The Centers for Disease Control and Prevention has revised its guidance on mask-wearing during the coronavirus pandemic.
Before this latest update, the CDC said masks prevented those infected from transmitting the virus to healthy people.
The CDC called it “source control" when a mask blocks the virus, and a system of “filtration for personal protection," CNN reported.
Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, likened it to a two-way street.
“You protect others, their mask protects you, and your mask also protects you,” Fauci said in an interview with MSNBC.
The CDC said it lowered the risk of virus transmission by more than 70%.
The CDC says anyone over the age of 2 should wear a mask in public unless they have breathing issues or are “unconscious, incapacitated, or otherwise unable to remove the mask without assistance.”
