困難梭狀芽孢桿菌（C. difficile）會產生對環境極具抵抗力的芽孢，這些芽孢對酒精具有抗性。臨床上，酒精類手部清潔劑（Alcohol-based hand sanitizer）無法殺滅或移除這些芽孢，反而可能透過物理塗抹擴散芽孢。因此，接觸此類病人後，必須使用肥皂（Soap）與清水（Water）進行洗手，利用物理摩擦（Friction）將芽孢從皮膚表面有效沖洗掉，這是預防院內交叉感染的黃金標準。
Clostridioides difficile produces spores that are resistant to alcohol-based hand sanitizers, which may even spread them via friction. Soap and water mechanically remove these spores from the skin through physical washing, making it the most effective method for preventing transmission.
✦ 台美臨床差異
美國醫院對於 C. diff 病人嚴格執行肥皂洗手（Soap and water），酒精乾洗手液在病房門口通常會被暫時移除或貼上標示，以強制醫護人員使用洗手台。
