The board-certified, fellowship-trained pediatric infectious disease specialists with Norton Children’s Infectious Diseases, affiliated with the UofL School of Medicine, have the training and experience to evaluate and treat unexplained fever, also called fever of unknown origin.

The pediatric infectious disease specialists with Norton Children’s Infectious Diseases will work to create a treatment plan based on the child’s age, current condition and medical history. Depending on the type of fever, current symptoms and other factors, our specialists may order tests to check for infections as well as other conditions that may be causing fever. Fever of unknown origin often is caused by unusual symptoms of a common disease rather than by an uncommon disease.
Unexplained fever is not treated with antibiotics or anti-inflammatory medicines unless there is evidence that a child may have tuberculosis or juvenile idiopathic arthritis.
