Since the arrival of the Omicron variant in Mexico, the number of infections has increased considerably, so it is essential to adhere to the health protocols of the authorities, such as the use of face masks or vaccination, etc.
In view of the foregoing, the Special Commission for Emergency Care due to COVID-19 of the National Autonomous University of Mexico (UNAM) published a series of recommendations to maintain health safety in activities face-to-face
Among them, he highlighted the recommendations on the types of masks that should be used more frequently to reduce the chances of infection by the SARS-CoV-2 virus.
According to the UNAM, the main objective is to avoid forms of contagion through aerosols produced by a person infected with the virus (with or without symptoms) and that is made by breathing, talking, coughing, sneezing, blowing, shouting, singing and breathing.
In this, a mask is a great help, as it decreases (filters) the amount of virus that an infected person exhales and limits the amount of virus that a person nearby inhales.
It is necessary to use this accessory when in contact with the sick, when visiting public places outside the home and when living with other people in closed places or even in open spaces if the distance is close. In addition, they pointed out that it is not convenient to talk closely with other people
For the so-called masks to fulfill their objective, it is necessary that they have a series of characteristics studied and established by the members of the Commission:
° Fabric face mask: have three layers, and be made of a natural fiber, such as cotton.
° Disposable surgical mask: it must also be three-layer. The effectiveness of both can be measured by their ability to prevent the passage of light through them.
° Face masks N95, KN95, KF94, FFP3, FFP2, FFP1: these are the most efficient masks; however, they recommended that it only be used in scenarios where the risk from patients is greater. For example, in a doctor's office, in a hospital or for the care of a contagion at home.< /b>
The foregoing, given that it was identified as a limited availability face mask, in addition to being uncomfortable for common use, so they are not convenient to use on a daily basis, since they could generate risks additional due to its inappropriate or interrupted use.
° Combine face masks: for all people who use double masks to increase their effectiveness, the UNAM recommended that they be two different types of materials and place the most efficient one first and the minor.
In addition to having a suitable face mask, they also stressed that it is necessary to use it correctly, according to the National Autonomous University of Mexico, so its effectiveness will be indicated.
With your mask you must cover the nose and mouth at the same time and be adjusted to the bridge of the nose and the skin of the face without folds, to avoid the free entry of air through the corners .
Once in place avoid touching it from the front, it should be removed by the adjustable straps and wash your hands after doing so. Cloth face coverings are washed immediately after use.
