RESEARCH INDICATES SHIELDS ARE MORE EFFECTIVE THAN CLOTH MASKS
Reporting in the April 29, 2020 Journal of the American Medical Association, experts led by Dr. Eli Perencevich, of the university's department of internal medicine, and the Iowa City VA Health Care System... observed laboratory testing "suggests that cloth masks provide [only] some filtration of virus-sized aerosol particles." According to Perencevich's group, "face shields may provide a better option." The study noted, not only is "the use of a face shield a reminder to maintain social distancing,but it allows visibility of facial expressions and lip movements for speech perception."
