D
Fever, or pyrexia, is an important defense mechanism. Therefore most health care providers will not treat an adult's fever until it is higher than 39° C (102.2° F). Mild temperature elevations enhance the body's immune system by stimulating white blood cell production. Increased temperature reduces the concentration of iron in the blood plasma, causing the growth of bacteria to slow. Fever also fights viral infections by stimulating interferon, the body's natural virus-fighting substance.
