Abstract
Urinary schistosomiasis and Intestinal schistosomiasis caused by schistosoma haematobium and schistosoma mansoni respectively constitute a great occupational hazard in rural areas of developing countries and a major public health problem in Nigeria. Efforts in this study were devoted to establish prevalence of urinary and intestinal schistosomiasis and risk factors in relation to the occurrence of the intermediate snail hosts in Zangon-Kataf LGA. A cross-sectional study was conducted using semi-structured questionnaire to collect anthropogenic data of the individuals. Urine and stool samples were collected from nine hundred and seventy (970) individuals for microscopic analysis for S.haematobium and S. mansoni eggs. Strategic water bodies were visited to establish the existence of intermediate snail hosts, Bulinus and Biomphalaria. A retrospective study was conducted between the periods of September 2004 and December 2010 from the hospital records of St. Lois hospital and General hospital in Zangon-Kataf Local Government headquaters. On the cross-sectional studies, a low prevalence of 10(1.65%) and 5(1.36%) Result was obtained for Schistosoma haematobium and Schistosoma mansoni respectively. Other parasites prevalent were 3(0.81%) for Ascaris lumbricoides and 3(0.81%) for Trichuris trichiura. The intermediate snail host screened were found to be absent in the water bodies in study area. The absence of the intermediate snail hosts in water bodies implies that there might be no active transmission of schistosomiasis in the study area, which could be as a result of the absence of stagnant water bodies, sufficient to support the breeding of the snail intermediate hosts during the period of the study. For the retrospective study, 19(0.56%) cases of S.mansoni infection and 4(0.2%) cases of S. haematobium infection were recorded, with 12 male and 7 female for S. mansoni and 1(0.05%) female and 3 male (0.15%) for S. haematobium. The highest number of cases (260) was of those who had Entamoeba histolytica at 7.76% prevalence. Other intestinal helminths results obtained showed relatively low prevalence (0.62%) with one or more intestinal parasites. The low prevalence result obtained for Schistosoma haematobium and Schistosoma mansoni and the non-existence of intermediate snail hosts of Scistosoma haematobium and Schistosoma mansoni (Bulinus and Biophalaria species) in this study indicates that urinary schistosomiasis and intestinal schistosomiasis is hypoendemic during the period of study in this area.
