One worker (9%, 95% CI: 2每38) seroconverted against orientiae during the study period. This is the first evidence of orientiae exposure in the Horn of Africa. SFGR were also identified by polymerase chain reaction in 32 of 189 (11%, 95% CI: 8每15) tick pools from 26 of 72 (36%) cattle. Twenty-five (8%, 95% CI: 6每12) tick pools were positive for Rickettsia africae, the causative agent of African tick-bite fever. Health-care providers in Djibouti should be aware of the possibility of rickettsiae infections among patients, although further research is needed to determine the impact of these infections in the country %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4973201/
