If everyone wears a mask, 58% of Covid-19 deaths could be prevented by fall, study says

A new projection from the University of Washington found that at the current rate, the U.S. could reach 100,000 Covid-19 infections a day by late September, topping out at nearly 168,000 projected new infections on a single day on Nov. 1. But if 95% of people wear a face mask, it could prevent tens of thousands of those infections and more 45,000 total deaths between now and November. "It is hard to imagine any health intervention that would be more cost-effective," says professor Theo Vos.
