A face covering is a protective item worn over the whole face, or just the nose and mouth, to reduce the spread of germs, viruses, or other harmful particles. It can be made of cloth, paper, or other materials that cover the face. Face coverings are commonly used to prevent germs from being released into the air when breathing, talking, coughing, or sneezing. They are essential in situations where physical distancing may be challenging, such as during pandemics or in crowded spaces.
