How to avoid omicron infection: FFP2 mask and "well placed"
The mask returns to the street to try to stop this new wave driven by ano.Vaccines, the best weapon to avoid serious cases and deaths, do not protect from infection.The only thing that does is social distance, good ventilation and a well -placed mask, correctly covering the nose and mouth, insist epidemiologists and public health experts.
"Any mask?" Askems as experts asks.The answer is no"."Everything that is not a FFP2 or a surgical mask is like carrying a cooking cloth," says Andreu Veà, founder of Covidwarriors categorically.So, the engineer indicates, "for that it is better not to carry anything, because it gives a false sense of security".
An example of the efficacy of the mask: Malaga's outbreak
To explain the effectiveness of the Andreu masks exposes to Nius the infection in a hospital in Malaga.Sanitary who were working with infected people for more than eight hours and that being well protected did not happen to them, but "they were food and were infected with dozens", all low.The difference is to carry or not mask, it is clear, it emphasizes.A difference that can be seen well in the vignette elaborated by @Mlanda.

Better FFP2 than surgical
The biochemist and molecular biologist José Manuel Batist.This is explained by the professor of the Complutense University on his Twitter account.
"The vaccine does not protect you from not infecting you and on top of the COVID passport I think it does not end up clarifying people," says Andreu Veà, so "I think you have to self -defense with an FFP2 mask, certified and well put", insists.If the well -adjusted FFP2 is taken, "the probability of infection is 0.4 %," he says."The problem is that nobody takes her well tight because we are of a big nose".But for that, the engineer indicates, there are simple and cheap techniques how to put a simple tape by adjusting the garment to the face.

The reason is explained by the founder of Covidwarriors."The surgical mask is designed to fight dropicles, but with the Covid we fight against aerosols.The geticle is greater than 100 micrometers and the spray is lower ".
"The goticle -continues -is like a clean clean.If the drops were fat, you would have to put the nose on the ground to smell it, but no, they are much smaller droplets so that they float, they are suspended in the air for hours for hours.Aerosol is suspended and rises.The Sars-COV-2 travels over aerosols and may be suspended for 12 hours, unless you open the window and ventiles ".
Goticles and aerosols
The objective is to filter aerosols, not droplets.But, as can be seen in the video that accompanies this information, prepared by the technological university of Delft, one of the most important higher education centers in the Netherlands, "surgical presents holes everywhere," says the engineer.Before the omicron, better surgical mask than nothing, but "the best is a FFP2," he insists.
"It's better for people to watch the video and choose," says Veà."Yes, the FFP2" are more expensive, but here the trick is not to infect because, even if you are 15 meters from someone who smokes if you are enough time and unprotected, or very close to it on the street, you will end up smelling, because this isThe same as with tobacco smoke ".
According to the Catalan engineer, this is a matter of probabilities, the more layers you put, the less likely you will be to infect you.So, he concludes, "between FFP2 and surgical depends on yourself and whatever you want your life".
FFP2 and 21% VAT compared to 4% of surgical
If the FFP2 is more necessary than ever, in the face."It is an issue that is going to be addressed by the European Commission, but as it is so urgent," says Andreu, sees with irony - will do so in the coming months. ".
According to Juan Antonio Sanz, spokesman for the Spanish Medicine, Public Health and Health Management, it seems clear that at first we wanted to promote the use of surgical between the population and leave the FFP2 for health personnel, more exposed, "but the issuesEconomics escape me, "Sanz acknowledges.
