Reduction of microbial transmission in childcare using an improved hand drying protocol

This study was designed to compare bacterial transfer by touch contact in a childcare setting after participants used their usual hand drying procedure or a prescribed dual hand drying system. Eleven children washed and dried their hands using bathroom facilities provided by the childcare centre. On completion of each hand hygiene episode, the child handled an item representing food, skin or a toy. The same procedure was carried out on a further occasion but in this case, after washing, the children dried their hands using a retractable cloth towel and a warm air towel before handling the item. Asubstantial reduction in the touch transfer of microorganisims was achieved when the dual hand drying system was used. Bacterial numbers translocating to skin, food or a toy were reduced by 82, 84 and 96%, respectively, when the dual hand drying system replaced the child's usual routine. Children between the ages of 3 and 4 years can be trained to use a prescribed hand hygiene procedure that markedly reduces bacterial transmission by touch contact.
