A fever is usually caused by infections from viruses (such as a cold or the flu) or bacteria (such as strep throat or some ear infections). The fever itself is not the disease, only a sign that the body’s defenses are trying to fight an infection.
Fevers are generally harmless. In fact, they can be considered a good sign that your child’s immune system is working and the body is trying to heal itself. While it is important to look for the cause of a fever, the main purpose for treating it is to help your child feel better if he is uncomfortable or has pain.
