The consequences of the use of masks – what you need to know?
Source:
Since the beginning of the pandemic COVID-19 the question of the need of using protective masks regularly raised
Medical workers wearing surgical masks and there is strong evidence that it limits the spread of respiratory viral infections in hospitals. However, clear evidence that surgical masks protect ordinary people from intrusion or transmission of this kind there. Most likely, the cause is their improper use. As for the tissue masks, which are a huge number of people, then the picture looks even more grim. In this article, you will learn about the existence of four potential consequences of the use of protective masks, which should beware.
facial Mask – the best defense against infection?
Surgical masks consist of several layers of nonwoven plastic material and can effectively filter very small particles, for example, the coronavirus SARS-CoV-2, calling COVID-19. Masks usually contain outer waterproof layer and an inner absorbent layer. Although the masks made from scarves, t-shirts or other fabrics, can not provide the same level of protection and durability as surgical masks, they may block some large droplets and particles exhaled by the media, thereby protecting others from viral exposure.
It is Important to understand that the ability of masks to filter the drops depends on their design. So, multi-layered tissue mask filter is better, but harder to breathe. Read more about what masks are better than others to protect against mers . And yet the question is not so much whether the cloth mask the same good protection as surgical masks (and it's not), but in whether there are serious unintended consequences of the recommendations of its widespread use.

the Big four
As the authors of the article for The Conversation, you need to know about the four potential consequences, which, if not mitigated, can worsen the situation.
thethe peltzman Effect.
The peltzman Effect. assumes that the introduction of a single security measures, such as car seat belts, can lead to other risky behavior, such as speeding. Cognitive distortion in which too many protections and safety regulations increases the risk of accidents due to a false sense of invulnerability, named in honor of Professor of the University of Chicago — Samuel Peltzman.
In the context of COVID-19 has been proven that the use of masks allows people to feel safer and consequently to minimize other effective protective behaviours – social distancing and regular hand washing. Although clear evidence that this is happening during a pandemic there, some of the surveys conducted before the outbreak of the deadly infection have shown that people do worse to wash their hands when wearing a mask.
theProper use of masks
To face masks effectively protect you from infections, they must be used properly, especially when contact with other people. Most previously performed studies, none of which were carried out during the current pandemic – have not considered explicitly the attitude of people to use masks. However, it is important to note that the more severe was the disease and the more receptive was her people, the greater was the likelihood that they will be able to protect themselves during a pandemic. Given the large number of global infections and deaths around the world, people may exhibit a higher than usual level of commitment to the wearing of masks during a pandemic.
theMask – an additional source of infection
In Addition to prevent penetration of viral particles into the body, the mask can act as alternative transmission paths of the virus SARS-CoV-2. To avoid this, they must be properly put on and take off. It is also important to remember that people are touching my face – so, ill-fitting face mask causes people to touch their eyes, nose and mouth even more. As the authors write, after touching the mask, there is a risk of getting the virus on your hands, and with them on other surfaces, such as doorknobs, railings, or tables.
If you are a medical worker, a regular mask will suit you perfectly.
theEnvironmental impact
Fourth, no less important a cause of concern for researchers, are the results of a study by British scientists, according to which if all the population of the UK will start to use daily disposable masks, it will cause 42 000 tonnes of potentially contaminated and non-recyclable plastic waste per year. Needless to say that the UK is not the most populous country in the world. In addition, most people today notice a huge number of used and not properly disposed of masks in public places, which poses environmental and infectious risk. Therefore, it is preferable to use cloth, not disposable masks.
Recall that the national and international bodieshealth recommend the use of protective masks in those places where it is difficult to maintain social distance, for example in public transport. Well, we encourage readers Hi-News.ru wash hands thoroughly, to observe social distance, not to touch your face, use tissue face masks and properly dispose of them after use. Of
