Does wearing two masks provide more protection?

It depends, but it’s possible that doubling up could help in some situations.

The U.S. Centers for Disease Control and Prevention recommends wearing a cloth mask made with two or more layers, and ensuring it covers your nose and mouth. The agency says it should fit snugly so there aren't any gaps at the sides of your face.

Wearing just one mask should be enough for most situations, as long as it fits well and isn't loose, said Dr. David Hamer, an infectious disease expert at Boston University.

“Starting out with a good mask to begin with is going to be key,” Hamer said.

Still, some people might want extra protection if they're at risk for severe illness if infected or will be in situations where they expect to be around others for extended periods, such as on a plane.

One option in scenarios when you want extra protection is to wear a cloth mask as well as a regular surgical mask, said Dr. Monica Gandhi, an infectious disease expert at the University of California, San Francisco.

Gandhi said that combination -- with either mask on top -- could help achieve a similar effect as the N95 mask. She recommended the added protection for people who will be indoors in areas where transmission rates are high — which could reflect the circulation of more contagious variants.

Another option Gandhi and a colleague recommend for situations where you want “maximum” protection: A two-layer cloth mask that has a filter material in between.

With single cloth masks for everyday use, Gandhi noted it's important that they're made of tightly-woven material and have at least two layers, which creates “an obstacle course” that makes it harder for virus-carrying particles to break through.

Health Experts Warn Of Winter Surge As Covid Cases Rise
Health officials are warning of a grim winter as the Omicron variant of COVID-19 spreads rapidly across the country. New York City is the latest hotspot, with cases rising in a way the city hasn't previously seen in the pandemic. Dr. Bob Lahita, director of the Institute for Autoimmune and Rheumatic Diseases at St. Joseph Health and author of the book "Immunity Strong," joined Cheddar to discuss whether the rest of the country will follow in New York's footsteps.
Covid Cases On the Rise As Holidays Near
Covid cases and deaths are on the rise in many parts of the country even before the Omicron variant takes hold. More than 30 states had higher seven-day averages for new cases last week than they did before Thanksgiving, according to Johns Hopkins University data, with some of the biggest increases in the Northeast. Dr. Anthony Santella, professor of Health Administration and University COVID Coordinator at the University of New Haven, joined Cheddar to discuss where we stand in the pandemic and how we can keep ourselves safe during the holidays.
