     Do you have a sore (痛的) throat, a running nose and a headache? Do you keep coughing and

sneezing? If you do, the chances are that you have a cold or perhaps flu-but which one? Although both

colds and flu are caused by viruses (病毒), they are very different illnesses.

     Colds, which usually last about a week, affect the nose most. They commonly cause a runny nose and

sneezing. Sometimes, they cause a headache, a cough and slightly aching muscles.

     Flu is much more serious illness and is caused by different group of viruses. People with flu usually get

all the symptoms (症状) described above. However, they also get a high fever, a dry cough and much

worse aching. Fever is one of the typical (典型的) symptoms of the flu for all ages. The symptoms also

last much longer. Sometimes they don't disappear for at least two weeks.

     Flu can be a deadly disease. The elderly, who are weaker and less healthy than most younger people,

can die from flu. This is one reason why old people are advised to have a flu injection (预防针) before

the start of winter when flu is most common. This injection is inexpensive and definitely worth it.

     If you have a cold or flu, you must always deal with used tissues carefully. Don't leave dirty tissues on

your desk or on the floor. Someone else has to pick these up and viruses could be passed on. And finally, remember to cover your nose and mouth when you sneeze!You don't want to see the small drop of

liquids blown out of your nose and mouth when you sneeze, do you? Disgusting (讨厌的), eh? Now you

can undersdand why it's a good idea to cover your nose and mouth when you sneeze!
