Wear a mask when you’re in public to help slow the spread of COVID-19. When selecting a mask, you have many choices. Avoid masks that are made of materials that make it too hard to breathe. Also avoid masks with valves or vents that allow virus particles to escape and masks that should be saved for healthcare workers. Wear cloth masks with two or more layers to help protect yourself and others from COVID-19. Learn more about the do’s and don’ts of masking: https://bit.ly/30QOzQF. | CDC
