What is the mechanism of fever development?

The mechanism of fever appears to be a defensive reaction by the body against infectious disease. When bacteria or viruses invade the body and cause tissue injury, one of the immune system’s responses is to produce pyrogens.

What is pathogenesis of fever?

Fever, or pyrexia, is an elevation in body temperature caused by a cytokine-induced upward displacement of the set point of the hypothalamic thermoregulatory center. The purpose of fever isn’t completely understood, but small elevations in body temperature appear to enhance immune function and inhibit pathogen growth.

What causes fever physiology?

Fever occurs when there is an elevation in the body’s thermoregulatory set-point either by endogenous or by exogenous pyrogen. In hyperthermia, the set-point is unaltered, and the body temperature becomes elevated in an uncontrolled fashion due to exogenous heat exposure or endogenous heat production.

What are the three classifications of fever?

Three major fever types have been described including sustained/continuous fever, intermittent fever and remittent fever [31], [38].

Why moderate form of fever is good for health?

Many components of the nonspecific and specific host response to infection are enhanced by small elevations in temperature. Perhaps more important, studies of bacterial- and viral-infected animals have shown that, in general, moderate fevers decrease morbidity and increase survival rate.

What are the five types of fever?

The 5 types of fever are intermittent, remittent, continuous or sustained, hectic, and relapsing. A fever is a physiological problem when your body temperature is above the normal range.

What are the types of viral fever?

Examples

• Ebola.
• Lassa fever.
• dengue fever.
• yellow fever.
• Marburg hemorrhagic fever.
• Crimean-Congo hemorrhagic fever.

How does fever protect the body?

A fever fights infection by helping immune cells to crawl along blood-vessel walls to attack invading microbes.
