Detailed explanation-1: -Innate immunity also comes in a protein chemical form, called innate humoral immunity. Examples include the body’s complement system and substances called interferon and interleukin-1 (which causes fever).

Detailed explanation-2: -What is the immune system? The immune system protects your child’s body from outside invaders. These include germs such as bacteria, viruses, and fungi, and toxins (chemicals made by microbes). The immune system is made up of different organs, cells, and proteins that work together.

Detailed explanation-3: -Fever, the regulated increase in the body temperature, is part of the evolved systemic reaction to infection known as the acute phase response.

Detailed explanation-4: -A fever is part of the inflammatory response that extends beyond the site of infection and affects the entire body, resulting in an overall increase in body temperature. Like other forms of inflammation, a fever enhances the nonspecific innate immune defenses by stimulating white blood cells to kill pathogens.

Detailed explanation-5: -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.
