Face masks are protective coverings worn over the nose and mouth. They help prevent the spread of germs, especially during illnesses like the flu or COVID-19. By blocking respiratory droplets, face masks can keep both the wearer and others safe. They come in various types, including surgical masks, N95 respirators, and cloth masks, each offering different levels of protection. Wearing a face mask is a simple yet effective way to contribute to public health. Many people wear them in crowded places, such as public transport or grocery stores, to reduce the risk of transmitting infections. It's a small action that can make a big difference in keeping communities healthy.
