　　Sour throats, runny noses and body aches all mean misery, but being able to tell if the cause is a cold or the flu may make a difference in how long the misery lasts, because the drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter (OTC非处方药) remedy, the sooner relief will come.

　　The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses — flu A,B and C. There is no cure for either illness, but the flu can be prevented by the flu vaccine (疫苗)，which is, for most people, the best way to fight the flu. But if the flu does strike, quick action can help. Although the flu and common cold have many similarities, there are some obvious signs to look for. Cold symptoms such as stuffy nose, runny nose and sour throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, painful throat and body aches come on suddenly and are more worrying than cold symptoms. It may be particularly difficult to tell when babies and preschool-aged children have the flu. It advises parents to call the doctor if their small children have flu-like symptoms. Both cold and flu symptoms can be eased with the OTC medication as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of a rare but serious condition affecting the liver and central nervous system. There is, of course, no vaccine for the common cold. But frequent hand washing, and avoiding close contact with people who are having colds can reduce the probability of catching one.
