Background and objective: Malaria is a life-threatening disease remaining public health problem in Ethiopia in general and Metekel zone in particular. To design and implement evidence-based effective malaria control strategies, understanding its transmission dynamics through trend analysis of health facilities’ data is important. The objective of this study was to investigate the trends of malaria distribution in selected districts of Blue Nile valley in Metekel zone.
Methodology: Six years retrospective study was conducted at in lowest Blue Nile valley, Metekel zone. History of all patients visited the aforementioned institutions from 2014 to 2019 were reviewed. Malaria parasites confirmed slides on the laboratory registration books were carefully revised to assess the trends of malaria infections. Data were entered into excel computer program and analyzed using SPSS version 16.0.
Result: Out of a total of 542,419 patients diagnosed in the three districts’ health facilities, within six years, 369,065 (68.04%) were confirmed malaria parasite positive cases. The highest malaria positivity rate (n=156, 860, 82.39%) was reported from Dangure health institution which is greater than the sum result of both Pawe and Mandura. Plasmodium falciparum and P. vivax accounted for 63.75% and 33.60% respectively, while 2.64% were found to be mixed infection of both species. Males were more affected 213,014 (57.71%) than female 156051 (42.28%).
Conclusion: The current study concluded that malaria remain a public health problem, in which the deadly malaria parasite, P. falciparum is the predominant species in the area.
