1 expert favors shields for general public
The shields, already worn by some medical professionals, could be as effective as cloth masks in preventing the spread of covid-19.
“I think face shields are probably a superior solution rather than face masks for the general public,” said Dr. Amesh Adalja, a Pittsburgh-based infectious disease and critical care physician.
So far, the shields are not recommended for use by the general population, according to the Centers for Disease Control and Prevention. The shields can be worn like hats, with a piece of plastic that covers all or most of the face.
“CDC does not recommend use of face shields for normal everyday activities or as a substitute for cloth face coverings,” the federal agency advises on its website. “It is not known if face shields provide any benefit as source control to protect others from the spray of respiratory particles.”
Face shields could be easier for people to properly wear to prevent spreading the virus to others, Adalja said.
Wearing shields also prevents people from touching their face, he said.
Face shields also protect the eyes, something face masks can’t do at all, Drombosky pointed out.
“Face shields protect your eyes from aerosol particles in most scenarios,” he said. “The big thing with face shields is there’s a lot of ways to manufacture them.”
