"Wash your hands often and completely, with soap and running water!" We often hear this, but do you follow it? We know it's good for our health to wash hands. There's even a day to make us do it and know more about its importance. It is Global Hand-washing Day and it's on October 15. During the outbreak of COVID-19, washing hands plays an even more important role in preventing the virus (病毒) from going around.
People think of Doctor Semmelweis from Hungary（匈牙利） as the first person to find out the good results of hand washing. He pointed out the importance of hand washing to doctors, because they often worked with people who are seriously ill. And he saved a lot of people's lives by telling doctors to wash hands with chlorine (氯) before each examination (检查).After that, the number of dead patients （病人） became much smaller.
You might think everyone would be excited, because Dr. Semmelweis solved the big problem . But in fact things were quite different. Although Dr. Semmelweis kept asking doctors to wash their hands with chlorine, not every doctor accepted (接受) his idea. Some even sent him to a mental hospital. His idea became really popular years after he died.
Now that washing hands is of great importance, we should do it as carefully as we can. What's more, it's important to wash our hands in right ways.
