Should we all wear masks?
Should we all wear masks? Professor Ian Fraser has the answer.
“The most useful place for a mask is on the face of somebody who is actually infected because it stops them spreading the infection to other people. If you think you might be infected, then wearing a mask is a good idea too, even if you're not actually infected. If you're not infected, then there is a shortage of masks and they are probably better worn by people who are working in close contact with people who are infected.”
