More widespread wearing of face masks could prevent tens of thousands of deaths by COVID-19, epidemiologists and mathematicians project.

A model from the University of Washington's Institute for Health Metrics and Evaluation shows that near-universal wearing of cloth or homemade masks could prevent between 17,742 and 28,030 deaths across the US before Oct. 1.

A few months ago, it may have seemed silly to wear a face mask during a trip to the grocery store. And in fact, the mainline public health message in the U.S. from the Centers for Disease Control and Prevention has been that most people don't need to wear masks.

But as cases of the coronavirus have skyrocketed, there's new thinking about the benefits that masks could offer in slowing the spread. The CDC says it is now reviewing its policy and may be considering a recommendation to encourage broader use.
