Turns out that masks may increase your risk of infection too!
'Jenny Harries, deputy chief medical officer, said the masks could “actually trap the virus” and cause the person wearing it to breathe it in.
'For the average member of the public walking down a street, it is not a good idea” to wear a face mask in the hope of preventing infection, she added.'
Oh wait, no that's from last March, obviously from a parallel universe...
