The World Health Organization (WHO) insists on not using masks for healthy people, and the authorities have decided to implement these measures, which they consider essential to prevent proliferation and protect people at risk. People with or without symptoms or infection before symptoms
Dr. Carmen Jodar Casanova, a family and community medical expert and senior medical member, insists on the importance of getting used to wearing masks: “According to a seropositivity study, only 5% of the population has been exposed to VIDOC-19. Although the percentage has increased, we are out of the group”. It’s still a long way off. We will be infected and we must stagger this infectious disease. All the measures we are taking are very few, so we will have to continue using masks, especially for citizens, it is inevitable.
So far, it has worked well, but … To avoid taking risks or putting someone at risk, which mask should you always wear? In communicating the new standards, governments are recommending the use of hygienic or surgical masks. For the avoidance of doubt, we will study all types of masks.
On the street, what kind of mask should I wear when I go to work or make a purchase?
The scientific community recommends that all healthy people who are not exposed to COVID-19 should wear hygienic masks. If you have not been exposed to the virus, have no symptoms, and are in good health, you should wear this model when walking, shopping, or riding public transportation.
Additional measures have been taken and surgical masks have also been added to this category. Your doctor promises to recommend them further: “The function of surgical masks is not to infect you or to infect you. It doesn’t matter when you wear it. I recommend using it in this situation.
For example, surgical masks can be bought in supermarkets or drugstores. They cover the mouth, nose and chin, and are equipped with a safety belt that can be wrapped around the head or attached to the ear. They consist of one or more layers of textile materials and can be reused or used once.
They have been tested for four hours. After this period of time, it is recommended to replace it with a new one or, if it is not reusable, to use a previously disinfected product. If it gets wet or deteriorated before that time, it is recommended to replace it with another one.
If it is reusable, you should read the manufacturer’s instructions to understand how to clean your mask and the maximum number of cleanings allowed.
What should I use if I get sick?
If you are infected, have symptoms or suspect you may be infected with the disease, you should discard hygiene products and wear a mask. This is a model used in a clinical setting. Because they are designed to filter out exhaled air, they limit the spread of infectious agents. Their task is to protect people around the carrier by talking, coughing or sneezing to prevent the virus from spreading.
This mask should have a mechanism to fit snugly over the nose, mouth and chin. Depending on its bacterial filtration efficiency (EFB), there are two types: Type I and Type II.
If I want to care for a patient, how should I protect myself?
Whether you are caring for patients in a hospital or working for a “nurse” who lives with your family, you should wear PPE (personal protective equipment). For people who are in contact with the virus and some vulnerable people, but always under a doctor’s prescription, this type is recommended.
These are devices that provide protection to and from the virus (including the user and the other person). They are only sold in pharmacies and specialized institutions to build barriers between potential risks and users, filter the inhaled air and prevent contaminating particles from entering the body.
They can be FFP1, FFP2 and FFP3, depending on the degree of protection they provide. Filters containing particles may also be of three types: P1, P2 and P3.
Which model should I put my child in?
If your child is between the ages of 3 and 12 and has not been exposed to COVID-19, he or she should wear a facemask as large as yours. Depending on the age, there are three sizes of masks. From 13 years of age, they can be used in the same way as adults.
What category does the fabric fall into? Do they have the same protective function?
Fabric masks belong to the category of hygienic masks and can be used if you do not have a disease or have been exposed to a disease.
As for their effectiveness, it depends on the fabric used. “If they are made of common fabrics, they will not be protected, but some fabrics may provide guarantees, such as non-woven fabrics (TNT), which are the same as surgical masks. If they are made of fabric, because there is no other solution, we recommend using double semi-plastic material or TNT. This filter material is usually used in diapers, pads, slips and baby wipes.
In any case, if you buy a cloth mask, read the manufacturer’s specifications to understand the protection it provides. And use manual face masks carefully: “Because they have not passed the verification or test control, their effectiveness cannot be guaranteed.
