Abstract
Introduction: Malaria is the highly prevalent tropical disease with high morbidity and mortality as well as high economic and social impact. According to World Health Organization report in 2016, an estimated 216 million cases of malaria occurred worldwide in which 90% was from African Region. In Ethiopia about 75% of landmass of the country is malaria-endemic and 65% (58.5million) of the population is estimated to be at risk of malaria infection. South omo one of the malarias land marks of Ethiopia because of the existence of different risky factors in the area. The purpose of this study was to investigate the malaria outbreak in siremerate cluster Dasenech District in 2018.
Methods: We used microscopic and Rapid Diagnostic Test investigation to confirm the disease. We reviewed the previous year‘s malaria data to establish a threshold level and to understand the trends of the disease. The magnitude of the disease was described by person, place and time. We conducted an unmatched case-control study with 109 randomly selected cases and 109 community controls.
Result: Among the total of 638 suspected cases, 530 (83%) confirmed malaria cases. The Total Attack Rate was 9.6 per 1000popn and no malaria related deaths were reported during May 2018. Slide positivity rate was 83%. Of the total suspected cases 54.7% were female and specific AR were 9.7%. Person ages 5 - 14 years were most affected with an attack rate of 11.8%. Having Number of treated bed net per house hold one or less were 6.6 times more likely to be exposed to malaria parasites than those who have more than one treated bed net per house hold. Staying outside during night time were 48.5 times more likely to be exposed to malaria parasite than those who not staying out side during night time.
Conclusion: Staying outside during night time, malaria infection in the family and number of bed net one and less per house hold has also contributing risk factors for occurrence of the outbreak.
