Is it true？／You don’t say. Dry cell phones carry bacteria and are at risk of infectious diseases.

　　Cctv news"Wash your hands before and after meals" is a well-known health habit. In restaurants, shopping malls and other places, people often use hand dryers to dry their hands. Recently, however, researchers from Europe have tested hand dryers in three hospitals. They found that this machine, which seems to blow-dry hands and kill bacteria, turned out to be the chief culprit in spreading bacteria.

　　This is a photo of a hand-dried cell phone irradiated by ultraviolet light. It can be seen that bacteria are everywhere inside the hand-dried cell phone and even spread to the wall. The researchers said that, by comparison, the number of bacteria in toilets using hand dryers was three times higher than those using paper towels.

　　A reporter from British Sky News used a special ultraviolet lamp to test the bacteria near the hand dryer.

　　A professor from the University of Leeds in the United Kingdom said that once people touch dry cell phones with bacteria, they are at risk of catching diseases.

　　The researchers suggest that after washing hands, drying hands with paper towels can reduce the spread of bacteria and reduce the possibility of cross-infection.
