Two types of bacteria live on our hands:resident bacteria, which are rarely implicated in infection and are good for the skin, and transient bacteria, which we pick up on our fingertips when we touch surfaces. The latter are the ones we want to remove.
我们手上有两种细菌:一种是常驻细菌，它很少与感染有关，而且对皮肤有好处;另一种是瞬时细菌，当我们触摸物体表面时，我们的指尖会接触到它们。后者是我们想要移除的。
You should wash your hands after going to the toilet, or changing a sanitary towel or tampon; after changing a nappy;before preparing food, after handling raw meat; and before eating. It is easy to pickup bacteria and viruses when travelling on public transport, so wash your hands afterwards.
如厕后、换卫生巾或卫生棉条后、换尿布后、准备食物前、处理生肉后及进食前，均应洗手。乘坐公共交通工具时很容易携带细菌和病毒，所以事后要洗手。
You need soap and, ideally, running water, but a bowl of water will do. Wet hands thoroughly and apply liquid or bar soap – if you apply soap to dry hands, it can act as an irritant and you don’t get coverage all over your hands. Rub your palms together, then interlink your fingers and rub them together. Next,place the fingertips of one hand in the palm of the other and rub, and viceversa. Rubbing the hands together creates friction, which removes the bacteria and creates a lather. Within that lather is the bacteria you have removed,ready to be washed away. Once you have worked up a good lather and rubbed all the surfaces together, rinse your hands and dry thoroughly, not forgetting in between the fingers. If you are out and using a paper towel, don’t lift the lid of the waste bin with your clean fingers. At home, change hand towels twice a week, or more often if someone has an infection such as norovirus.
你需要肥皂，最好是自来水，但一碗水就够了。彻底湿润双手，涂上液体或香皂——如果你把香皂涂在干燥的双手上，它会起到刺激的作用，你的双手不会被覆盖。把你的手掌揉搓在一起，然后把手指交叉在一起揉搓。接下来，将一只手的指尖放在另一只手的手掌上摩擦，反之亦然。双手一起搓会产生摩擦，从而去除细菌，产生泡沫。在泡沫里面是你已经清除的细菌，准备被冲走。一旦你产生了良好的泡沫，摩擦所有表面，冲洗你的手，彻底干燥，不要忘记在手指之间。如果你外出使用纸巾，不要用干净的手指打开垃圾桶的盖子。在家里，每周更换两次手巾，如果有人感染了诺如病毒，更换次数会更多。
