title: History of Tick Bite: A Gift or a Red Herring?
abstract: Fever of unknown origin can be challenging to the emergency medicine physician and the array of both benign and potentially life-threatening diagnoses on the differential can lead to a costly, time-consuming work-up. In this article, we present a case of potentially fatal tick-borne illness with a focus on history, physical exam, and laboratory findings that would differentiate this diagnosis from other causes of fever of unknown origin and aid in early and efficient initiation of treatment for patients.
