来源：One/Change

Is there a difference between using Purell vs. antibacterial soap vs. plain soap and water in cleaning the hands and preventing illness?
用净手液、抗菌皂或者是普通肥皂和水来洗手时，它们三者的效力究竟有什么不同呢？

The overall answer- Hand washing with plain soap and water is best!
一句话：用普通肥皂和水来洗手最干净！

The recent marketing of antibacterial everything has changed consumer thought that antibacterial soap is necessary to get rid of all the bacteria on your hands. Well it is not. It is a marketing gimmick.
近期各种抗菌类消费品的销售活动使得消费者产生了这么一种想法：抗菌肥皂对于杀灭手部细菌是不可或缺的。但这不是真的，这只不过是商家的诡计而已。

There is actually concern regarding the use of so many antibacterial agents because there are superbugs. Superbugs are bacteria that are resistant to antibiotics. Superbugs have become resistant to antibiotics because of the overuse of antibiotics. So when people get sick and really need antibiotics a stronger antibiotic has be used but there are a limited number of antibiotics available.
我们必须注意到使用如此之多抗菌药剂的后果---超级病菌。超级病菌是一种具有耐药性的病菌，由于人们滥用抗菌素而使得它具有了这种耐药性。所以，当人们得病真正需要抗菌素治疗的时候，结果只有相当少的抗菌素能够真起到作用。

Purell is convenient and portable but is no replacement for hand washing with soap and water. Purell works by killing all organisms on the skin, even natural microorganisms. This is bad, because those microorganisms are needed to keep the skin healthy and kill the bad organisms. Purell is helping the environment on hands grow more bad organisms. If you can wash your hands with soap and water it is better than using Purell.
净手液使用起来的确很方便，但是它不能取代肥皂和水。净手液的工作机理是杀灭皮肤表面的所有有机生物，甚至包括天然微生物。这一点非常糟糕，因为我们的身体需要这些微生物去保持皮肤的健康和抑制有害的有机生物。但是净手液却在为这些有害有机生物创造生存环境，所以用水和肥皂洗手要比使用净手液好。

Several randomized control studies have been done looking at the effectiveness of antibacterial soap vs. plain soap in reducing childhood illness (mainly diarrhea). The results– Plain hand soap worked just as well as antibacterial soap. Antibacterial is not more effective than washing your hands with plain soap and water.
在一些随机进行的控制实验中，就抗菌皂和普通肥皂对减少儿童疾病（主要是腹泻）的效能做出了测试。结果显示，普通肥皂和抗菌皂的效果一样好，抗菌皂并没有显示出特别的功效。

1. Wash you hands with plain soap and water.
1、用普通肥皂和水来洗手
2. Don’t use antibiotics when it is not necessary. (Antibiotics do not work for viruses)
除非必须如此，否则不要用抗菌类产品洗手（抗菌素对病毒无效）

注：Purell，普瑞来，免水即时净手液。
