APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -You get a fever because your body is trying to kill the virus or bacteria that caused the infection. Most of those bacteria and viruses do well when your body is at your normal temperature. But if you have a fever, it is harder for them to survive. Fever also activates your body’s immune system.

Detailed explanation-2: -A higher body temperature accelerates the internal workings of cells. This means disease-fighting cells respond faster, and immune responses increase. Germs, on the other hand, don’t reproduce as well at higher temperatures. A very high fever can slow down or kill off the microbes that cause some infectious diseases.
