For Pr Jean-François Delfraissy, president of the Scientific Council on the coronavirus, "the objective of confinement is to limit the number of serious forms to allow our care system to remain effective."


France has been confined since Tuesday March 17 at noon. This Friday, Prime Minister Edouard Philippe recalled that the days to come were going to be difficult. The government should soon announce the likely extension of the containment. The Scientific Council recommended Tuesday to lengthen it, suggesting a total of six weeks, until the end of April.

Thursday in Le Figaro , Professor Jean-François Delfraissy, president of the Scientific Council on the coronavirus appointed by the government, indicated that " the objective of containment is to limit the number of serious forms to allow our care system to remain effective . But, he warned, " the epidemic will continue to turn after confinement. It will not be finished until we have achieved group immunity. That is to say when a large percentage of the population will be immune. "

William Dab, Director General of Health during the SARS crisis, told us that " if each of us respects strict confinement, that we are serious, disciplined and rigorous, that we accept these few weeks of deprivation of relative freedom, the rate of contamination can drop low enough to break the dynamics of the epidemic. "

In epidemiological terms, it is necessary to succeed in limiting the “ reproduction rate ” of the virus, noted R0 (R zero). This parameter quantifies the average number of people who are infected by an infected person during the entire period in which they are contagious. Specialists estimated 15 days ago that it was close to 3 in France for the coronavirus. "To stop the epidemic, we must reduce this rate below 1" , deciphered Samuel Alizon, CNRS researcher at the laboratory " Infectious diseases and vectors: ecology, genetics, evolution and control " of Montpellier. This amounts to dividing our social interactions by four.

Since the implementation of strict containment measures, about 3.7 million checks have been carried out throughout France, said Thursday evening the Minister of the Interior Christophe Castaner. More than 225,000 minutes have been drawn up by the police.

The latest health assessment in France (Thursday March 26) brought to 1696 the number of Covid-19 deaths registered in hospital since the start of the epidemic at the end of January, and 3375 patients were in intensive care (+548 in one day) , out of a total of 13,904 (+2,365) hospitalized patients.
