The American Department of Public Health recommends again and again the wearing of the mask to the face, but advises the population not to wear it with valves or sales, features that would let the new coronavirus spread anyway.

Wearing any coverage is therefore not necessarily useful for protecting yourself from COVVI-19 or protecting others.

"Masks with valves do not work.What happens when we breathe, and we have known this for a long time, is that the valve opens to let the air escape, what could infect you, "said Gavin Macgregor-Skinner, Washington ExpertGlobal Biorisk Advisory Council (GBAC), in an interview broadcast by CNN Friday.

In other words, this means that the famous N-95 masks, these masks used by health workers, on the front line of the battle against the coronavirus, should not be wooded by the population.

Woven

Now, what is a good mask?

"It must really be composed of a tight woven material.Sheets make ideal facial masks because they can be cleaned, give macgregor as an example.Any mask that looks like it works well.Any material that stretches does not make a good mask because it allows the droplets to spread.»»»»

In the United States, it is estimated that, if 95% of the population wore the mask, we could avoid around 70,000 dead.

"Out of doubt, if you prevent the virus from grasping its chance from transmitting, it slows down the pandemic," said Professor William Hanage, epidemiologist of Harvard University.If you remove him enough likely to be transmitted, he will extend.Everything you can do to take the chance to infect other human beings help a lot.The masks form a large part of this effort.»»»»

D^r Desmond Carson, urgentiste, en rajoute. «C’est un très, très petit effort, un effort minime pour minimiser les pertes humaines»»»», dit-il, qualifiant de «ridicule»»»», d’«irrespectueux»»»» et d’«inhumain»»»» le refus de porter un masque.

In Quebec, as back to school approaches, we can expect high school students to wear a mask at school, if we trust the new recommendation of Health Canada which even suggests the portFrom 11 years old.

Furthermore, the Ministry of Health does not intend to wear the mask in the common places of residential buildings, even if a second wave of the COVID-19 is very likely in the fall.
