Review on Schistosomiasis: Epidemiology and Clinical Manifestation up to Date (original) (raw)

International Journal of Medical Parasitology and Epidemiology Sciences

Schistosomiasis is a parasite disease that affects both humans and animals and is brought on by the blood flukes of the genus Schistosoma. It is one of the world’s most enduring neglected tropical diseases. Sub-Saharians make up more than 90% of them, and a significant portion of Ethiopians are afflicted and at risk. It spread across the entire nation and was correlated with the rapid development of water resources and population growth. The two species of freshwater snails, Biomphalaria pfeifferi and Biomphalaria sudanica, are responsible for the parasite’s transmission in Ethiopia. Compared to the three primary schistosomes that infect people, Schistosoma mansoni, Schistosoma haematobium, Schistosoma japonicum, Schistosoma intercalatum, and Schistosoma mekongi have less of an epidemiological impact. Geographically, S. haematobium and S. mansoni are more common in Africa than other species. Epidemiological coverage is also influenced by seasonal distributions throughout the postrai...

Clinico-epidemiology, malacology and community awareness of Schistosoma mansoni in Haradenaba and Dertoramis kebeles in Bedeno district, eastern Ethiopia

SAGE Open Medicine, 2018

Background: Schistosoma mansoni is a major public health problem. Different studies reported unidentified sites in Ethiopia with variable prevalence and intensity, but there is no report from this study area. Objective: To assess the clinico-epidemiology, malacology, risk factors, and community awareness of S. mansoni in Haradenaba and Dertoramis kebeles in the Bedeno district, eastern Ethiopia. Methods: A cross-sectional study was conducted among 1011 study participants in 413 systematically selected households from Haradenaba and Dertoramis kebeles from 30 June 2016 to 30 July 2017. Data were collected by using pretested, structured questionnaires, clinical examinations, and stool examinations. Stool samples were processed by the Kato-Katz method and examined microscopically. Snails were collected by scooping from water contact points. Data were analyzed using SPSS, version 16 statistical software. Result: The overall prevalence of S. mansoni was 35.7%. Heavy-intensity infection w...

Schistosomiasis mansoni focus in Mekele City, northern Ethiopia

Ethiopian medical journal

Intestinal schistosomiasis due to Schistosoma mansoni is prevalent and widely distributed in Ethiopia. The disease continues to spread to previously non-endemic areas mainly in connection with water resource development and population movement. To assess the transmission and magnitude of Schistosoma mansoni infection among school children in Addisalem and Lachi Primary Schools in Mekele City, northern Ethiopia. A cross-sectional study was carried out in two primary schools in Mekele City in March 2011. Stool specimens were collected and processed for quantitative microscopic examination using Kato-Katz technique and ova were quantified Search for intermediate snail hosts was carried out in Elala stream and collected snails were examined for trematode infection by shedding after they were individually exposed to electric light for about one to two hours. The overall prevalence of S. mansoni infection was 26.3% and for those infected with S. mansoni the mean intensity of infection was...
