Over the past twenty years, Schistosoma mansoni has apparently replaced Schistosoma haematobium as the more prevalent species of schistosomiasis in the Nile delta. In this paper we show that this change has profound implications for public health strategies, in particular the provision and utilization of diagnostic and treatment services for the Egyptian rural population, and for health education programmes. The processes of providing and seeking treatment for the two forms of schistosomiasis are quite distinct as they have different signs and symptoms and are diagnosed in stool and urine samples respectively. In two Nile delta villages, where S. mansoni has almost completely replaced S. haematobium, we found that health services were geared primarily to S. haematobium, and hence many cases of S. mansoni remain undiagnosed and untreated. One reason for this is that health unit staff and local people lacked detailed knowledge of the two forms of schistosomiasis, indicating the need for health education.
在过去二十年中，曼氏血吸虫显然已取代埃及血吸虫，成为尼罗河三角洲地区更为流行的血吸虫种类。在本文中，我们表明这种变化对公共卫生策略具有深远影响，尤其是对埃及农村人口诊断和治疗服务的提供与利用，以及对健康教育计划而言。针对这两种血吸虫病提供治疗和寻求治疗的过程截然不同，因为它们具有不同的体征和症状，且分别通过粪便和尿液样本进行诊断。在尼罗河三角洲的两个村庄，曼氏血吸虫几乎已完全取代埃及血吸虫，我们发现卫生服务主要针对埃及血吸虫，因此许多曼氏血吸虫病例仍未得到诊断和治疗。原因之一是卫生单位工作人员和当地居民缺乏对这两种血吸虫病的详细了解，这表明需要开展健康教育。
