What are the basic steps in an infection control hand hygiene protocol?

• A. Wipe hands with a paper towel only
• B. Dry hands with a shared towel
• C. Wash for 15 seconds with cold water
• D. Use soap and water or alcohol-based sanitizer; wash for at least 20 seconds when hands are visibly dirty; dry thoroughly

Answer: (D)

Hand hygiene is the most important step to prevent infection spread. The correct approach reflects using either soap and water or an alcohol-based sanitizer, with proper technique, duration, and drying.

If hands are visibly dirty or contaminated, wash with soap and water, scrubbing all surfaces (including backs of hands, between fingers, and under nails) for at least 20 seconds, then rinse and dry thoroughly with a disposable towel. Drying completely helps remove remaining microbes and reduces transfer. When hands are not visibly dirty, an alcohol-based sanitizer can be used—apply enough to cover all surfaces and rub until completely dry.

These elements—cleaning action (soap and water or effective sanitizer), sufficient duration (about 20 seconds when hands are dirty), and thorough drying—are what make hand hygiene effective. Wiping with a paper towel alone, drying on a shared towel, or washing for only 15 seconds with cold water do not meet these standards and leave more opportunity for contamination.
