Relapsing fever, as its name implies, is an illness characterized primarily by recurrent episodes of fever, often accompanied by fatigue, malaise and other constitutional symptoms. It is caused by at least 15 spirochete species belonging to the genus Borrelia, and can be vectored to humans by either lice or ticks. Louse-borne relapsing fever (LBRF) is caused by Borrelia recurrentis and is transmitted from human to human by the body louse, Pediculus humanus humanus.
