Y: Not the fact, Don. Sure, hand sanitizers kill the germs on your handsincluding the residentbacteria that live there, and the transient illness-causing bacteria you pick up off doorknobs. But unless you rinse them off in water, the dirt on your hands isnt affected. Its like sanitizing dishes without first rinsing them off.
事实并不是这样的,Don。诚然,洗手液能杀死手上的细菌,包括长期寄生菌,以及在门把手等东西上沾上的临时致病细菌。但是你若不将那些细菌洗入水中,你手上的细菌对你根本就毫无影响。这就像是你给碟子消毒却又不先将碟子冲洗干净一样。
D: Surely you jest.
开玩笑吧你!
Y: Whats more, as the alcohol evaporates, it strips your hands of their protective oils and pulls up resident bacteria that live in the deeper layers of your skin, so you may end up with more germs on the surface of your hands than you started with.
还有呢,在酒精挥发的时候会顺便将你手上的一层保护油和皮肤深层的寄生菌也带走,如此一来你手的皮肤表层的细菌可能比用洗手液之前还要多。
D: Oh, no. So whats the neading man to do?
那要怎么办啊,总要洗手啊!
Y: Rinserinse and rinse more. While hand sanitizers offer a quick fix, they work best inconjunction with soap and water.
