Why are alcohol-based hand sanitizers not effective against Clostridium difficile, and what should be used instead?

Alcohol-based hand sanitizers are not effective against Clostridium difficile because C. difficile bacteria produce spores that can remain on surfaces for a long time, and alcohol-based hand rubs do not destroy these spores. Instead, you should wash your hands with soap and warm water when caring for someone with C. difficile or when exposure to the organism is suspected or proven.

According to the text, Clostridium difficile bacteria produce spores that can stay on a surface for a long time. Alcohol-based hand sanitizers are not effective in destroying these spores. Therefore, when caring for individuals with C. difficile, it is important to wash hands with soap and warm water. The rules of hand hygiene also specify washing with soap and water if exposure to Clostridium difficile is suspected or proven, rather than using an alcohol-based hand rub.
