“…However, these ndings are less than similar reports from 10 years data documented in Metema Hospital, northwest Ethiopia (91%) [24], and sub-Saharan African countries, where 99.7% of estimated malaria cases were due to P. falciparum [25], which could be related The study also revealed higher positivity rate of malaria among males (58.1%) than females (41.9%). This nding is in agreement with other studies conducted in various areas of Ethiopia, which reported higher malaria prevalence in males than females [15,18,22,27]. Such higher malaria prevalence in males is conceived to be attributed to the fact that males are usually engaged in outdoor activities that put them at greater risk of contracting the disease [22,28].…”

Background: In Ethiopia, malaria is a serious public health concern and has great impact on socio-economy. The trend analysis of malaria data from health facilities is useful for understanding its transmission dynamics and implementing evidence-based malaria control strategies. The aim of this study was to determine the trends of malaria infection in Guba district, western Ethiopia. Methods: A retrospective study was undertaken at Mankush Health Centre, western Ethiopia. All malaria cases reported from 2014 to 2018 were carefully reviewed from the laboratory record books to determine the trends of malaria morbidity. Data were analyzed using SPSS version 20.0. Results: In total, 16,964 malaria suspects were diagnosed using microscopy over the last 5 years, of which 8,658 (51.04%) were confirmed positive cases. Plasmodium falciparum , P. vivax , and mixed infection (both species) accounted for 75.2%, 24.5% and 0.28% of the cases, respectively. Males patients were more affected (n=5,028, 58.1%) than female ones (n=3,630, 41.9%). Of the total confirmed cases, 60.4% were age group of subjects (≥ 15 years) followed by 22.6% of 5-14 years and 15.9% of under 5 years. High malaria prevalence was observed in spring (September to November) season, while the least was observed in autumn (March to May) with the prevalence of 45.6% and 11.5%, respectively. Conclusions: The study demonstrated that malaria is a public health concern, in which P. falciparum is the predominant species followed by P . vivax . Therefore, the district health bureau and other concerned stakeholders should strength evidence-based malaria control and prevention interventions to interrupt disease transmission and eventual reduction malaria of malaria cases in Guba district.

“…Regarding age, the highest affected age group was > 15 years accounted for 54% followed by 5-14 age group 23.5% while the least affected age group was < 1 year in both sexes and the most frequently reported species in all age groups were P. vivax. The highest malaria prevalence in the adult age group obtained was in agreement with other findings reported across Ethiopia [19,22,27,28]. Whereas a finding from Arsi Negelle [29] showed that highly affected age group was 0-5 years followed by 16-20 years old.…”

“…In the present study, Plasmodium infection was nearly equal with only slight variation among males and females which was comparable with a study conducted in Wolaita zone [19]. This finding was in contrast with the majority of the study done in Ethiopia [25,26] where males were highly affected by malaria than females.…”

“…The maximum and minimum confirmed malaria case was reported in 2015 and 2018 respectively. However, the prevalence was lower than reported from other retrospective studies conducted in Adi Arkay health center (36.1%), Serbo health center (43.8%), Halaba special district (9.5%) and Wolaita zone (33.27%) [16][17][18][19]. This variation might be due to climatic and altitude differences.…”

Background: Malaria is one of the main public health challenges in Ethiopia that hinder the productivity and development of the country. In 2018, Ethiopia is on track to minimize the incidence of malaria by 40% as per its 2020 malaria reduction strategy. Currently, Ethiopia is working to eliminate malaria in 2030 by extending the 2020 strategy. Hence, this study aimed to analyze the trend of malaria prevalence in Wolkite health center, Gurage zone, Southern Central Ethiopia from 2015 to 2018. Methods: A retrospective study was conducted to determine the prevalence of malaria by reviewing the malaria registration laboratory logbook at Wolkite health center from 2015 to 2018. For all patients, blood films were done for the detection of malaria cases. All the socio-demographic data, year, month and malaria data were collected using a predesigned data collection sheet from January to March, 2019. Results: From a 121,230 clinically malaria suspected patients, the overall prevalence of microscopically confirmed cases were 8.56% (n = 10,379/121,230). Plasmodium vivax was the most predominant species accounted for 69.7% (n = 7237/10,379) followed by Plasmodium falciparum 29.3% (n = 3044/10,379). Age group > 15 years old were more affected by malaria accounting 54% (n = 5609/10,379) and malaria cases regarding sex were proportional (51.1% of males and 48.3% of female). Among the catchment areas, a higher number of malaria prevalence was recorded in the Wolkite town 66.2% (n = 0.6538/10,379). Higher malaria cases were shown in the season of Spring 29.8% (n = 3096/10,379) while lower cases 20.4% (n = 2123/10,379) were seen in the Winter season. Conclusion: The prevalence of malaria in Wolkite health center showed a consistent downward trend from the year of 2015-2018. Importantly, the higher prevalence of P. vivax seems overlooked in the study area. Therefore, malaria prevention and control strategy should be reinforced to reduce the prevalence of malaria in the study area.

“…This was in agreement with a study conducted in Kola Diba Health Centre [4]. However, in contrast to this finding, the study conducted in Wolita showed high malaria positivity in 5–14 year olds [17]. The reason why malaria affects the 15–45 age group in Kombolcha might be because these age groups are productive and as a result they are actively involved in industrial and agricultural activities.…”

BackgroundMalaria is one of the most serious public health problems in the world, and is a major public health problem in Ethiopia. Over the past years, the disease has been consistently reported as the first leading cause of outpatient visits, hospitalization and death in health facilities across the country. This study aimed to assess malaria prevalence trend in the Kombolcha Health Centre.MethodsA retrospective study was carried out in the Kombolcha Health Centre, north-central Ethiopia. Malaria cases reported from 2009 to 2016 were carefully reviewed from the laboratory record books. Interventions that had been taken in each year were collected from the district health bureau and head of Kombolcha Health Centre using checklists.ResultsA total of 27,492 blood films were examined from malaria-suspected patients in the Kombolcha Health Centre from 2009 to 2016. Malaria was confirmed and reported in 2066 (7.52%) of the examined blood films with 258 mean annual cases of. Minimum and maximum cases were reported in 2009 and 2010, respectively. Plasmodium falciparum and P. vivax accounted 60.2% and 35.5% of the cases, respectively. Male patients were more affected (n = 1407; 68.1%) than female ones (n = 659; 31.89%). The highest malaria prevalence (n = 1440; 69.69%) was seen in the 15–45 years age group, followed by those 5–14 years old (n = 303; 14.67%), and finally patients under five years old (n = 217; 10.5%). Malaria cases were at a peak in spring and reduced in the winter season.ConclusionAlthough the current malaria control strategies are effective in decreasing the morbidity and mortality, malaria is still among major public health problems in Ethiopia. Plasmodium falciparum is the dominant species in the study area. However, in recent years P. vivax cases are increasing, indicating that attention should also be given to this species. The efficacy of chloroquine for P. vivax should be evaluated in the study area. Control activities should be continued and scale up.
