Fever is caused by an increase in heat production or a decrease in heat loss by the body due to various reasons. The clinical course of fever includes a first phase of rising body temperature, a second phase of hyperthermia, and a third phase of decreasing body temperature. Chills usually precede the fever, i.e., the period of rising body temperature, and disappear during the period of hyperthermia. Fever with chills is commonly seen in various infectious diseases, such as infectious diseases of the respiratory system, malaria, acute pyelonephritis, sepsis, and acute purulent cholangitis.
