Borrelia hermsii is a spirochete bacterium representing the endemic causative agent of tick-borne relapsing fever in eastern regions of North America (more specifically, the eastern United States, and British Columbia region of Canada). It is spread by the soft-bodied tick Ornithodoros hermsi. Human infections characteristically occur among campers and people temporarily lodging in wooden accommodations in proximity to rodents. Human disease is usually relatively mild with low fever.[1]

Epidemiology

B. hermsii is endemic to regions of the U.S. with high elevation (whereas B. turicatae is endemic to low-lying regions such as Texas and Florida).[2]
