手看着干净，也可能带有病原微生物。对普通成年人来说，把洗手放在合适的时刻，并认真洗到每个部位，就是一项实用的日常防护。
什么时候洗？准备食物前、吃东西前、如厕后，咳嗽、打喷嚏或擤鼻涕后，以及手上有明显污物时，都应做好手卫生。不要只凭“看起来不脏”来决定。
一次洗手，可以按三个环节记：
一、先打湿，再涂皂。用流动水湿润双手，抹上肥皂或洗手液，涂匀双手各处。
二、仔细揉搓，不漏角落。掌心、手背、指缝、指背、大拇指和指尖都要洗到；一只手握住另一只手的大拇指转动揉搓，再把并拢的指尖放在另一手掌中揉搓，两手交换。
三、冲净并擦干。用流动水冲去泡沫，再用干净毛巾或一次性纸巾擦干，避免共用毛巾。
虚构生活例子：午餐前，小周走进洗手间，原本只想把手伸到水龙头下冲一冲。他想起还有指缝和大拇指没顾到，便用洗手液认真揉搓，冲净、擦干后再去吃饭。这个例子只演示操作，不代表真实人物或健康效果证明。
手上有明显污物时，应使用肥皂或洗手液和水洗净。

Remember These Steps to Wash Your Hands Thoroughly
Even hands that look clean may carry disease-causing microorganisms. For adults in general, washing at the right times and carefully cleaning every part of the hands is a practical form of everyday protection.
When should you wash? Practice hand hygiene before preparing food, before eating, after using the toilet, after coughing, sneezing or blowing your nose, and whenever your hands are visibly dirty. Do not decide solely on the basis that they “do not look dirty.”
You can remember a handwash in three stages:
1. Wet your hands first, then apply soap. Wet both hands under running water, apply bar soap or liquid hand soap, and spread it over every part of both hands.
2. Rub carefully, without missing any areas. Wash your palms, the backs of your hands, between your fingers, the backs of your fingers, your thumbs and your fingertips. Grasp the thumb of one hand with the other hand and rub it with a rotating motion, then bring your fingertips together and rub them in the palm of the other hand. Switch hands.
3. Rinse and dry. Rinse off the lather under running water, then dry your hands with a clean towel or a disposable paper towel. Avoid sharing towels.
A fictional everyday example: Before lunch, Xiao Zhou went into the restroom, originally intending only to hold his hands under the tap for a quick rinse. Remembering that he had not cleaned between his fingers or around his thumbs, he rubbed his hands carefully with liquid hand soap, then rinsed and dried them before going to eat. This example only demonstrates the procedure; it does not represent a real person or provide evidence of health benefits.
When your hands are visibly dirty, wash them clean with bar soap or liquid hand soap and water.
