"The researchers considered five scenarios for how the pandemic could play out with different levels of mask-wearing and rules about staying home and social distancing. All the scenarios assumed that no vaccine was available, nor any medicines capable of curing the disease.
Consistently, the most effective " not to mention cheapest and easiest " way to reduce deaths was to increase the number of people wearing masks.
As of Sept. 21, only 49% of Americans said they "always" wore a mask in public, according to the study. If U.S. residents do not mask up in increasing numbers, they risk another round of mandatory social distancing measures that could shut businesses and schools around the country, the authors said.
"The potential lifesaving benefit of increasing mask use in the coming fall and winter cannot be overstated," wrote the team from the Institute for Health Metrics and Evaluation at the University of Washington.
The forecasts also suggest that if states continue to ease their social distancing mandates and other restrictions despite the recent rise in COVID-19 cases, there could be more than 1 million deaths in the U.S. by the end of February."
