Sep 4, 2023 · Fever, or pyrexia, is the elevation of an individual's core body temperature above a 'set-point' regulated by the body's thermoregulatory center in the hypothalamus. This increase in the body's 'set-point' temperature is often due to a physiological process brought about by infectious causes or non-infectious causes such as inflammation, malignancy, or autoimmune processes. These processes ...

Key Points. Fever is an elevated body temperature that occurs when the body's thermostat (located in the hypothalamus) resets at a higher temperature, primarily in response to an infection. Elevated body temperature that is not caused by a resetting of the temperature set point is called hyperthermia. Normal body temperature varies by.
Exogenous pyrogens (e.g. bacteria, viruses, toxins) initiate fever, usually within 2 h of exposure, by interacting with macrophages or monocytes, leading to cytokine induction. Other mechanisms to initiate fever include: Some endotoxins, produced by bacteria, act directly on the hypothalamus to alter the set point.
