Abstract

We compared the efficiency of paper, cloth, and electric warm air drying in eliminating rotaviruses and Escherichia coli remaining on finger pads washed with 70% isopropanol, a medicated liquid soap, an unmedicated liquid soap, or tap water alone. The contaminated area on the finger pads of a volunteer was exposed to the hand-washing agent for 10 seconds and then rinsed in 40 degrees C tap water. The washed areas were dried for 10 seconds by one of the three methods. Irrespective of the hand-washing agent used, electric air drying produced the highest and cloth drying the lowest reduction in the numbers of both test organisms. These findings indicate the importance of selecting the right means for drying washed hands, particularly when less effective hand-washing agents are used.
