CDC hand washing recommendations specify washing for 20 seconds using which motion?

• A. Wash for 10 seconds with straight-line scrubbing.
• B. Wash for 60 seconds with various motions.
• C. Wash for 20 seconds with a downward circular motion.
• D. Wash for 5 seconds with minimal contact.

Answer: (C)

Effective handwashing hinges on enough contact time and thorough coverage. The recommended practice is to wash for about 20 seconds using a circular rubbing motion that covers all hand surfaces. The 20-second duration gives enough time for soap to lift germs, while the circular motions ensure you reach palms, backs of hands, between fingers, and under nails. Shorter times or improper motions leave areas untreated, and much longer times aren't necessary for CDC guidelines. The circular rubbing motion maximizes friction to dislodge microbes, making this the best choice.
