The fever of unknown origin, or the FUO can be defined as the condition when the body temperature of a person is at 101 degree Fahrenheit for at least a period of the three weeks without any observable underlying cause. The most common causes of the FUO includes, infections (such as Lyme disease, tuberculosis), malignancy (such as leukemia), inflammation (such as inflammatory bowel disease), and alcohol or drug abuse.
