Background: Ethiopia has been progressing very well in controlling malaria in the past few years. However, shortly after the COVID-19 pandemic, an unpredictable malaria resurgence was observed in almost all malaria-endemic areas of the country, although the exact cause of which has not yet been identified. Therefore, this study aimed to investigate malaria burden and associated risk factors in one of the endemic zones of Ethiopia.

Article Synopsis
  • Malaria is highly influenced by climate and seasonality, with factors like rainfall, temperature, and humidity playing crucial roles in its epidemiology, especially in tropical regions like Ethiopia.
  • In Ethiopia, there has been a significant increase in malaria cases, prompting a study in the Oromia zone to analyze the effects of seasonal and climate variability from 2014 to 2019, using patient and meteorological data.
  • The findings revealed a 12.7% malaria positivity rate, with high positivity linked to certain months and fluctuating rainfall, while the overall malaria cases showed a decrease of 20.5% over the study period.

Background: Plasmodium vivax is the second most common malaria parasite in Ethiopia. It has been treated with chloroquine (CQ) for the past seven decades. However, the emergence of CQ-resistant strains in the nation urged the Federal Ministry of Health of Ethiopia to review its national malaria treatment guideline in 2018.

Background: Soil-transmitted helminthic (STH) infections are the leading cause of stunting among children. To lessen the burden, the World Health Organization (WHO) recommended a periodic deworming program through the use of single-dose therapy in the endemic regions. Therefore, the purpose of this study was to synthesize evidence about the efficacy of anthelminthic drugs against STH infections among preschool and school-age children.

Background: The scaling-up of antiretroviral therapy (ART) is the greatest accomplishment to reduce the burden of acquired immunodeficiency syndromes (AIDS) to date. However, it requires optimal adherence to be effective. Thus, this study was designed to assess the level of adherence of people living with HIV (PLWH) to ART and its determinants in one of the hardest-hit areas with HIV in Ethiopia.

Background: Countries in malaria endemic regions are determinedly making an effort to achieve the global malaria elimination goals. In Ethiopia, too, all concerned bodies have given attention to this mission as one of their priority areas so that malaria would be eradicated from the country. Despite the success stories from some areas in the country, however, malaria is still a major public health concern in most parts of Ethiopia.

Background: Ethiopia is one of the few countries in Africa where Plasmodium vivax commonly co-exists with Plasmodium falciparum, and which accounts for ~ 40% of the total number of malaria infections in the country. Regardless of the growing evidence over many decades of decreasing sensitivity of this parasite to different anti-malarial drugs, there has been no comprehensive attempt made to systematically review and meta-analyse the efficacy of different anti-malarial drugs against P. vivax in the country.

Anemia is one of the major causes of morbidity for pregnant women in resource-limited regions. Yet robust research-based evidence on this vital public health problem in remote areas where the problem could be massive is quite limited in Ethiopia, one of the developing countries. Thus, this study is aimed to assess the magnitude of anemia and its associated risk factors among pregnant women attending one of the health facilities in Ethiopia.

Background: Soil-transmitted helminths (STH)/geohelminths are human parasitic nematodes which need soil contact for their egg development and become infectious. It is widely prevalent in developing countries. In Ethiopia, too, the same problem exists although the prevalence varies from place to place depending on the presence of risk factors and hygienic status of the community.

Background: Malaria causes a reduction in haemoglobin that is compounded by primaquine, particularly in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency. The aim of this study was to determine the relative contributions to red cell loss of malaria and primaquine in patients with uncomplicated Plasmodium vivax.

Methods: A systematic review identified P.

Objective: To assess the status of malaria prevalence in one of the malaria endemic areas of Ethiopia.

Results: A 10-year report of malaria cases were obtained from Asendabo Health Center, Jimma zone, Southwest Ethiopia. Following a retrospective study design, data of 68, 421 febrile patients diagnosed and treated in the health center were included in the study.

Background: Chloroquine remains the mainstay of treatment for Plasmodium vivax malaria despite increasing reports of treatment failure. We did a systematic review and meta-analysis to investigate the effect of chloroquine dose and the addition of primaquine on the risk of recurrent vivax malaria across different settings.

Methods: A systematic review done in MEDLINE, Web of Science, Embase, and Cochrane Database of Systematic Reviews identified P vivax clinical trials published between Jan 1, 2000, and March 22, 2017.

Objective: Objective of the study was to evaluate in vivo anti-plasmodial activities of Combretum molle seed extract.

Methods: As a standard protocol, initially the acute toxicity of the plant seed extract was checked following single administration of crude seed extract of the plant at doses 500, 1000 and 2000 mg/kg. This was followed by evaluation of anti-plasmodial activity of crude seed extract of the plant following a 4 days suppressive test.

This study was designed to investigate the prevalence of Salmonella and Shigella among outpatients in Jimma University Specialized Hospital, Southwest Ethiopia. Cross-sectional study was conducted involving a total of 176 outpatients. Stool specimens from both adult and pediatric outpatients were collected and analyzed for the presence of presumptive Salmonella and Shigella colonies followed by confirmation by biochemical tests.

Despite rigorous effort made to control malaria for more than a century, it is still among the main public health problems in least developed regions of the world. Majority of deaths associated with malaria occur in sub-Sahara Africa among biologically risked groups. Thus, this study was designed to assess the incidence of severe malaria syndromes among children in Pawe Hospital, Northwest Ethiopia.

Background: The quality of drinking water has always been a major health concern, especially in developing countries, where 80% of the disease cases are attributed to inadequate sanitation and use of polluted water. The inaccessibility of potable water to large segment of a population in the rural communities is the major health concern in most part of developing countries. This study was designed to evaluate the physico-chemical and bacteriological qualities of drinking water of different sources in the study area.

Although more emphasis has been given to the genetic and environmental factors that determine host vulnerability to malaria, other factors that might have a crucial role in burdening the disease have not been evaluated yet. Therefore, this study was designed to assess the effect of khat chewing on the incidence of severe malaria syndromes and immune responses during malaria infection in an area where the two problems co-exist. Clinical, physical, demographic, hematological, biochemical and immunological data were collected from Plasmodium falciparum mono-infected malaria patients (age ≥ 10 years) seeking medication in Halaba Kulito and Jimma Health Centers.

Background: The objective of this study was to explore effects of khat (Catha edulis) on outcome of rodent malaria infection and its anti-plasmodial activities on Plasmodium berghei ANKA (PbA).

Methods: Female Swiss albino mice were orally treated with crude khat (Catha edulis) extracts (100, 200 and 300 mg/kg) on a daily basis for 4 weeks prior to PbA infection. Physical, clinical, hematological, biochemical and histo-pathological features of the mice were assessed.
