Which practice helps lower the risk of C. difficile infection?

• A. Proper handwashing and limiting the use of antibiotics helps lower the risk.
• B. Only using alcohol-based hand sanitizer.
• C. Avoiding all fruits and vegetables.
• D. Frequent antibiotic use.

Answer: (A)

Preventing C. difficile infection relies on two main actions: keeping hands clean with effective hand hygiene and using antibiotics only when truly needed. Soap and water handwashing physically removes C. difficile spores from the hands, which is crucial because these spores can survive on surfaces and are not reliably killed by alcohol-based sanitizers. Limiting unnecessary antibiotic use helps protect the normal gut bacteria that keep C. difficile in check; when antibiotics disrupt this balance, C. difficile can grow and cause infection. Using only alcohol-based hand sanitizer isn’t enough to remove spores, so it’s not the best sole practice for prevention. Avoiding fruits and vegetables isn’t related to C. difficile risk, and frequent antibiotic use actually increases the risk by disturbing gut flora.
