In brief: Increase metabolism
Fever is a created by the increase in metabolism used to fight infection.
The increase drives up the heart rate (more blood carrying immune factors &white cells around), increases respiratory rate (adding more oxygen to the effort). Germs whether virus or bacteria don't generally reproduce as fast when the body gets hot.This response probably developed over time as those capable of fever did better.

In brief: Countless
There are countless causes for fever in a child.
Teething in infants and common infections are highest on the list at this age bracket. Remember that fever is not a dangerous or bad thing for your child. Its simply a weapon your body uses to fight the problem. Fever is a normal reaction to illness. Most fevers are caused by benign issues, see your pcp in order to find the root cause of the fever.
