洗手技術關鍵在於物理性摩擦帶走菌落。WHO 指南建議手部洗滌時間至少 15-20 秒。熱水（A）易損傷皮膚屏障，應使用溫水；關閉水龍頭（B）需使用紙巾，避免再次污染；擦手方向（D）應由手部向手腕擦拭，避免水滴回流污染。正確摩擦過程涵蓋手背、指縫與指甲縫。
Correct hand hygiene relies on mechanical friction to remove microorganisms, with WHO guidelines recommending washing for at least 15 to 20 seconds. Using hot water can damage the skin barrier, and touching the faucet with bare hands after washing re-contaminates clean hands; therefore, paper towels should be used to turn off the faucet.
