Situation analysis of schistosomiasis and soil-transmitted helminthes in River Nile State, Sudan

Abstract

Infection with schistosomiasis and soil-transmitted helminthes (SSTH) constitutes a major health problem worldwide, yet the burden of disease is in the tropical countries. The disease is endemic in River Nile State, Sudan but the exact prevalence rate is unknown. A survey of 2490 pupils in 103 basic schools in River Nile State, Sudan was conducted to determine the prevalence and distribution of SSTH infections. Stool and urine samples were collected and examined for ova of Schistosoma haematobium, S. mansoni and intestinal worms.Questionnaires were used to obtain demographic data, to quantify exposure to surface waters and to assess the perception of pupils and stakeholders about risk behviours and control strategies. The prevalence of S. haematobium in the River Nile State was 1.7% with variation between localities (range= 0.58-3.5%). No S. mansoni infection was detected and the prevalence rate for intestinal helminthes was 0.1%.
