困難梭狀桿菌（C. difficile）感染的病人會排出具有高度傳染性的孢子（Spores）。這類孢子對大多數酒精乾洗手液具有抗性，因此「肥皂與流水洗手」是唯一能透過物理摩擦與沖洗將孢子移除的方法。酒精性乾洗手液無法殺滅孢子，反而可能造成擴散。這是接觸隔離（Contact precaution）中最核心的護理要求。
Clostridium difficile spores are resistant to alcohol-based hand sanitizers. Therefore, washing hands with soap and water is the most critical precaution, as the mechanical action of friction and rinsing is necessary to physically remove the spores from the skin.
