Wearing a mask is an important protective measure to prevent respiratory infectious diseases, which can reduce the risk of novel coronavirus infection. The mask can not only prevent patients from spraying droplets, reduce the number and spraying speed of droplets, but also block droplet nuclei containing viruses and prevent the wearer from inhaling.
Some people wear a mask for two or three days, especially the older generation always think that changing a mask is too wasteful, and simply wear a mask repeatedly. In this case, the mask will be contaminated by some dust, bacteria, water vapor and saliva. If it is not replaced frequently, these residual bacteria and viruses will not only fail to protect, but may also be counterproductive.
The correct way to wear a mask
1, Clean your hands: Pay attention to hand hygiene every day, and wash your hands when wearing and taking off a mask.
2. Distinguish right from wrong: Before wearing the mask, please put the nose clip side of the mask upward and the dark side outward. If the mask has no color difference, it can be judged by the folds of the mask that the folds are downward.
3. Close fitting: When wearing the mask, put your fingers in the middle of the metal nose clip and press inward at the same time, and move your fingertips along both sides of the nose clip until the nose clip completely fits the nose and the mask completely fits the face without leaving gaps. Breathe in quickly at the same time, check whether the air leaks from the edge of the mask, including the bridge of the nose, and then adjust the nose clip.
