Introduction: Ethiopia is the main endemic focus of louse borne relapsing fever. Borrelia recurrentis is the etiologic agent for louse-borne relapsing fever and occurs as epidemic under conditions of poor socio economic status, overcrowding, poverty, draught and famine. Methods: Unmatched community based case control and descriptive cross sectional investigation were conducted. All patients from 15 October-15 November 2012 were included. Sixty eight patients matched with 136 controls that had no previous history of relapsing fever living in the same village. Study was conducted in in households with individuals who go to work on a daily basis and data was analyzed using Microsoft Excel and Epi-Info version Among all confirmed patients 100% (68), 92.6% (63), 94.1% (64) and 82.3% (56) presented with fever, head ache, chills and vomiting respectively. There was no death during the outbreak. Mean age of respondents was 21 years and their median age was 20 years (SD 7.14). Statistically significant associations were observed between 51 (75%) patients and 27.2% (37) controls who did wash their clothes at least weekly (AOR = 13.23, 95% CI [5.51-31.75]) and 79.4% (54) patients and 64% (87) controls who did not take body bath at least weakly (AOR = 8.01, 95%CI [3.51-18.29]) and the associations were statistically significant. Those not washing clothes and taking baths at least weekly had a 13 and 8 fold likelihood of acquiring relapsing fever compared to those who wash clothes and take baths respectively at least on a weekly basis. Conclusion: Poor personal hygiene was contributed to the outbreak. The outbreak was contained due to prompt interventions taken and strong preventive measures were recommended to prevent emergence of future outbreak of relapsing fever.
