Prevention in novel coronavirus:
How to choose a mask: You can choose a disposable surgical mask or N95 mask.
How to wear a mask: wash your hands before wearing, check the integrity of the mask, read the instructions and production date, and distinguish the front and back of the mask from top to bottom. After putting on the mouth, adjust the tightness of the belt and the shape of the nose clip. Under the premise of not causing discomfort to the head and face, pull the bandage to the tightest, and press the metal plates on both sides of the bridge of the nose with both hands to make it conform to the face. After the adjustment, you can use the following methods to test whether it is suitable to wear: bend your fingers slightly and close them, buckle them on the left and right sides of the mask and take a deep breath. If the periphery of the mask is tightly sucked on the face, the tightness will be good. In the process, you can also cooperate with common actions such as turning your head, lowering your head and raising your head. If you wear glasses and there is fog on the lenses, then-you must not wear a mask.
