Pyrexia refers to what condition?

Explanation:
Pyrexia refers to fever, an elevation of the body's core temperature in response to infection or inflammation. This happens when pyrogens raise the hypothalamic set point, prompting the body to generate and conserve heat to reach a higher temperature. Fever helps the immune system fight pathogens. It’s different from hypothermia (low body temperature) and from a normal, afebrile state. Clinically, fever is typically defined as a temperature above the normal range (commonly about 38°C or 100.4°F), depending on measurement method.
