Symptoms and cures

How do you know when you have the flu? When we are ill, we have signs of the illness called symptoms. Different illnesses have different symptoms.
Look at the picture below to see some of the symptoms of flu. One of these symptoms is a fever. Medicines help to take away the symptoms of the illness.
Often we become ill because germs enter our body. Medicines can help to kill the germs and make the illness go away. When medicines make an illness go away, we say that the medicines cure us.

Medicines make us better but we have to take them safely. You should only take medicines if they are given to you by a doctor, a nurse or an adult who looks after you. Sometimes a doctor will prescribe medicines.
