Which sequence correctly describes proper handwashing?

• A. Wet, apply soap, scrub at least 20 seconds, rinse, dry
• B. Wet hands briefly and rinse
• C. Rinse, soap, scrub 5 seconds, dry
• D. Dry hands before wetting

Answer: (A)

Effective handwashing relies on a clear sequence that uses soap and enough mechanical action to lift and remove germs from all hand surfaces. Start by wetting your hands with clean running water to help soap spread and loosen dirt. Next, apply soap to create a good lather that can carry away microbes. Then scrub all areas of the hands for at least 20 seconds—covering palms, backs of the hands, between the fingers, under the nails, and the wrists—so the brushing action physically dislodges germs. Rinse thoroughly under running water to wash away the loosened microorganisms and soap. Finally, dry hands with a clean towel or air dry, and if possible use the towel to turn off the faucet to avoid recontamination. Skipping soap, shortening the scrubbing time, reversing the order, or drying before wetting would reduce the effectiveness of the hand hygiene.
