Arthur Gran, M.D., of Troy Infectious Disease, a practice of St. Peter’s Health Partners Medical Associates, appeared on WNYT to discuss the efficacy of face shields in preventing the spread of COVID-19 and other viruses.
From the story:
As he explains, while the shield protects you from a face full of germs, if someone coughs or sneezes on you, the protection doesn’t last. That’s because of how the virus acts in the air.
“You have viral particles that are circulating throughout the air in droplets, that once they’re in the room, and they’re just moving around the room, that mask, that face shield loses its efficacy. So generally, face shields alone are not considered appropriate for preventing spread of viral illnesses during the time of patient care. For example, doctors are expected to wear both masks and face shields,” said Dr. Gran.
