Members of the public could be putting themselves more at risk from contracting coronavirus by wearing face masks, one of England’s most senior doctors has warned.
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.
Asked about their effectiveness, Dr Harries told BBC News: “What tends to happen is people will have one mask. They won’t wear it all the time, they will take it off when they get home, they will put it down on a surface they haven’t cleaned.
