CDC recommends double masks to help protect against COVID-19

After months of demands for federal health officials to update mask recommendations, the Centers for Disease Control and Prevention announced new guidelines Wednesday that include wearing well-fitting face masks or two masks at a time to help curb the COVID-19 pandemic.

The updated guidance follows the release of new research from the CDC which tested various masks in a lab setting and found evidence that combining a cloth mask over a surgical mask could dramatically reduce both the spread of the virus to others and exposure to the virus oneself.

The CDC's new recommendations advise Americans to select masks with a nose wire that can be adjusted for a snug fit, and to use a mask fitter or brace to better seal their masks. The CDC also recommends wearing a mask with multiple layers for greater protection, or layering a cloth mask over a disposable medical mask.
