    Background: Malaria continues to be the most significant mosquito-borne disease globally but it holds a particularly heavy burden across many countries in Africa where in 2015. Malaria is the leading public health problem in Ethiopia where over 75% of the land surface is at risk with varying intensities depending on altitude and season .Gelana woreda is frequently attacked by malaria outbreak .We investigated the outbreak to identify risk factors undertake and recommend proper public health action . Method: We conducted descriptive and case control study in Gelana woreda. We interviewed PHEM staff’s on the prevention and control program, used outbreak investigation questionnaire to asses’ risk factor for both cases and controls. We collected 65 cases and 65 controls matched with age group, sex and residence .We analyzed the data with Epi Info. Version 7.2 and SPSS.V 23. Results are presented in analytic statistics and characterized in Time, Place and Person. Result: We identified that the outbreak was in three clusters and investigated in two clusters. Males are more affected than Females (37:28) and the younger Age group of the 0-4, 33(50%) followed by 5-9, 11(16.9 %) are more affected .The overall attack rate of the 32/1000. We compared the sociodemographic variable Sex and Age group the risk factors Indoor Residual Spray (IRS) home, staying out door in the evening and at night, living around intermittent river, stagnant water irrigation and type of home among cases and controls. We found significant association in bivariate analysis at 95% CI on Intermittent River, Stagnant water and irrigation. In multivariate analysis Intermittent river and stagnant water have significantly associated with the Gelana malaria outbreak (P=0.001)[ AOR (7.003)=,95% CI (2.23-22.03)]and (P=0.001)[ AOR (4.303)=,95% CI (1.7-10.358)], 3.2 (1.9-6.3) respectively. Conclusion: Malaria outbreak is confirmed in Gelana woreda .The risk factors for the outbreak was intermittent river and stagnant water. Prevention and control programs were not properly functioning.
