In the simplest terms, when good cells die they breakdown and leave a flare behind. The scout white blood cells immediately go there to investigate and try and quarantine off the area and once they're there they also release a big smoke signal which attracts the calvary. The scout cells CAN fight but they're undertrained and poorly equipped.
Once the calvary and scouts are fighting, they'll often send a messenger back home who contacts the specialist to come join the fight... the specialist are veteran cells who trained to fight in specific conditions and better equipped.
In order to ensure the enemies are defeated the body itself makes the entire battle field cater to their advantages. Fevers, selectins, permeability etc all are auto responses to improve the wbcs shots at winning and being effective

That's the best explanation of why symptoms, such as fever, happen that I've ever read.
It's to disadvantage the invader and provides an advantage to the defense.
Sometimes the defense can cause more harm than good, but that's a different topic.
