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.
