Mask and Coronavirus :

Mask and Coronavirus information is available here in this topic.The mask has become in public debate the central element of deconfinement. Several studies attest to its effectiveness against the transmission of SARS-Cov-2.

However, other scientists denounce biased conclusions and warn against the false security conferred by wearing a mask.

”  If you are in good health, you should only use a mask if you are caring for a person suspected of being infected with Covid-19, ” clearly states on its website the World Health Organization ( WHO ).

In other words, the mask is not recommended for the general public . ”  There is no evidence that wearing a mask by healthy people can prevent being infected with respiratory viruses , ” insists WHO.

A position that the government has long defended, before making a 180 ° turn around in front of the arguments of other scientists, to impose the wearing of masks in compulsory transport.

 On April 22, the Academy of Medicine called on all French people to immediately wear a protective mask for the general public, even handcrafted , as soon as they leave their homes. ”  Taking care not to contaminate others is not optional, it is a civic attitude which must be made compulsory in public space “, clarified the Academy. “

The use of a general public mask by asymptomatic carriers, when it is well used and well worn, greatly reduces the transmission of the virus“, Also confirms the High Council for Public Health (HCSP)

The contradictory studies are linked:

In the defense of the government, it must be said that the contradictory studies are linked. On April 12, a South Korean study concluded that masks , including surgical masks , were ineffective in limiting transmission, due in particular to the size of the viral particles capable of passing through the masks.

new study  of Delve Group ( Data Evaluation and Learning for Viral Epidemics ) of the  Royal Society , based on previous research, said for his part that ”  the widespread adoption of face masks can help control the epidemic of Covid-19 by reducing the emissiondroplets in the environment by asymptomatic individuals. 

It also confirms the experiences of countries that have adopted this strategy, ”say the authors – even though most of the masks worn in Asia are aimed most of the time at protecting themselves from pollution .

No solid proof of the effectiveness of the masks:

“There is no solid proof that the mask can reduce the transmission of the virus in the community”, rejects Ben Killingley, consultant in acute medicine and infectious diseases at the University College hospital  of London, questioned by the  Guardian . ”  The studies on facial masks were not carried out during a pandemic or in the context of a new virus, ” warns the specialist.

In addition, the tests are carried out in the laboratory, far from the real conditions of everyday life.

However, according to several specialists, the disadvantages of masks far outweigh its benefits. ”  The use of medical masks on a large scale can create a false sense of security, and lead to the neglect of other essential measures, such as hand hygiene and physical distancing ,” notes for example the WHO.

Secondly, the discomfort caused by the mask leads people to touch their face more frequently with their potentially contaminated hands, which increases the risk of catching the virus.

Not to mention the difficulty in breathing through certain masks. In fact, we see a large number of people who have demanded masks with horns  and screams to wear the masks … on the chin. ”  I am allergic to fabric, ” pleads Sophie, a cashier in Strasbourg, for example.

Last concern :

The mask must in principle be washed after each use, which is far from being the case.

The precautionary principle before scientific evidence?

”  Before implementing public interventions involving billions of people, we need randomized controlled trials at the population level or at least follow-up observational studies with comparison groups ,” concludes Antonio Lazzarino, of the Department of University of London Epidemiology and Public Health . Precautions that the government did not expect to order 3 billion masks and to expand its distribution to supermarkets.
