Myth: Wearing a mask means you don’t have to physically distance from other people

But while masks offer protection from the spread of the coronavirus, they are one tool among many that should be used together to lower spread. Masks protect you from other people’s respiratory droplets and keep your droplets away from others, but especially if you’re using cloth or surgical masks which don’t form a seal between the mask and your face, there’s the risk of some droplets containing the virus still getting around the mask. To protect yourself and others you should wear a mask and maintain six feet distance from others, and also wash your hands frequently and shelter-in-place in areas where virus spread is high. Everyone should wear a mask to protect themselves and others from COVID-19, only children younger than 2 years and some people with breathing problems should not wear masks.
