You can't beat it, but you don't have to join it. Maybe it got the name "common cold" because it's more common in winter. The fact is, though, being cold doesn't have anything to do with getting one. Colds are caused by the spread of rhinoviruses, and, at least so far, medical science is better at telling you how to avoid getting one than how to get rid of one.

Children are the most common way cold viruses are spread to adults, because they have more colds than adults--an average of about eight per year. Why do kids seem so much more easily to get colds than their parents？ Simple. They haven't had the opportunity to become immune to many cold viruses.

There are more than 150 different cold viruses, and you never have the same one twice. Being infected by one makes you immune to it--but only it.

Colds are usually spread by direct contact, not sneezing or coughing. From another person's hand to your hand and then to your nose or eyes is the most common route. The highest concentration of cold viruses anywhere is found under the thumbnails of a boy, although the viruses can survive for hours on skin or other smooth surfaces.

Hygiene is your best defense. Wash your hands frequently, preferably with a disinfectant soap, especially when children in your household have colds.

But even careful hygiene won't ward off. every cold. So, what works when a coughing, sneezing, runny nose strikes？

The old prescription of two aspirins, lots of water, and bed rest is a good place to start. But you'll also find some of the folk remedies...Hot mixtures of sugar (or honey), lemon, and water have real benefits.

ists can send a man to the moon, why can't they find a cure for the common cold？ The answer is easy. There're actually hundreds of kinds of cold viruses out there. You never know which one you will get, so there isn't a cure for each one. When a virus attacks your body, your body works hard to get rid of it. Blood rushes to your nose and causes a blockage in it. You feel terrible because you can't breathe well. But your body is actually eating the virus. Your temperature rises and you get a fever. But the heat of your body is killing the virus. You also have a running nose to stop the virus from getting to your cells. You may feel miserable but actually your wonderful body is doing everything it can to kill the cold. Different people have different remedies for colds. In the United States and some other countries, for example, people might eat chicken soup to feel better. Some people take hot baths and drink warm liquids. Other people take medicines to relieve various symptoms of colds. There's one interesting thing to note. Some scientists say taking medicines when you have a cold is actually bad for you. The virus stays in you longer because your body doesn't develop a way to fight it and kill it.

According to the passage, why haven't the scientists find a cure for the common cold？

A．There are too many kinds of cold viruses for them to identify.

B．There is no cure.

C．They are too busy.

D．The virus is too small.
