining ground” across the country. There was an “undeniable resurgence of the epidemic”, he said.
Masks for Paris
Promising to do everything to avoid another widespread lockdown, the prime minister said wearing a mask would become mandatory in the capital.
While individual streets and areas in the capital already have rules on wearing face-coverings, this new rule will be far more extensive, covering not only Paris but its inner ring of Seine-Saint-Denis, Hauts-de-Seine and Val-de-Marne.
From 08:00 on Friday (06:00 GMT), all pedestrians will have to wear face-coverings in public areas, as well as people on bicycles, motorcycles, scooters and a variety of other mobility vehicles.
Paris is already a red zone, along with the southern area of Bouches-du-Rhône, where France’s second city Marseille made masks compulsory from Wednesday evening.
The whole inner ring is now a red zone too, along with a broad expanse of the southern coastal fringe and the Gironde area around Bordeaux.

Masks will also become part of normal life for French schoolchildren aged 11 and over. The World Health Organization has recommended use of masks in school from the age of 12. Masks are already required in most enclosed public spaces and will be mandatory in workplaces from next month.
Meanwhile, Health Minister Olivier Véran has promised to step up Covid testing to reach a million tests a week in September, with the aim of making them available to “anyone who needs one and anyone who wants one”.
What has Germany decided?
Masks are also a key part of Germany’s tougher restrictions aimed at curbing a renewed rise in cases. Although Germany has not seen the scale of Covid-related deaths as many other Western European countries, the federal government and 16 states have reached a draft deal on new measures:
- A minimum €50 (£45) fine will be slapped on anyone breaking rules on face-coverings – in shops, public transport or elsewhere; but one state in the north-west is still holding out against a fine
- Big events will be banned until the end of the year, although regions will be exempt if they have a low infection rate and participants are limited to those areas
- That means there is little chance of spectators returning to Bundesliga football matches
- There will be an end to free tests for holidaymakers returning from high-risk countries after 15 September. Such travellers already have to self-isolate for 14 days.
Health minister Jens Spahn argues that German labs are reaching capacity and testing should be more targeted. But Volkmar Weckesser, whose Centogene company conducts tests at Frankfurt airport, told the BBC that “we are not even close to reaching capacity”.

Meanwhile, a group called “Querdenken” (Think outside the box) is challenging a Berlin ban on a march on Saturday against Covid-19 restrictions. The protest has already seen 22,000 people sign up. A march on 1 August attracted around 20,000 people, made up of mainly Covid-deniers and far-right activists.
