Popis: Background: In Ethiopia, the malaria epidemic continues to cause significant morbidity, accounting for the majority of outpatient visits. In Ethiopia, malaria transmission follows an unusual pattern, with large-scale epidemics occurring every 5–8 years. In Ethiopia, malaria is the leading cause of morbidity and mortality. In Ziway –Dugda, malaria is a major public health problem. The objective of this study was to look into the outbreak and determine the risk factors in the Ziway Dugda Woreda. Method: A 1:1 case-to-control ratio was used in this unmatched case-control study. The calculated sample size for this study was 216 and a simple random sampling technique was used to select cases and controls. SPSS version 25 was used to manage and analyze data collected on a clinical basis, disease risk factors, and knowledge assessments on the mode of transmission and prevention methods. Result: Of the total malaria cases (n=182), almost 100% of the cases were confirmed by RDT/ microscopy. In the district, the average attack rate was 28.9 per 1000 people. The most severely affected groups were those aged 5–14 years and females, with attack rates of 32.6 and 30.7 per 1000 inhabitants, respectively. The presence of an artificial water reservoir near the house [AOR =2.63, 95% CI 1.26, 5.49], staying outside at night [AOR =4.82, 95 % CI 2.33, 9.96], no knowledge of malaria transmission, prevention, and control [AOR =3.71, 95 % CI 1.78, 7.73], dense grass [AOR=3.86, 95% CI 1.40, 10.63], and the lack of a controlled environment [AOR =4.96, 95% CI 2.36, 10.41]. Conclusion: The malaria outbreak in Ziway Dugda mostly affected children aged 5 to 14. In multivariable logistic regression, lack of awareness about malaria transmission and control, the presence of stagnant water, staying outside at night, the presence of stagnant water, and poor environmental control were all significantly linked to the occurrence of the malaria outbreak. The community should be aware of malaria prevention and control measures.
