African Tick Bite Fever in Travelers to Rural Sub-Equatorial Africa [PDF]

Clinical Infectious Diseases, 2003
To estimate the incidence of, identify risk factors for, and describe the clinical presentation of travel-associated African tick bite fever (ATBF), a rapidly emerging disease in travel medicine, we prospectively studied a cohort of 940 travelers to rural sub-Equatorial Africa.
