手部衛生是感染控制的第一道防線。正確的洗手方式包含使用肥皂與流水並至少摩擦 20 秒。然而，含酒精乾洗手（Hand sanitizer）對於帶有芽孢的細菌（如艱難梭菌 C. difficile）無效，因為酒精無法殺死芽孢，必須透過流水的機械性沖洗才能有效移除。護理師應針對此種特殊病原菌的特性進行嚴格衛教。
Hand hygiene is the first line of defense in infection control. Proper handwashing technique includes using soap and running water with friction for at least 20 seconds. However, alcohol-based hand sanitizer is ineffective against spore-forming bacteria such as Clostridioides difficile because alcohol cannot kill spores; only the mechanical action of running water can effectively remove them. The nurse should provide strict education on this particular pathogen's characteristics.
