📋Overview
Deerfly fever is a legacy term historically used to describe a febrile illness caused by infection with bacteria of the genus Francisella, primarily Francisella tularensis, the agent of tularemia. The modern preferred term for this condition is tularemia. Tularemia is a zoonotic infection transmitted to humans through bites of infected arthropods such as deerflies, ticks, or via contact with infected animals. The term 'deerfly fever' emphasizes the vector-borne nature of some tularemia cases but is not commonly used in current medical practice.
