People should definitely wear one mask, but double masking improves fit, Dr. Anthony Fauci, director of the US National Institute of Allergy and Infectious Diseases, told NBC’s Savannah Guthrie on the Today show on Thursday.
The CDC on Wednesday released new data that showed layering a cloth mask over a medical procedural mask could block 92.5% of potentially infectious particles by creating a tighter fit and eliminating leakage.
“At a minimum, wear a mask,” Fauci said. “This is what [the CDC] are saying, make sure you wear a mask. So you wear a mask, then you want it to fit better. So, one of the ways you could do it, if you would like to, is put a cloth mask over.”
He demonstrated how this works by putting two masks on himself and showing the places where two masks help better prevent leakage, and he told Guthrie that he, on occasion, has double masked.
“One mask at least, but if you want to really be sure, get a tighter fit with a second mask.”
