The Scientific Council is alerting to an increase in cases of coronavirus in recent days. Experts insist on the need to wear a mask, especially in confined spaces, on pain of witnessing a resumption of the epidemic in the coming weeks.

DECRYPTION

For now, the coronavirus epidemic seems under control in France, with a continuous decline in the number of people hospitalized in intensive care. But the Scientific Council warned Thursday of the growing non-respect of social distancing, especially in closed spaces. These days, there are as many as 500 cases diagnosed per day, which is enough to start an epidemic again.

Barrier gestures "not respected"

"I would like to reiterate the fact that we are very struck by the fact that barrier gestures and social distancing are no longer respected," explains Professor Jean-François Delfraissy, president of the Scientific Council, at the microphone of Europe 1. "We must not believe that we will remain on this quiet balance if we continue to no longer use barrier gestures and social distancing."

According to scientists, there is a risk of resumption of the coronavirus epidemic this summer if we stop wearing masks. And it is in confined spaces that the risk of contamination is greatest today. "It's basic physics," said Professor Bruno Lina. "These micro-droplets have the capacity to remain in suspension for a long time in the atmosphere. If there is no draft, with the presence of infected people, they will gradually enrich the confined space and increase the risk of contamination of people who will frequent these spaces. "

Wearing the required mask

At this rate, the epidemic can resume during the holidays, expected by many French people. "Can we spend the summer like this? It's probably dangerous," warns Franck Chauvin, professor of public health, about the laxity in the application of barrier gestures.

"It would certainly be preferable for the whole population to get into the habit of wearing a mask in closed environments," continues the specialist. The members of the Scientific Council hammered it out: wearing a mask is for the moment the only known measure that is really effective in guarding against contaminated droplets. And thus avoid a dreaded second wave.
