Fever is one of the body's natural defense mechanisms against infection. While uncomfortable, most fevers are not dangerous and resolve on their own. However, very high or prolonged fevers may require medical attention.
Conditions That Cause Fever

Tuberculosis
Common causeTuberculosis (TB) is a potentially serious bacterial infection caused by Mycobacterium tuberculosis that mainly affects the lungs but can affect other parts of the body.
Gout
