- The fever is the immune system’s attempt to kill the infection. Very rarely, however, this immune response can result in a fever high enough to cause permanent harm or even life-threatening complications due to overheating. The causes of high fever vary, and they include such relatively routine conditions as sore throat, sinusitis, and urinary tract and other infections. Some causes may be more serious and include such conditions as appendicitis and pneumonia. In rare cases, high fevers can occur without any infection as a result of arthritis, lupus, or certain gastrointestinal and vascular disorders.
