$MASKS

A mask is a protective covering worn over the nose and mouth to reduce the spread of airborne particles, particularly in medical or public health contexts. Masks can be made from various materials, such as cloth, surgical-grade fabric, or respirator-grade material (like N95). They are commonly used to prevent the transmission of infectious diseases, such as COVID-19, by trapping respiratory droplets released when a person talks, coughs, or sneezes. Masks are also used in various professions, such as healthcare, construction, and manufacturing, to protect workers from inhaling harmful substances.
