今天是全球洗手日（Global Handwashing Day），全球洗手日是促進用肥皂洗手公私夥伴組織（PPPHW）發起的，號召全世界各國從2008年起，每年10月15日開展用肥皂洗手活動。此前一份調查顯示，僅7%城市居民保持良好洗手習慣。實際生活中，有很多接觸細菌情境我們不知：每次進餐、如廁、接觸錢幣等情境下都要洗手；洗手時要使用流動水；洗手時要使用肥皂、香皂或洗手液等清潔用品；洗手時長不少於20秒等。
全球洗手日，你會不會正確洗手？正確洗手的7個步驟教你全面清潔手部遠離細菌：
1. Get your hands wet.
把手弄溼
Turn the tap on and evenly rinse your hands in warm water. Contrary to popular belief, hot water does not remove bacteria more effectively than warm water, and may even increase the "irritant capacity" of some soaps.
打開水龍頭，用溫水均勻的衝洗手部，人們普遍認為熱水比溫水除菌的效果更好，但事實並非如此。而且熱水還可能會增加某些肥皂的刺激性能力。
2. Use soap.
使用肥皂
Any type of soap will work, but if it helps you wash your hands more consistently to have soap that is a fun shape or color, or a pleasant fragrance, go for it.
什麼肥皂都管用。但如果你對某種可愛造型、顏色或是芳香的肥皂有特殊情結，它會讓你的洗手工作更能堅持下去，那就果斷用起來吧。
3. Work up a lather.
打肥皂泡
Scrub on both sides of your hands, in between your fingers, and your wrists. Remember to wash around and under your fingernails.
擦洗手部兩側，手指之間和手腕都記得擦洗乾淨。記得全面清洗，指甲下面也別放過。
4. Wash your hands for about 15-20 seconds.
洗15-20秒
Be sure and rub your hands vigorously, and don't rinse off the soap right away. Give it time to do its job and give yourself time to get soap everywhere it should be.
一定要用力的摩擦雙手，不要立即就把肥皂泡沫洗掉，你要花時間把肥皂泡沫均勻地擦滿整個手部，這樣才會發生作用。
5. Rinse your hands thoroughly.
徹底清洗手部
Place them under running water with your hands pointed downward but not touching the sink. This removes both the soap and the bacteria that was on your hands.
用流動的自來水衝洗手部，把手直接伸到水龍頭下面，但注意不要碰到水槽。這樣清洗才能去除掉手上的肥皂和細菌。
6. Use a towel to turn off the faucet, particularly in a public bathroom.
使用毛巾關掉水龍頭，特別是在公用衛生間
If the faucet turns itself off on a spring or a photocell, let it. If not, use a paper towel, your elbow, or your forearm.
如果水龍頭是通過彈簧或是光電管自行控制，那就不用管了。如果不是，請使用紙巾、肘部或是前臂來關掉水龍頭。
7. Dry your hands with a clean towel.
使用乾淨的毛巾擦乾手
Although they are not as good for the environment, paper towels are more sanitary for drying your hands than cloth towels. If you use cloth towels at home, launder them regularly. If you are in a public restroom, you can also use the hot air dryers if they are available.
雖然可能使用紙巾不環保，但是在擦乾手的時候使用紙巾要比毛巾衛生得多。如果你在家的時候使用毛巾，請記得定期洗滌。如果是在公共衛生間，要是有熱風烘乾機的話你也可以使用。
