CHAPEL HILL, NC - A study published today in
JAMA Internal Medicine shows that wearing two face coverings can nearly double the effectiveness of filtering out SARS-CoV-2-sized particles, preventing them from reaching the wearer s nose and mouth and causing COVID-19. The reason for the enhanced filtration isn t so much adding layers of cloth, but eliminating any gaps or poor-fitting areas of a mask. The medical procedure masks are designed to have very good filtration potential based on their material, but the way they fit our faces isn t perfect, said Emily Sickbert-Bennett, PhD, associate professor of infectious diseases at the UNC School of Medicine and lead author of the study.
