woman in blue and white stripe shirt washing her hands

This young girl was shown in the process of properly washing her hands at her kitchen sink, briskly rubbing her soapy hands together under fresh running tap water, in order to remove germs, and contaminants, thereby, reducing the spread of pathogens, and her ingestion of environmental chemicals or toxins. Children are taught to recite the Happy Birthday song, during hand washing, allotting enough time to completely clean their hands.
