Masks to protect us from the Coronavirus
Considering the worldwide spread of coronavirus as a pandemic, the problem has arisen about the types of masks we can use to defend ourselves against COVID-19.
Because there's a lot of misleading knowledge on the internet, we're telling you today what the World Health Organization is saying about its use.
The coronavirus strain COVID-19 continues to spread around the world, in what has already been identified as a pandemic by the World Health Organization (WHO). This has affected the kinds of face masks that are being sold and that people have started using massively.
We know that COVID-19 is transmitted by air through droplets that are expelled through the infected nose and mouth. It is a transmission of aerosols, as it is called, andit is fair that it might be beneficial to use a mask.Various forms of masks do not have the same effect for both coronavirus and other related transmission pathologies, such as flu. The microscopic scale of the virus and the particles that hold it play an significant role here.
They are the masks of famous people. They owe their name to profession in operating rooms. Of this purpose, they are not intended to avoid the spread of viruses but to protect against splashes of fluid. Surgeons and medical personnel put them on so that, for example, the patient's blood doesn't touch their mucosa.
The barrier they build is physical, but they are ineffective in preventing infection, the WHO has always remarked. Similar to COVID-19, its use on the streets is more
a placebo for those using it than a preventive measure.
Those systems are more complicated than the operating mask. They include a filter on their forehead that prevents other microparticles from moving from outside to inside. There are three filter levels: First level: formally called FFP1 or P1, to defend against infectious aerosols they are the least effective of this category. These are in fact used to deal with toxic materials, such as brick dust in building.
Second level: FFP2 or P2 masks are a type of system that filters up to 92 per cent of circulating particles, allowing up to 8 per cent of circulating particles to move within. The WHO recommends masks which filter 95 percent or more against coronavirus, that is, this type is at the limit of recovery
Who should wear face masks in the coronavirus pandemic?
Besides knowing which masks are successful and not comparable to COVID-19, it is necessary to identify which conditions warrant their use and which do not. The departure of all people, with surgical-type
masks all the time, is obviously inefficient.Most countries have stated, through their health ministries, that in thesetimes there are two more specific reasons for the use of masks:those traveling from an region with high virus transmission, and more so if they have signs consistent with coronavirus – fever, dry cough, decline. We will wear the mask for a total of 14 days, which is the estimated time of incubation.
Both clinicians who handle suspicious cases in health clinics, as well as patientswith symptoms that are admitted without isolation, or in waiting rooms for consultation. As explained previously, these people should use an effective form of mask, and not the pure mask. Devices should be given which have at least FPP2 filters. And other steps that are still symbolic, such as regular hand washing, isolation andquaran tine when necessary, as well as the general hygiene of theutensils, must be applied to the mask use. The masks alone aren't the whole solution
Recommendations for the use of masks in the coronavirus
The type of mask to select depends, as we describe well, on the filter, and the WHO recommends that they be FFP2 or higher.It's not like we all ought to wear it either.These can be used for tourists, as well as health professionals, who come from places of heavy transmission and suspicious events.
The mask has to cover the nose and mouth properly and you must take it from behind to remove it. When we detach everything from the front by taking it away, everything we've done to take care of ourselves will lose meaning. Likewise it should not be disturbed when it is in operation.
