ROCHESTER, N.Y.(WHEC)— Here's a Fact Check follow up.
The Centers for Disease Control and Prevention may soon officially recommend wearing two masks to help stop the more contagious variants of COVID from spreading. Dr. Anthony Fauci says the guidance would call for people to double up.
Last week we did a fact check to see if wearing multiple masks is more effective, as researchers at Virginia Tech found one cloth mask blocks 50% of particles, two can get that number up to 75%.
A three-layer mask can stop up to 90%.
