Using an ultraviolet cabinet improves compliance with the World Health Organization's hand hygiene recommendations by undergraduate medical students: a randomized controlled trial.

Background: Appropriate hand hygiene (HH) is key to reducing healthcare-acquired infections. The World Health Organization (WHO) recommends education and training to improve HH knowledge and compliance. Physicians are ranked among the worst of all healthcare workers for compliant handrubbing with its origin probably being the failure to learn this essential behavior during undergraduate medical studies.
