The common cold is the world's most widespread illness, which is plagues（疫病） that flesh receives. The most widespread fallacy（谬误） of all is that colds caused by cold. They are not. They are caused by viruses（病毒） passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes. During the First World War soldiers who spent long periods in the trenches（战壕）, cold and wet, showed no increased tendency to catch colds. In the Second World War prisoners at the notorious Auschwitz concentration camp（奥斯维辛集中营）, naked and starving, were astonished to find that they seldom had colds. At the Common Cold Research Unit in England, volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose. If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter？Despite the most pains-taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on. No one has yet found a cure for the cold. There are drugs and pain suppressors（止痛片） such as aspirin, but all they do is relieve the symptoms（症状）。

不能算是专业文章，科普文章而已，说的是感冒，希望大家看一看，
自己补充下，感冒病毒引起的感冒是自限性疾病，一般病程在2周左右，感冒治不好，药物起的作用是缓解症状，所以感冒症状不严重的话是不用吃药或者上医院的。预防主要靠锻炼身体和保持所在环境空气流通。

感冒是世界上分布最广的疾病，主要感染对象是人的身体。人们对其最广泛的误解集中于感冒是由于着凉所引起的。但其实不是，感冒是由于人与人之间传播的病毒所引起。人之所以感冒是由于相互之间直接或者间接的接触。在与世隔绝的北极地区，研究者称他们是不存在感冒的，直到通过空运的包裹或者邮件，与外界的感冒患者接触后，才会出现感冒。二战时，在臭名昭著的奥斯维辛集中营中，人们虽然忍冻挨饿，却令人惊讶地很少出现感冒。在英格兰的感冒研究联盟中，志愿者在一项试验中把自己弄得又湿又冷并保持一段时间。接着洗过一个热水澡后，穿上泳衣使他们身上留有冷水，然后站在一个湿淋淋的通风良好的房间内。一些人穿着湿的短袜，一些人则在雨中锻炼直到筋疲力尽。结果是，没有一名志愿者患上感冒，除非通过呼吸道传染上感冒病毒。如果又冷又湿的环境对感冒没有影响，那为什么感冒会在冬天多见呢？尽管进行了许多辛苦的研究，仍然没有人能找到答案。科学家的一种解释是，人们在天气冷的时候较平常更喜欢聚在一起待在家里，这使得感冒病毒更容易在人们之间传播。现在还没有找到感冒的治疗方法。有一些药物和止痛片比如阿司匹林，但也仅仅只是缓解症状而已。
