Which hand hygiene method is preferred for Clostridioides difficile and scabies?

• A. Alcohol-based hand sanitizer
• B. Soap and water
• C. Antiseptic wipes only
• D. Hot water only

Answer: (B)

The main concept is that some pathogens require actual removal from the hands rather than just sanitizing, because they resist certain sanitizers. Clostridioides difficile forms spores that alcohol-based hand sanitizers don’t reliably kill, so hands must be washed with soap and water to physically remove these spores. Scabies mites reside on the skin and can be transferred by direct contact, and they’re not reliably eliminated by sanitizer either, so thorough handwashing with soap and water helps remove them. Soap and water also provides the mechanical action of scrubbing that helps detach dirt and organisms from the skin. Hot water alone won’t remove spores or mites without the soap and friction. Antiseptic wipes aren’t appropriate as the sole method for routine hand hygiene in these scenarios.
