Nearly 46 million French people are preparing to have to respect the curfew from 9 p.m. to 6 a.m. this weekend.
This shows the level of concern of the health authorities about the spread of the virus in France.
"The month of November will be trying," Prime Minister Jean Castex warned on Thursday when the new restrictive measures were presented.
The government expects in particular an increase in admissions to intensive care units in the coming days, and even in the coming weeks, and an increase in deaths.

In such a context of health degradation, fears are great about the consequences of this second wave for our seniors.
If it is false to state that young people are spared from the serious forms of the virus, Public Health France recalls in its latest epidemiological bulletin that 65% of patients admitted to intensive care units are aged 65 and over.
In this age group, the virus is spreading more and more quickly.
Since the beginning of September, the number of cases has increased six-fold while the number of hospitalizations and intensive care admissions has increased five-fold over the same period.
Targeted data on the over 65s
On Wednesday, Public Health France made very precise epidemiological data available to the public, refined by municipalities and even by neighborhoods.
What to discover a new map of the health situation in the country, making it possible to better locate the territories in which the virus circulates the most, by observing the incidence rates, that is to say the number of new cases recorded over seven days for 100,000 inhabitants.
It is possible to further refine these results to measure the circulation of the virus only among the elderly.
When contacted to find out about the methodology used, Santé Publique France confirms that the incidence rates for people over 65 are reported at 100,000 inhabitants over 65.
This is what makes it possible to compare the different territories with each other.
The map obtained, despite lower rates on average, perfectly matches that of the incidence of all age groups combined.
There are the areas most severely affected globally: around Lyon, Paris, Lille and Marseille.
Areas less affected by the virus are also affected by older populations.
This confirms in a striking way a finding already established by scientists: when the virus begins to circulate in a given territory, often first among the youngest, it inevitably ends up hitting the elderly.
Certain correlations, which one might think obvious, are however contradicted by certain illustrations.
The municipalities or districts (for Paris, Lyon and Marseille) in which the rates of the population aged over 65 are the highest are not necessarily the most affected.
In the Hauts-de-Seine, for example, the towns of Neuilly and Sceaux have a similar rate of population over 65, of 22% and 21% respectively.
However, the virus circulates much more strongly in the first than in the second municipality.

Elsewhere, in the region, all the major trends are confirmed.
The virus is already circulating very widely among this segment of the population in the Lyon region and in a very large radius.
A trend that is just as true for the surrounding cities: Saint-Etienne, Clermont-Ferrand, Le Puy-en-Velay, Grenoble, Chambéry or even Annecy.
The trend is the same on the Marseille coast and in the North region, which today are among the main sources of contamination in the territory.
Similarly, the slower circulation of the virus in Brittany is also confirmed for the elderly, despite the presence of some epidemic foci.
In the majority of municipalities in the region, the incidence rate of people over 65 remains below 10 newly infected people in seven days per 100,000 inhabitants.
By crossing epidemiological and demographic data, it is possible to identify cities with a large elderly population and high incidence rates.
This is the case, for example, of two towns in the Var, Sanary-sur-Mer and Bandol, which both have nearly 39% of the population aged over 65, for incidence rates greater than 250. And one vigilance which must, in both cases, be total.
