After the long Lunar New Year holidays, now children have started going back to school. This is also what makes parents very worried about the health of their children before the complicated development of the disease caused by corona virus. WHO and the Ministry of Health jointly recommend that one of the most effective ways to prevent disease is to simply wear a mask. However, not all mothers already know how to buy and use the right mask for their children.

It can be easily captured by conventional medical masks that effectively filter particles over 5 micrometers in size.
Therefore, it is only necessary to purchase a 3-layer nonwoven medical mask to prevent large droplets of virus containing saliva from being thrown from the sick person through sneezing or coughing.
Criteria for choosing standard medical masks for disease prevention
- Outer layer: Has water-repellent properties, usually light blue in color, effectively prevents liquid particles from splashing out when others sneeze, cough or breathe heavily.
- Inner layer: Always have white color that is easy to distinguish from the outer layer. This layer is made of fabric, which will contact the face when worn, so it must be smooth, lint-free or uncomfortable. In addition, the inner layer of the mask is water-absorbent to help absorb sweat, creating a comfortable wearing.
- Middle layer: It works to prevent droplets from splattering and filter dust, bacteria. This is the class that determines the quality of the mask. A "standard" filter layer must let the air easily pass through, creating ventilation for the user, but it must be structured enough to filter out tiny particles of dust and bacteria.
The recommendations of the World Health Organization on how to use standard medical masks to prevent viruses are as follows:
- Only use the mask once and then throw it in a safe, covered trash.

In addition, when handling and touching other objects, the virus can follow the secretions spreading out in the community.
Doctor Tran Vu Quang, Central Obstetrics and Gynecology Hospital (Hanoi), also said that influenza virus spreads from person to person through droplets released when a person with the flu coughs or sneezes. In some cases, the influenza virus can be spread when a person's hand touches contaminated or contaminated objects, the hand then touches the mouth and nose.
Our hands hold common items such as money, doorknobs, car rails, cups, dishes, chopsticks, shared spoons at restaurants, cafes ... and then directly hold food then put them in mouth, virus also enters the mouth as well.
Therefore, for respiratory-borne diseases, the World Health Organization recommends using masks and emphasizing proper hand washing before handling food or utensils into nose and mouth and not using hands or towels. dirty eye wipe.

Meanwhile, hand washing with soap or antiseptic solution has antibacterial effect, preventing infection.
