In the News: Dr. Sara Zimmer Talks COVID-19 and Face Masks

An expert in microbiology, Biomedical Sciences faculty member, Dr. Sara Zimmer speaks to Fox 21 News about how and when to wear face masks amid the COVID-19 pandemic.
 
“If the air is escaping out of the sides and the top and bottom, then it’s not as effective and we want our masks to be as effective as possible," Dr. Zimmer says. "So maybe even more important as how many times has my mask been used, or how clean it is? Does it fit my face properly?"
