M: Please take a seat. What seems to be the problem?
W: I am feeling terrible. I have got a fever and felt pain in all my joints and muscles for a week. What’s worse, I began to feel short of breath this morning, especially when I did heavy work.
M: Do you have other symptoms?
W: I coughed a little and felt feverish. I have taken some aspirin, but it didn’t help.
M: Have you ever been to see a doctor?
W: No. I haven’t. I thought it was just a common cold and it would be better soon.
M: Have you had any chronic ailments of respiratory system?
W: No, I haven’t. I have always been fit before that.
M: Have you ever been to the crowded places, or contacted with others who had the same symptoms as yours?
W: Let me see. Oh. . . I remember that one of my friends was hospitalized a week ago, and others told me that he had been suffering from SARS. I thought it was just a joke at that time. Oh, no. . . I had a dinner with him two weeks ago.
M: I’m afraid you have to be hospitalized and be isolated now. We will give you a series of examinations to identify diagnosis.
W: Is it serious, doctor?
M: It is difficult to say just now exactly what’s wrong. Try to relax and keep calm. Now I would like to transfer you to the Isolated Ward. Pleas wait until we get the result of the blood test and the X-ray. If you are suffering from SARS indeed, in most condition you will be all right after proper treatment, although the process may be slow.
W: God bless me!
