It is a cold and dry winter morning. When you wake up, you feel that your throat hurts. You begin to feel cold and later you may cough. You must have a cold! Wait a moment. Could it just be a cold or the flu?
A cold gives you headache and cough. But it’s usually easy to get well. Take medicine or drink some hot tea. Usually you will feel better after a week.
On the other hand, the flu can be much more dangerous. It usually gives you fever. Sometimes it can cause people to die(死亡). According to an American report, the worst flu killed about 50 million people from 1918 to 1919.
But if you get a flu vaccine (疫苗), it can stop you from getting the virus (病毒). Flu vaccines give your body antibodies (抗体). So next time you get the flu, the antibodies should help you.
The flu virus changes every few years. There are so many kinds of flu, such as H1N1 and H5N1. The antibodies for one kind of flu can’t help us against all kinds of flu. That’s why we need to get the vaccine every year.
However, good health habits may also help stop you getting a cold or flu. Washing your hands often helps stop you from getting viruses. It is also important to get regular exercise and eat healthy food. All these can help to keep you healthy.
