Fever is a common symptom of many different types of illnesses, infections, and diseases. It occurs when the body's immune system fights off an infection or some other type of foreign invader, such as a virus or bacteria.

When the body is fighting off an infection, it releases chemicals called cytokines that can cause inflammation and increase the body's temperature. This increased temperature helps to kill off the invading microorganisms, which is why fever is often considered a helpful response to illness.
