Hand dryers worse than paper towels for spreading germs

in science on (#PBJR)
Researchers have discovered that when hands are poorly washed airborne germ counts are 27 times higher around air dryers in comparison with the air around paper towel dispensers. This shows that both jet and warm air hand dryers spread bacteria into the air and onto users and those nearby. "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.

Researchers 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) collected more than five minutes after drying ended and still detected in the air 15 minutes after hand drying.

That is a great idea; Of course it would go without saying that Australians would probably have pub-science down pat :) When I can, I use my used paper towels to grab the door handle, and hope they put a trashcan close by.
