Mask-wearing involves using a covering over the nose and mouth to reduce the spread of germs and protect against airborne particles. This practice became especially important during the COVID-19 pandemic, as it helps prevent the transmission of the virus from person to person. Masks can be made from various materials, including cloth, surgical fabric, or specialized filters. In addition to health benefits, mask-wearing can also promote social responsibility and community safety. Many public places, such as hospitals, schools, and public transportation, have implemented mask mandates to protect vulnerable populations. Wearing a mask is a simple action that can contribute to overall public health efforts.
