Globally, malaria is the major public health disease caused by plasmodium species and transmitted by the bite of the female anopheles mosquito. Assessment of the trend of malaria prevalence is important in the control and prevention of the disease. Therefore, the objective of this study was to assess the six year trend of malaria prevalence at the University of Gondar Comprehensive Specialized Hospital, northwest Ethiopia, from 2014 to 2019. A retrospective laboratory registration logbook review study was conducted on the malaria blood film examination results at the University of Gondar Comprehensive Specialized Hospital. The data was collected by using a data extraction tool and entered into SPSS version 20 for analysis. Descriptive statistics were used to summarize the socio-demographic characteristics of study participants and presented by graphs, tables and texts. The binary logistic regression was also used to test the association the trend of malaria prevalence and different factors like sex, age, year, and season. From a total of 17,500 malaria blood film examinations, 1341 (7.7%) were confirmed for malaria parasites. Of the confirmed malaria cases, 47.2%, 45.6% and 7.2% were P. vivax, P. falciparum and mixed infection, respectively. The proportion of P. vivax was the predominant species in the first three study years (2014–2016) and P. falciparum became the predominant species in the last three study years (2017–2019). The odds of malaria prevalence was lower by 68%, 60% and 69% in the year 2017, 2018 and 2019 compared to 2014, respectively. It was also 1.41 times higher in males than in females. Moreover, the odds of malaria prevalence were 1.60, 1.64, 2.45 and 1.82 times higher in the age group of < 5, 5–14, 15–24 and 25–54 years old compared to the older age groups (> 54 years old), respectively. Even there was a significant declining in prevalence trend; malaria is still a major public health problem. The study showed that there was high seasonal fluctuation from year to year. Moreover, males and the younger age groups were more affected than females and old age groups, respectively. Therefore, malaria prevention and control activities should be strengthened and require extra efforts by considering these variability.

Background: Malaria is disease caused by plasmodium species and transmitted by the bite of female anopheles mosquito. Globally, it is still the major public health problem that causes morbidity and mortality especially in tropical and sub-tropical African countries including Ethiopia. The objective of this study was to assess the Six year trend of malaria at University of Gondar Specialized Referral Hospital, northwest Ethiopia, from 2014-2019Method: A retrospective study was conducted by reviewing the laboratory registration logbook at University of Gondar Specialized Referral Hospital by using data extraction tool. The data was analysized by SPSS version 20. Descriptive statistics was used to summarize the socio-demographic characteristics of study participants and presented by graphs, tables and texts. The binary logistic regression was also used test the association of trend of malaria and different factors like sex, age, year, and season. Result: From a total 17,500 malaria suspected patients, 1341 (7.7%) were confirmed for malaria and (47.2%), (45.6%) and (7.2%) were P.vivax, P. falciparum and mixed infection, respectively. P.vivax was the predominant species in the first three years and P. falciparum became the predominant species in the last three years. The trend prevalence was showed a fluctuated significantly decrement. It decreased by 68%, 60% and 69% in the year of 2017, 2018 and 2019 compare to 2014, respectively. The positivity rate were significantly higher in the males (1.41 times higher) than females. It was also significantly higher in lower age groups compare to the older age groups (> 54 years old). It was 1.60, 1.64, 2.45 and 1.82 times higher in the age group of < 5, 5-14, 15-24 and 25-54 years old, respectively.Conclusion: There has been a significant declining trend of malaria in the study area. However, it is still a major health problem and requires extra efforts for further reduction. Even, autumn was the season when the highest peak of malaria cases in was observed, there was high fluctuation from year to year. Therefore, control activities should be continued and strengthened manner in the study area considering these variability.
