It's very important to understand that a fever is a normal response of the body to foreign invaders like bacteria and viruses. The body recognizes a foreign invader and the brain acts to increase body temperature to make things unsuitable for the foreign invader. Most bacteria can only tolerate a certain temperature range and once outside of it, do not survive.
Fever can support the immune system's attempt to gain advantage over infectious agents, such as viruses and bacteria, and it makes the body less favorable as a host for replicating viruses and bacteria, which are temperature sensitive. Infectious agents are not the only causes of fever, however.
