Face shields offer more effective protection against coronavirus than masks and should be worn by the public whenever they leave home, according to US physician and epidemiologist Michael Edmond. Edmond, an infectious diseases physician and hospital epidemiologist in Iowa City, USA, has been advocating the use of face shields on his blog. He believes the simple devices are more effective than masks at protecting the eyes, nose and mouth from Covid-19 infection and praised efforts by architects and designers to manufacture the devices as “one of the silver linings of this pandemic”.<\/p>\n\n\n\n
They provide better facial protection than masks, Edmond believes, as well as being reusable and more comfortable.<\/p>\n\n\n\n
