A face mask is a protective covering worn over the nose and mouth, typically made of fabric or disposable materials. It is designed to help prevent the spread of airborne particles, such as bacteria, viruses, and pollutants, thereby reducing the risk of respiratory infections and diseases. Face masks have become increasingly important in maintaining public health and safety, particularly during times of contagious outbreaks like COVID-19. The 😷 emoji is often used to symbolize wearing a face mask or to represent the concept of protection and caution.
