Every day, Doctor Jimmy Mohamed answers your questions and reacts to the news on health.

This Monday, he warns about the increasingly widespread use of visors, which can in no way replace a mask.

They are only complementary, and again, in well-defined circumstances. 

Visors flourish on television sets or in restaurants.

But can these transparent objects, whether they cover part of the face or its entire face, replace wearing a mask?

As we know more and more about how the coronavirus is contaminated, wearing the visor alone can be quite unnecessary, even dangerous.

In fact, the visor does not protect postilions and does not protect others either.

The decryption of doctor Jimmy Mohamed. 

"The visors are neither an alternative nor a means of replacing the wearing of the mask. To understand, let's come back to the mode of contamination. Obviously, you can get sick if I spit on you. This mode of contamination through the postilions is rather classic The flu, or any respiratory infection, is spread this way.

Coronavirus: follow the evolution of the situation Monday, October 5 

But that's not all.

The coronavirus is also transmitted by aerosol.

Speaking or even breathing will deposit micro-droplets even lighter than air.

They will therefore remain suspended in a room.

This is why a visor will absolutely not protect you.

On the contrary, it will put you in danger.

You also expose others to possible contamination.

This is why we must no longer put visors, including on TV sets, among the public.

On the other hand, we can offer spectators an inclusive mask if we really want to see their face.

Visors were worn at the start of the epidemic in some restaurants because at that time we did not have masks.

So we could tell ourselves that it was better than nothing.

Now this is no longer acceptable.

In the hospital, the visor is sometimes used in addition to the mask, since contamination can also take place through the eye.

If the doctor is close to the patient, he may indeed be splashed in the eyes.

Complementary barrier gestures

Other barrier measures can also be implemented.

Wearing a mask, washing hands and respecting physical distancing are essential.

But a fourth point is important: you have to ventilate the rooms you are in as much as possible.

This is what makes it possible to renew the air and perhaps to prevent, when there are people in a room, that everyone gets sick.

This may be something to get used to, even this winter.

In addition, it is not very popular but I think we will have to relaunch the StopCovid tracking application a little, since it was launched after containment, when we perhaps did not have it. not necessarily need.

But now, the epidemic is less manageable in Paris, Île-de-France and other regions.

It is important to trace the virus.

So try to download this app.

It doesn't matter if the Prime Minister didn't download it, it would be clear if the policies were exemplary.

I recommend it to you.

Last remark: if we are there, it is also thanks to the French.

If the French did not wear masks and wash their hands, the situation would be unmanageable.

So we must not make them feel guilty, on the contrary.

Thank you."
