Face coverings limit the volume and travel distance of expiratory droplets dispersed when talking, breathing, and coughing. A face covering without vents or holes will also filter out particles containing the virus from inhaled and exhaled air, reducing the chances of infection.
High-quality face coverings can reduce the risk of the spread of infection because they cover the nose and mouth, reducing the spread of droplets and aerosols carrying coronavirus (COVID-19). This limits the amount of the virus being released when people talk and breathe.
You must follow some safety tips to protect yourself from the various types of infections:
• Before touching the mask, you must clean your hands with an alcohol-based hand rub or soap and water.
• You should inspect the mask for tears or holes, do not use a mask that is damaged.
• It is always advisable to adjust the mask to cover your mouth, nose, and chin, leaving no gaps on the sides.
• You must place the straps behind your head or ears. Do not cross the straps because this can cause gaps on the side of your face.
• You must avoid touching the mask while wearing it. If you touch it, clean your hands.
• Also, you must change your mask if it gets dirty or wet.
