Hello !

Masks do not give a 100% guarantee, but if used correctly, they still reduce the likelihood of infection. In addition, it makes sense to use the following recommendations:

... An effective preventive measure is the application of Viferon gel to the nasal mucosa twice a day and before each going outside to create a constant high concentration of interferon in the blood.

... It is important to regularly use personal hygiene products, disinfecting wipes and hand treatment solutions, and after each visit to the street, wash your face thoroughly and rinse your nose.

... Soap contains special substances - amphiphiles, similar to lipids in viral membrane. Soap molecules “compete” with lipids in the viral envelope and effectively “dissolve” it.

... Ethanol with a strength of 62 to 71% when processing the skin for 1 minute inactivates up to 90% of the virus.

… Hydrogen peroxide H₂O₂ 0.5% and sodium hypochlorite NaOCl 0.1% kill up to 98.8% of the virus within one minute.

… It is important to avoid touching your eyes, mouth and nose with your hands. When sneezing or coughing, cover yourself with your elbow, not your palm.

... You need to stay at home. At the same time, physical isolation does not mean social: go to online communication with friends and family.

... You should keep at a distance of 2 meters from each other and avoid close contact with people when going to the store or pharmacy.

Self-stitched masks will not help anything at all. Medical masks will not help prevent infection. The patient needs a mask so as not to infect the healthy.

To protect yourself from possible ailments transmitted by airborne droplets, you need to buy respirators.

At the same time, in the Russian Federation, basically, only 2 respirators have been tested for bacteriological protection, these are 9332 from 3M (3M - Three M) and Alina-200AVK from the Respiratory Complex. Both of them are quite expensive nowadays, and cost about 1100-1500. At the same time, Alina is cheaper, 9332 is more expensive. Although they are considered disposable, with proper care, operation, cleaning, and storage, for example, 9332 can live and protect up to 3-4 weeks.

Respirators should not be looked at in pharmacies, and masks, by the way, too ... And those who are engaged in workwear, because this is their original field of activity, and even pharmacies buy masks from such suppliers in most cases, because these are not medical products.

Instead of going to pharmacies and tormenting poor pharmacists with your questions, call the work wear.

By the way, respirators are divided according to the degree of protection on ffp1 ( up to 4 MPC), ffp2 (up to 12 MPC), ffp3 (up to 50 MPC).

It is believed that the 1st class of protection provides protection against viruses and bacteria by 86%, the second class by 96%, and 99% class 3.

By the way, we have a bulk (available) of all this (respirators, medical masks, respiratory protection, antiseptics), however, unfortunately, they are expensive - http://prof-kom.ru/category/sredstva-zashchity/organov-dykhaniya/respiratory_1/

It depends on who to wear it. A mask is put on a sick person, and if everyone puts it on in the subway or on the street, then it will not save you from infection. The fact is that the mask does not interfere with the penetration of viruses, since viral particles are very small, and they, of course, can penetrate through the mask and in general through anything. The mask is designed to prevent the spread of phlegm particles that fly off when you cough and sneeze. Based on this, the mask should be worn on the sick person, or, in extreme cases, on the person who has direct contact with the sick person. The general wearing of masks, which I call a Chinese flash mob, does not make much sense in public places. If you don't want to get infected, avoid crowded places, do not contact sick people, and there is no point in wearing a mask just like that.

This is one of the protection measures, mechanical protection, masks need to be changed every two hours. And besides masks, there are many other measures that save you from influenza.

Masks are a filter, flu is transmitted by airborne droplets most often, someone sneezed - the drops fly, get on your mucous membrane, and the virus looking for where to settle down in a new place. And the mask protects the respiratory organs from the ingress of such viruses. But this is not a panacea.

The source of the infection should wear a mask so that when you breathe out and sneeze, the bacteria do not scatter strongly around. For a healthy person, a mask is useless.
