Borrelia recurrentis is a species of Borrelia, a spirochaete bacterium associated with relapsing fever.[1][2] B. recurrentis is usually transmitted from person to person by the human body louse.[3] Since the 1800s, the body louse has been known as its only known vector.[4]

B. recurrentis DNA was found in 23% of head lice from patients with louse-borne relapsing fever in Ethiopia. Whether head lice can transmit these bacteria from one person to another remains to be determined.[4]
It is notable for its ability to alter the proteins expressed on its surface, which causes the "relapsing" characteristic of relapsing fever.[5]
