Can we use a face shield (protective shield) instead of a classic mask? Does the face shield replace the mask?

Answer is no.

Because health authorities do not recommend the use of transparent plastic visors instead of masks on the grounds that research on whether an infected person (caught in Covid-19) prevents spreading virus droplets to others is still inadequate.

However, those who want additional protection can wear a face shield in addition to the mask.

Christopher Sulmonte, from the Johns Hopkins Hospital biocontrol unit, states that besides protecting the eyes, face shields have the added benefit of deterring people from touching their face as a physical barrier.

Meanwhile, according to the US Center for Disease Control and Prevention (CDC), studies so far show that the best trench is with a hood (hood) at the top, or trenches designed to cover the sides and bottom of the face to prevent the spread of the virus.

This is cited as the trenches leave less room for droplets from sneezing, coughing, and speech to spread.

On the other hand, CDC states that when you wear a reusable face shield in addition to the mask, you should definitely clean it after each use.

Also, the soot advises that you should wash your hands before and after removing the visor.
