Correct wearing method of medical mask

The correct way to wear a medical surgical mask is as follows: (1) Nose clip side up, dark face outward (or folded down) (2) Pull the fold up and down to make the mask cover the mouth, nose and jaw. (3) The fingertips of both hands slowly press inward from the middle to both sides along the metal strip of the bridge of the nose until they are close to the bridge of the nose. (4) Adjust the mask properly so that the periphery of the mask fits the face completely. Disposable medical masks are recommended to be replaced every 4 hours; The recommended use time of N95 medical protective mask is 6-8 hours. Don't touch the outside of the mask when changing it, just take it off your ear. Be careful not to touch the front of the mask. Hold the strap with your hand and throw it into the garbage bag. After taking off the mask, wash your hands immediately and pay attention to hand hygiene. If the mask is wet or comes into contact with secretions, it should be replaced in time.
