Chinstrap is a term that comes from beard: the area of the face below the mouth. On Argentina, Uruguay, Paraguay Y Bolivia, the concept is used to refer to a face mask (A mask that covers the nose and mouth to protect against pathogens or harmful agents).
What a chinstrap or mask does is minimize the chances of the person inhaling or exhaling infectious or harmful particles. In this way, it protects whoever uses it and also helps to take care of the Health of others.
Chinstraps are used by doctors, nurses and other workers of the Health. With the coronavirus pandemic, its use spread to the general population since, according to many experts, they contribute to reducing the spread of virus.
The chinstrap is most effective in blocking possible viruses and bacteria that the user himself could expel through the mouth and / or nose. In other words: if an infected subject wears a chinstrap, the chances of infecting someone are reduced because this mask works as physical barrier.
That same barrier can also prevent viruses and bacteria from entering the person’s body, although in this case the effectiveness is less. Another advantage of the chinstrap is that it prevents the user from touching the mouth and the nose, thus making the transfer of the pathogen impossible.
It is important to note that, as the notion of chinstrap is associated with the beard, there are those who encourage the use of the expression mask or mask to specify that the mouth should be covered, as well as the nose.
