手部衛生（Hand hygiene）是預防醫院感染（Healthcare-associated infections, HAIs）最簡單且有效的措施。根據疾病管制與預防中心（CDC）標準，洗手時間需至少 20 秒，透過肥皂與水的機械性摩擦移除病原體。洗手應在接觸病人間隙、執行無菌技術前及接觸體液後嚴格執行，而非僅在肉眼可見髒污時才進行。
Hand hygiene is the most effective method for preventing healthcare-associated infections. According to CDC guidelines, hands should be washed with soap and water for at least 20 seconds to mechanically remove pathogens. This practice is required before and after patient contact, regardless of visible dirt, and paper towels are preferred over air dryers for drying.
