FRIDAY, Jan. 14, 2022 (HealthDay News) — Experience masks are touted as a essential instrument in protecting against the spread of COVID-19, and a new examine presents more proof that they work.

“The investigate gives very clear evidence and recommendations that three toes of distancing with face coverings is better than 6 feet of distancing without the need of face coverings,” claimed research co-author Kareem Ahmed. He is an affiliate professor in the College of Central Florida office of mechanical and aerospace engineering.
