Over the past few weeks, I have noticed that many people are now wearing face shields in shops, instead of a mask.
Look at the gap. Both under her chin, and at the sides, these shields allow any infection to spread easily as the wearer is breathing, coughing, or sneezing. In short, they do nothing to protect anyone.
Face shields are meant to be used as an additional safety measure, in conjunction with a proper mask.
So to all of you who are only wearing a face shield on its own, stop doing it. It will not properly protect you, or anyone you come into contact with.
