1992年，对埃及法尤姆省21个农村社区1 109个家庭的7 710名分层随机抽样的个人进行了健康问题单和尿液和粪便寄生虫学检查，以调查该省血吸虫感染的危险因素和变化模式。一个子集，每五个家庭，或1 038名受试者，进行身体和超声波检查，以调查发病率和危险因素。S.血红蛋白含量为0~27.1%，平均为13.7%。几何平均虫卵计数（GMEC）为10.0个虫卵/10 ml尿液。在5 - 25岁的人群中，分层感染率和感染强度为18 - 25%和10 - 15个卵/10 ml尿。在13个社区的居民中检测到曼氏血吸虫，但78.5%的感染集中在一个村庄周围的4个卫星村。S.该省的曼氏菌感染率为4.3%，GMEC为44.0个卵/g粪便。感染任何一种病毒的危险因素是男性发送者，年龄25%。与其他17个村庄和埃兹巴相比，曼索尼感染率。传播S。mansoni在法尤姆是一个焦点，那里也有最高的流行率。在流行病学1、2、3项目调查的各省，然而，泌尿道和肝脏的发病率在该省相对罕见。这可能是由于法尤姆长期实施血吸虫病控制方案，该方案抑制感染强度超过流行率，从而降低了社区发病率。
Health questionnaires and parasitologic examinations of urine and stool were performed upon a stratified random sample of 7,710 individuals from 1,109 households in 21 rural communities in Fayoum Governorate, Egypt in 1992 to investigate the prevalence of risk factors for, and changing pattern of, infection with Schistosoma sp. in the governorate. A subset, every fifth household, or 1,038 subjects, had physical and ultrasound examinations to investigate prevalence of, and risk factors for, morbidity. The prevalence of S. haematobium ranged from 0% to 27.1% and averaged 13.7%. The geometric mean egg count (GMEC) was 10.0 eggs/10 ml of urine. Age-stratified prevalence and intensity of infection were 18-25% and 10-15 eggs/10 ml of urine in those 5-25 years of age. Schistosoma mansoni were detected in inhabitants of 13 communities, but 78.5% of the infections were focally present in a group of 4 satellite hamlets around a single village. The overall prevalence of S. mansoni in the governorate was 4.3% and the GMEC was 44.0 ova/g of stool. Risk factors for infection with either species were male sender, an age 25% S. mansoni infection rates in comparison with the 17 other villages and ezbas. Transmission of S. mansoni is focally well established in Fayoum, which also has the highest prevalence of S. haematobium in the governorates surveyed by the Epidemiology 1, 2, 3 Project. However, both urinary tract and hepatic morbidity are relatively rare in the governorate. This probably results from the long-standing schistosomiasis control program in Fayoum, which suppressed intensity more than prevalence of infection, leading to less community morbidity.
