When needed, in order to suppress bacterial growth, iron and zinc concentration in the blood reduces, which is nothing but a result of fever.
Fever is, perhaps, the most common of all health conditions diagnosed.

It is also the first sign that the body sends out to signal an infection or a disease that's coming on. It is the body's thermoregulatory set-point that rises to deal with a faulty mechanism occurring in the body. A fever is generally characterized by bouts of cold, and an increase in shivering, heart rate and muscle tone.

A low-grade fever is a mild increase in a person's normal body temperature. It ranges from 100.4° F to 102.2° F, and can be persistent in nature. It is important to note that mild elevation in body temperature can also be caused due to environmental factors, as well as rigorous physical activity.
