A face mask is a protective covering worn over the nose and mouth. It is commonly made from fabric, paper, or other materials and is designed to reduce the spread of germs and protect the wearer from inhaling harmful particles. Face masks became widely used during the COVID-19 pandemic to help prevent the transmission of the virus, known as SARS-CoV-2. There are different types of face masks, including surgical masks and N95 respirators. Surgical masks are typically used in healthcare settings, while N95 respirators offer a higher level of filtration. Wearing a face mask is often recommended in crowded or enclosed spaces to enhance public health and safety.
