艱難梭菌（C. diff）感染的病人必須採取接觸隔離措施。最關鍵的預防手段是手部清潔，且必須使用「肥皂與流水」，因為艱難梭菌的芽孢具有抗酒精性，酒精乾洗手液無法殺滅芽孢。護理師在接觸病人後，必須確實執行肥皂洗手，以防交叉污染。口罩與負壓隔離室是針對呼吸道傳染病（如肺結核）的防護措施，不適用於腸道接觸傳染。
Clostridioides difficile forms spores that are resistant to alcohol-based hand sanitizers, making soap and water essential for effective removal through physical washing. Contact precautions are required, whereas negative pressure rooms and N95 respirators are reserved for airborne diseases like tuberculosis. Proper hand hygiene is the priority intervention to prevent cross-contamination.
