Hand dryers worse than paper towels for spreading germs

Scientists from the University of Leeds (UK) have discovered that airborne germ counts are 27 times higher around air dryers in comparison with the air around paper towel dispensers. Their study, published in theJournal of Hospital Infection, shows that both jet and warm air hand dryers spread bacteria into the air and onto users and those nearby.

To mimic hands that had been poorly washed, the research team contaminated the subjects’ hands with Lactobacillus , a harmless type of bacteria. The researchers then collected air samples around the hand dryers and also at distances of one and two meters away.

They found that air bacterial counts close to jet air dryers were 4.5 times higher than around warm air dryers and 27 times higher compared with the air when using paper towels. Next to the dryers, bacteria persisted in the air well beyond the 15 second hand-drying time, with approximately half (48 percent) of the Lactobacilli collected more than five minutes after drying ended. Lactobacilli were still detected in the air 15 minutes after hand drying.

“These findings are important for understanding the ways in which bacteria spread, with the potential to transmit illness and disease,” said Professor Mark Wilcox, who led the study. “Next time you dry your hands in a public toilet using an electric hand dryer, you may be spreading bacteria without knowing it. You may also be splattered with bugs from other people’s hands.”
