M: Hello, Marry, I haven’t seen you in a while. What seems to be the problem?
W: Actually, I’ m a little embarrassed about coming here. I feel fine right now. But you know how much stuff is going around. Anyway, every year around the holidays, like clockwork, I come down with something.
M: So you are interested in preventions. What symptoms do you usually get?
W: You know, cough, fever, running nose, my head and bones ache, chills even. I’ m usually miserable for a week and it ends up ruining my holidays.
M: Sounds like a typical flu to me. As you said, lots of people have it. Influenza often strikes people who are overtired, stressed-out and not eating nutritious foods. And also you increase your exposure to a virus when you’ re in big crowds where lots of people are coughing and sneezing.
W: I certainly spend a lot of time in the department stores around the holidays, buying gifts for people.
M: Yes, and so you increase your exposure to air-borne viruses, just when your body resistance is already low from all of the running around you do.
W: So what can I do to ward off the flu?
M: Actually it’ s fairly simple. Get a lot of rest, eat well. That way your immune system will be bolstered, and you’ 11 be more able to fight off illness.
W: All these things make sense, but one more question. Aren’ t I bound to be sick, anyway, if there is an outbreak in the dorm?
M: You didn’t mention you live in the dormitory. In that case, I’ d also suggest you get immunized. The vaccine available prevents the three main types of influenza. Why don’ t you go to the university health center, the shots are free there.
W: I’ 11 do it right away. It would be nice to feel well during the holidays for once.
