Mask and Coronavirus what if mask did more harm than good?
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( ).
In other words, the mask. ” There is no evidence that wearing a mask by healthy people can prevent being infected with respiratory , ” 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,called on all French people to immediately wear a protective mask for the general public, , 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, including surgical , were in limiting transmission, due in particular to the size of the viral particles capable of passing through the masks.
Aof 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 of by reducing the droplets 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.
No solid proof of the effectiveness of the masks:
“There is noproof that the mask can reduce the in the community”, rejects Ben Killingley, consultant in acute medicine and infectious diseases at the University College hospital of London, questioned by the . ” The studies on facial masks were not carried out during a 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 totheir 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 withand screams to wear the masks … on the chin. ” I am allergic to fabric, ” pleads Sophie, a cashier in Strasbourg, for example.
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.
