The CDC says there are two ways to significantly reduce your risk of getting COVID-19, and both involve wearing a mask.
Studies show wearing two masks and making sure your mask fits properly reduce exposure.
One study found wearing two masks blocked 92.5% of cough particles, as opposed to one mask that blocked less than 50%.
Another experiment looked at the spread of COVID during breathing, when two people were double-masked or wearing snug-fitting masks.
It found their exposure was reduced up to 96%.
