In this study, published in the Journal of Hospital Infection, they swabbed the faces of 408 hospital staff with and without facial hair.
They had good reasons for doing so. We know that hospital-acquired infections are a major cause of disease and death in hospitals, with many patients acquiring an infection they didn't have when they went in. Hands, white coats, ties and equipment have all been blamed, but what about beards?
Well, the researchers were surprised to find that it was the clean-shaven staff, and not the beardies, who were more likely to be carrying something unpleasant on their faces.
The beardless group were more than three times as likely to be harbouring a species known as methicillin-resistant staph aureus on their freshly shaven cheeks. MRSA is a particularly common and troublesome source of hospital-acquired infections because it is resistant to so many of our current antibiotics.
