Fever occurs when the body senses the presence in the blood of small molecules known as “pyrogens”. Pyrogens are produced by cells of the immune system in reaction to either bacteria, viruses, toxic substances, etc. Pyrogens disturb the central nervous system’s regulation of body temperature, resulting in an elevation of body temperature. The most common causes of fever in children are viral infection or bacterial infections. Sometimes a fever can be caused by something more severe, such as an ear, bladder or kidney infection.
Medications, Illicit drugs, Illnesses related to heat exposure may also cause fever.
