PROVO, Utah — Four faculty members from BYU have reviewed dozens of studies on the use of face masks to slow the spread of COVID-19.

Their conclusion? Masks work.

Brigham Young University’s Benjamin Abbott and three others reviewed 115 published studies and articles on the use of face masks, and concluded that “masks could be one of the most powerful and cost-effective tools to stop COVID-19 and accelerate economic recovery.”

The BYU faculty members looked at the potential health effects of wearing masks and determined that only a few people have conditions that would make wearing masks a bad idea, with almost no evidence to support a lack of oxygen or a buildup of carbon dioxide.

The study is available on the BYU website.


How To Prevent the Spread of COVID-19 Coronavirus

COVID-19 coronavirus spreads person to person, similar to the common cold and the flu. So, to prevent it from spreading:

 

    • Wash hands frequently and thoroughly, with soap and water, for at least 20 seconds.

     

    • Don’t touch your face.

     

    • Keep children and those with compromised immune systems away from someone who is coughing or sneezing (in this instance, at least six feet)

     

    • If there is an outbreak near you, practice social distancing (stay at home, instead of going to the movies, sports events, or other activities.)

     

  • Get a flu shot.
