If I remember my immunology class right, it goes like this: When your immune system is 
presented with a challenge, it produces some chemicals called pyrogens (pyr=fire) which cause 
your body temperature to rise. Some bacteria contain pyrogenic substances that they excrete or 
are released when they die. The reason your body likes to run a fever is to make it a more 
hostile place for bacteria (they like 37dC not 39-40dC), your metabolism is speeded up to fight 
infection faster, and it makes some other defenses more active. It has been some time since I 
had all this, so it may not be quite right!
