PREVALENCE OF SCHISTOSOMA HEAMATOBIUM AMONG SCHOOL CHILDREN

Urinary schistosomiasis is a common public health problem in the world caused by infection with Schistosoma haematobium [1]. Individuals may acquire the disease during contact with water containing cercaria of the parasite [2]. S. haematobium is responsible for majority of deaths due to schistosomiasis in the world [3]. The disease is particularly prevalent in sub-Saharan Africa where it is estimated to affect 112 million people [3,4]S. haematobium infection causes haematuria, dysuria, lesions of the bladder, kidney failure, bladder cancer, [5–
9]. Infection also interferes with nutrient uptake and can lead to under nutrition, growth and cognitive development retardation, and pose a serious threat to children’s health, education and productivity [10–13]. The disease is responsible for the death of 150,000 people in sub-Saharan Africa annually due to infection-related bladder problems [3,4].
Urinary Schistosomiasis also called Bilharzias is a parasitic disease caused by a digenetic blood fluke of the genus Schistosoma called Schistosoma haematobium. The disease is the second most prevalent neglected tropical diseases after hookworm (Hottez and Kamath, 2009) and remains an important public health problem globally especially in the Sub-Saharan African. Of the world’s 207 million estimated cases of Schistosomiasis, 93% occur in the Sub-Saharan Africa (192 million) with largest number (29million) in Nigeria followed by United Republic of Tanzania (19million) (Hottez and Kamath, 2009).
Although Schistosoma haematobium infection do not always result in clinical diseases and many
infections are asymptomatic, S. haematobium infection is said to produce bladder wall pathology in
approximately 18million people in Sub-Saharan African and 10million people suffer from hydronephrosis and renal failure (Van der Werf et al.,
2003). A significant percentage of women and men with urinary Schistosomiasis acquire genital ulcers and other lesions (Kjetland et al., 2006). Poor reproductive health including sexual dysfunction and infertility [4].Genital Schistosomiasis has also been incriminated to promote horizontal transmission of development retardation, and pose a serious threat to children’s health, education and productivity [10–13].
Hence there is need to assess its prevalence among school children.

1.3 Objectives of the Study
The major objective of the study is the prevalence of Schistosoma heamatobium among school children.

1.4 Research Question
(1) what is S. heamatobium?
(2) How is it contacted ?
(3) what is its prevalence in the population?
(4) why the need to know its prevalence among school children?

1.5 Significance of the Study
This study gives a clear insight into the prevalence of Schistosoma heamatobium among school children. The findings of this research will serve as a preliminary study to help the concerned authorities know which age group among the children is at higher risk of Schistosoma heamatobium.

1.6 Scope of the study
The research focuses on the prevalence of Schistosoma heamatobium among school children.

1.7 Limitations
Samples were collected from children in selected schools and there was difficulty experienced in collecting the samples because they felt reluctant to give their urine.
