Super-contaminators, wearing a mask at home and psychiatric disorders: Dr Jimmy Mohamed tells us about three little-known facets of the Covid.

What is a "super-contaminator"?

In theory, a patient with coronavirus can contaminate, in the absence of barrier gestures, two to three people.

Which, in turn, risk contaminating two to three more.

In reality, some patients will infect one or two people, or even none.

And the chain of transmission of the virus will die out.

But, for some reason scientists do not yet understand, some patients will infect 10, 20 or even 30 people.

They are "super-contaminators".

At the moment, it is impossible to identify them.

Some of them are even asymptomatic.

However, they are carriers of a huge amount of viruses.

"This is why we must be masked at all times, even when there are no symptoms," advises Dr Jimmy Mohamed.

These "super-contaminators" need "super events" to spread the virus.

These are typically bars and restaurants, gyms or family events, wedding or birthday party types.

This is why these places are closed and these gatherings are prohibited.

Dr Mohamed also calls for the greatest vigilance when deconfinement begins.

Wear a mask at night when you are sick

If you are sick with the coronavirus and are in quarantine at home with other people, Dr Mohamed recommends wearing a mask, even indoors.

In fact, by wearing a mask, you decrease the viral load, that is to say the quantity of virus, that you transmit.

You may thus avoid infecting your loved ones.

And if they still get sick, "they would do a less severe form", assures Dr. Jimmy Mohamed.

In the event of psychiatric disorders, consult quickly 

A US study of 60,000 coronavirus patients showed that within 3 months, 20% of them develop psychiatric disorders, such as mood disorders, anxiety disorders or insomnia.

That is why, if you have caught the Covid and you experience symptoms of depression, anxiety or sleep disturbances, do not hesitate to consult professionals to help you.
