Unexplained fever can have various causes, ranging in severity from 'minor' to 'generally fatal'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose unexplained fever, we could:
|Crohn's Disease||2%||Ruled out|
|Lupus (SLE)||0%||Ruled out|
|Ulcerative Colitis||0%||Ruled out|
|Epstein-Barr Virus||0%||Ruled out|
|Rheumatoid Arthritis||0%||Ruled out|

Fevers can occur due to associated bacterial, viral, or fungal infections.
A less common but more serious constitutional feature of SLE is persistent fever.
