Covid: 7 misconceptions on masks that make you run risks

Covid-19 has started almost two years now started.In many countries, the number of new cases explodes, especially with the rapid propagation of the Omicron variant.In France, the virus affected nearly 9 million people and caused more than 120,000 deaths.

With more than 50,000 new cases per day, it is important to take stock of the use of the mask.According to the WHO, using an adapted facial mask such as the KN95 or the N95 on the nose and the mouth is an effective way to fight against the epidemic.As a reminder, the use of the mask in France is compulsory indoors, even for areas subject to the health pass.Regarding outside, its use is advised and can be made compulsory if the situation imposes it by prefectural decision.

Unfortunately, certain received ideas on wearing the mask (or on the vaccine) continue.Here is an opportunity to play "mythbusters" with the help of health experts.

Myth 1: Masks are not necessary if you are vaccinated or healed

Initially, the WHO and the CDC had updated their directives to say that a person who was vaccinated (entirely) or delivery of the disease no longer needed to wear a mask.However with the appearance of extremely contagious variants such as the delta (or more recently the omicron), these organisms have reversed.

From now on, everyone is recommended to wear the mask in public places, because even an immune or asymptomatic person can spread the virus.

Myth n ° 2: a fabric mask alone is enough

At the time of the shortage of masks, many tutorials for manufacturing fabric masks appeared.Although they represent a physical barrier against postilions, they are not enough to prevent a person from contracting the virus.

In summary, a fabric mask alone, it's better than nothing, but it is not as effective as an N95 mask which is much more easily than at the beginning of the epidemic.

Myth 3: Only sick people must wear a mask

It is not because you have no symptoms that you are not carrying the virus.Dozens of studies show that an asymptomatic or presymptomatic person can propagate the virus.

If you go out in public, wearing the mask is the best way to protect you and protect your loved ones.The virus that can be transmitted by air, it is enough that two people do not wear a mask to greatly increase the risk of transmission.

Note that a slightly affected person can transmit the virus to people who are more likely to present a serious form.

Myth n ° 4: The mask increases the absorption of carbon dioxide

When you wear your mask correctly, you may feel like breathing a little more difficulty.This feeling, certainly not pleasant, gave birth to a myth saying that we therefore absorb more CO2 and less oxygen.

The fibers of the mask are not tight enough to cause CO2 imprisonment in the mask.Porter it in a prolonged way, one usual thing for a surgeon for example, therefore is not a problem.

Myth n ° 5: If I wear a mask, no need for social distancing

The purpose of carrying a mask is to limit the transmission of the virus.Unlike a N95 mask which filters 95 % of particles and which is subject to checks, fabric masks manufactured by some people do not necessarily reach this efficiency.In addition, the effectiveness of masks is only optimal if they are perfectly worn, which is not always the case.

As a precaution, barrier gestures are relevant, stay away from people, wash your hands regularly and avoid touching your face.

Myth 6: Masks weaken the immune system

This received idea stems from that which the immune system is strengthened by exposure to bacteria and other pathogens.

According to the American Lung Association, there is no scientific evidence that wearing a mask weakens the immune system.Likewise, washing your hands regularly has no negative impact on immunity, all the more so in adults whose system is already developed.

Myth n ° 7: it is not necessary to wear a mask outside

It is true that if you spend time in your garden or that you hike on a little frequented path, wearing the mask is not necessarily essential.However, being outside does not mean being far from others.

In concerts, frequented streets or amusement parks, the number of people encountered is too large to maintain sufficient distance and avoid the spread of the virus.Thus, it is recommended, even if it is not compulsory in France, to wear an outdoor mask as soon as you come across the world.
