why is it safer to wear a mask in public?
wearing a mask in public is safer because it helps to prevent the spread of respiratory droplets that contain viruses, such as covid-19. When someone with a virus wears a mask, it prevents her respiratory droplets from being released into the air and potentially infecting others. Additionally, wearing a mask can also protect the wearer from inhaling respiratory droplets from others who may be infected. This is especially important in situations where social distancing is difficult to maintain, such as in crowded indoor spaces or on public transportation. Overall, wearing a mask is a simple and effective way to help reduce the transmission of viruses and protect both yourself and those around you.
