An article in Prevention featured John Sellick discussing how facemasks protect those wearing them, as well as other people. “There’s plenty of good data to support this,” says Sellick. He adds, "It’s never going to provide 100% protection. But the more people who are wearing masks to prevent the virus from escaping, the less pressure it puts on everyone else’s mask to filter things.”
