Tick-borne relapsing fever

Description

A disease caused by an infection with the bacteria Borrelia. This disease is characterised by repeated episodes of fever, with the febrile episode lasting for approximately 3 days, followed by the afebrile state of approximately 7 days. Transmission is through the bite of an infected soft tick (from the genus Ornithodoros). Confirmation is by identification of spirochete bacteria from a blood smear, bone marrow, or cerebrospinal fluid.
