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%.
血吸虫病和土壤传播的蠕虫（SSTH）感染是全球范围内的一个主要健康问题，但疾病负担在热带国家。该病在苏丹尼罗河州流行，但确切的患病率尚不清楚。
对苏丹尼罗河州 103 所基础学校的 2490 名学生进行了调查，以确定 SSTH 感染的流行率和分布情况。采集粪便和尿液样本，检查埃及血吸虫、曼氏血吸虫和肠道蠕虫的卵。使用问卷获取人口统计学数据，量化接触地表水的情况，并评估学生和利益攸关方对风险行为和控制策略的看法。
尼罗河州的埃及血吸虫感染率为 1.7%，不同地区的感染率存在差异（范围为 0.58-3.5%）。未发现曼氏血吸虫感染，肠道蠕虫感染率为 0.1%。
