Shocking video proves face shields don't work to stop the spread of coronavirus

Face shields offer no protection against coronavirus if an infected person nearby sneezes without a mask on, a study shows. Researchers used computer models to visualise the spread of droplets around a face shield ejected by a human sneeze from 3ft (1m) away. It reveals'vortex rings' produced by the sneeze carry infectious particles to the face shield in less than a second and stick to the edges of the plastic. Researchers say if the timing of this wave of coronavirus particles coincides with the face shield wearer breathing in, the person can become infected. Wearing a face mask has a negative impact on our ability to communicate with others, according to a new survey.
