The plates were then tested and found to contain 18 to 60 colonies of bacteria each, although harmless laboratory bacteria were used for the test.

This sends faecal particles into the air, where they linger until you turn on the hand dryer. Either way, they note in the paper that "paper towel dispensers have recently been added to all 36 bathrooms in basic science research areas in the UConn School of Medicine surveyed in the current study".

The results of the study were concerning.

Researchers in CT say using hand dryers can blow bacteria throughout bathroom surfaces and your hands.

Study authors said Clostridium difficile, a serious illness that causes diarrhea, also could be spread through the hand dryers.

The hand dryers were apparently sucking up the bacteria around the bathroom and blasting them to the hands of people. Spore-forming colonies, identified as B. subtilis PS533 averaged ∼2.5-5% of bacteria deposited by hand dryers throughout basic research areas examined regardless of distance from the spore forming laboratory, and these were nearly certainly deposited as spores.

Hand dryers suck up bathroom air and spew it out at speed.

According to a new study conducted at the University of CT, electric hand dryers actually spread fecal matter in public restrooms.

Alternatively paper towels are found to be more hygienic, but that option is also less environmentally friendly and potentially more costly. Regular and thorough washing of hands remains one of the most effective ways of staying healthy, no matter how you choose to dry them afterward.
