Escalator handrails

According to CBS News, escalator handrails, at least in malls, are dirty. The organization found traces of food, E. coli, urine, mucus, feces, and blood.

England's chief medical officer Professor Chris Whitty told the public not to touch their faces after touching a handrail, as there was "some risk of transmission."

Whitty told The Telegraph, "So, if you go on to the Tube and touch the rail, that's fine, but just be aware of what you do with your hands - don't touch your face, wash your hands, and then you can do what you like."
