[Acute viral infections: the clinico-immunologic role of high fever].

In acute viral infections with high fever a reduction of body temperature by the action of antithermics effects a brief clinical improvement but shortly the temperature rises again to the levels higher than previously. This indicates an aggravation of the disease. The consequent hyperthermia can be controlled while synchronously the immunologically favorable effect of fever on the activation of the defense reaction of the diseased organism is preserved; this is achieved by a special procedure regulates high febrility.
