If 95% of Americans wore masks in public, more than 100,000 lives could be saved from COVID-19 through February, a new modeling study suggests, according to a report by KCRA 3 News.

The study — from the COVID-19 forecasting team at the University of Washington's Institute for Health Metrics and Evaluation — notes that as of Sept. 21, only about 49% of U.S. residents reported that they "always" wear a mask in public.

If mask-wearing remains 49% through February and states continue with removing social-distancing mandates, the COVID-19 death toll across the United States could reach about 1 million deaths by Feb. 28, according to the study, published in the journal Nature Medicine.

Under the assumption that states shut down when their daily death rate exceeds eight deaths per 1 million people but mask-wearing doesn't change, the study's model projections forecast the death toll could reach 511,373 deaths by Feb. 28.

The scenario that 95% of people in each state wear masks — in addition to states reinstating social-distancing mandates if their daily death rates exceed exceed deaths per 1 million people — resulted in the lowest death toll projection, with 381,798 deaths by Feb. 28, according to the study.

For the study, the researchers analyzed data on COVID-19 cases and deaths in the United States from Feb. 1 through Sept. 21. That analysis — along with other factors, such as pneumonia seasonality, testing rates and mask use — helped inform model projections for the course of the pandemic through Feb. 28.
