Hand sanitation is defined as all actions aimed at cleaning hands. In connection with these activities, the sanitary hand consists of washing hands with soap and water and use antiseptic liquids without using water, and without drying action with a tool, which aims to reduce or suppress the growth of microorganisms.
Health and hand hygiene substantially reduces the number of microorganisms that cause disease in both hands and arms so as to minimize cross-contamination (eg from health workers to patients). From the viewpoint of infection prevention and health practices, sanitation is intended to prevent an infection transmitted through hand, by getting rid of dirt and dust as well as inhibit or kill microorganisms on the skin.
With hand sanitation can be eliminated not only the majority of organisms that are transmitted through contact with the patient and the environment, but also most of the organisms that live in the layers of the skin.
