Which is ineffective against C. diff spores?

• A. Reverse Isolation
• B. Alcohol Based Hand Rub
• C. Biohazard Disposal
• D. Nosocomial Infection

Answer: (B)

Spore-forming organisms like C. difficile are unusually hardy and resist many common sanitizers. Alcohol-based hand rubs do not kill C. diff spores, so they’re ineffective for preventing transmission in this case. The safer approach is to wash hands with soap and water, which physically removes spores from the skin, and to use sporicidal cleaners (such as bleach-based products) for environmental disinfection. The other options relate to broader infection-control concepts rather than a method that effectively inactivates spores: reverse isolation protects the patient from others, biohazard disposal concerns safe handling of contaminated waste, and nosocomial infection describes infections acquired in a hospital. So the best choice highlights that alcohol-based hand rubs fail to inactivate C. diff spores.
