An Yi citizen in Xi 'an was infected with a mouthful of sputum without wearing a mask. What are the importance of wearing a mask?

First of all, wearing a mask correctly is the simplest and most effective measure to effectively reduce the risk of transmission, prevent the spread of the epidemic and ensure health. Emergency headquarters, the city's epidemic prevention and control, once again reminded the general public: In order to ensure public health and personal protection, please remember to wear masks when going out! Everyone is the first person responsible for his health. To develop the good habit of carrying a mask with you, always remember the main points of wearing: distinguish between inside and outside, cover your mouth, nose and jaw, adjust and press the metal strip, and change the mask regularly and timely? . If the mask is dirty, deformed, damaged or smelly, it needs to be replaced in time. Don't throw away the mask after use, and handle it according to the classification requirements of domestic waste.

Secondly, it can reduce the risk of novel coronavirus infection. Because one of the transmission routes in novel coronavirus is droplet transmission, the mask can not only prevent the virus carriers from spraying droplets, reduce the number and speed of droplets, but also block the droplet nuclei containing the virus and prevent the wearer from inhaling. Note: Wearing a mask is an effective measure to prevent novel coronavirus. We should not be lucky. When necessary, we must wear masks when we go out.

Furthermore, people who wear masks protect themselves, and people who don't wear masks protect themselves. Because more people wear masks, the spread of the virus will obviously slow down or even stop. In this case, we all wear masks at the same time, and with the strong vaccine barrier of the whole people, the virus cannot invade. I believe that with our joint efforts, the epidemic will eventually be defeated! Proper use, storage and cleaning of masks are the key to maintain their effectiveness.

The outer layer of the mask usually accumulates a lot of dirt such as dust and bacteria in the outside air, while the inner layer blocks exhaled bacteria and saliva. Therefore, you can't use both sides alternately, otherwise the pollution and dirt on the outer layer will be directly inhaled into the human body close to the face and become the source of infection. When not wearing a mask, the mask should be folded into a clean envelope, and the side close to the nose and mouth should be folded inward. Don't put it in your pocket or around your neck.
