— Explanation · 中文詳解 —
艱難梭菌（C. difficile）具有強大的孢子形成能力，這些孢子對酒精具有高度抗性。一般酒精類乾洗手液（Alcohol-based hand rubs）無法有效去除孢子，僅能透過機械性摩擦與肥皂水的清洗才能將其從手上移除。因此，針對此類感染病人，標準預防措施為接觸隔離（Contact Precautions），且洗手必須使用肥皂與水。
Clostridium difficile spores are resistant to alcohol-based hand sanitizers, making mechanical removal with soap and water essential for infection control. Contact precautions are required, but hand hygiene must specifically involve washing with soap and water to effectively eliminate spores and prevent cross-contamination.
