When you are wearing a face mask, it may be more difficult for you to recognize people, even if they are not wearing masks.
Positive messages about unity and togetherness are more effective at getting people to mask up and protect against COVID-19 than messages based on fear.
As more states are requiring people to wear face masks in public to prevent the spread of COVID-19, researchers investigate the best materials people can use to create their masks at home. A single layer of T-shirt fabric is 40% effective at higher droplet blocking. When layers are doubled, the fabric is 98% effective, exceeding the effectiveness of a clinical medical mask.
Wearing face masks significantly reduced the amounts of airborne virus particles expelled from infected patients. Findings suggest surgical-style face masks could slow the transmission of coronavirus and influenza viruses.
