Fever - Causes


  • Fever is caused either outside or inside the body. Micro-organisms such as bacteria and parasites produce a substance called chemical poisons. This poison causes the white blood cells to produce a substance called pyrogens which in turn causes fever.
  • Fever occurs when your body's thermostat shifts the set point of your normal body temperature to higher. During this time you may feel cold and so start adding a layer of clothing or wrap up in a blanket, or you may be shivering to generate more body heat, which results in an increase in body temperature.
  • It is caused by the following:
    • Colds and flu
    • Bacterial infection
    • Infections of the ear, lung, skin, throat, bladder or kidney
    • Gastroenteritis stomach bugs
    • Heat exhaustion
    • Extreme sunburn
    • Virus
    • Side effects of drugs
    • Cancer
    • Malignant tumor
    • Infections from outside, such as malaria
    • Autoimmune diseases such as lupus, rheumatoid arthritis and inflammatory bowel disease
  • As a whole one could say fever is not contagious; however, if the fever is caused by a viral or bacterial infection, then it is a contagious infection.
