Tropical UrologyReviewPrevalence of urinary schistosomiasis in Nigeria, 1994-2015: Systematic review and meta-analysis

IntroductionThe Global significance of schistosomiasis started waning over the years owing to its eradication in most developed societies, until the reawaking of global attention and it now occupies a prominent place amongst the neglected tropical diseases (NTD). The aim of our study was to accurately estimate the prevalence of schistosomiasis in Nigeria, and its six geo-political zones.Subjects and methodsWe utilized electronic databases to search and select studies on prevalence across the geographical zones between 1994 and 2015. STATA 10 Random effects meta-analysis of observational studies was used to generate our estimates.ResultSixty-seven studies met the inclusion criteria. The unified pooled population studied was 47,440 (n = 14,888 persons). The pooled prevalence]) of Schistosoma haematobium infestation was, for all regions = 34.7% (31.0-38.5) (95% confidence interval [CI)).ConclusionSchistosomal infestations remain hyperendemic in Nigeria. Nigeria must, therefore, expedite the execution of resolution WHA66.12 adopted by the World Health Assembly on NTD.
