To identify the frequency of schistosoma mansoni as a cause of bloody stool or diarrhea and study the clinical, laboratory, radiological characteristics and regional distribution in Hajjah governorate.
This was a hospital based study conducted in Hajjah town, from April 1997 to May 1999. Medical charts were reviewed for age, sex, area of residency, clinical presentation, number of previous schistosoma mansoni infections, possible causes of bloody stool or diarrhea, number of hospital visits and results of any radiological studies made.
Three hundred and sixty patients presented to the pediatric clinic with a history of bloody stool, 156 (43%) with schistosoma mansoni, older children formed 83% and boys 79.5%. Ninety five and a half per cent were from Hajjah governorate, 67% were from Hajjah town. Previous schistosoma mansoni infection was found in 19% and in 20% there was other associated parasitic infestation.
Schistosoma mansoni is a major health problem in Hajjah governorate. Older boys were the most at risk group. Patients in rural regions had difficulties in reaching the hospital, indicated by their low percentage compared to patients from urban areas.
确定曼氏血吸虫作为血便或腹泻病因的出现频率，并研究哈杰省的临床、实验室、放射学特征及区域分布情况。
这是一项于1997年4月至1999年5月在哈杰镇开展的以医院为基础的研究。查阅病历以获取年龄、性别、居住地区、临床表现、既往曼氏血吸虫感染次数、血便或腹泻的可能病因、就诊次数以及所做任何放射学检查的结果。
360名患儿因血便病史前往儿科诊所就诊，其中156例（43%）感染曼氏血吸虫，年龄较大的儿童占83%，男孩占79.5%。95.5%来自哈杰省，67%来自哈杰镇。19%的患儿既往有曼氏血吸虫感染，20%有其他相关寄生虫感染。
曼氏血吸虫是哈杰省的一个主要健康问题。年龄较大的男孩是风险最高的群体。农村地区的患者就医困难，与城市地区患者相比比例较低即表明了这一点。
