Evidence exists that schitosomiasis japonica has been present in China for more than 2,200 years. The first parasitologically confirmed clinical case was reported in 1905. Fragmentary surveys before 1949 suggested that there were 5 million schistosomiasis patients distributed in 138 hsiens (counties); however, a more systematic survey after the founding of the People's Republic showed that these figures represented only 50% of patients and 40% of infected hsiens. Based on the epidemiological pattern and ecological characteristics of the snail intermediate host, endemic areas have been divided into three strata: plain region, mountainous and hill region, and marshland and lake region. Following comprehensive control measures, with stress on applied research and integrating technical work with involvement of the population, in 204 hsiens the snail control programs are now considered to be relatively consolidated and the number of patients needing treatment is relatively few. In the marshland and lake region and mountainous region eradication of schistosomiasis remains a difficult problem.
有证据表明，日本血吸虫病在中国已存在2200多年。1905年报告了首例经寄生虫学确诊的临床病例。1949年前的零星调查表明，有500万血吸虫病患者分布在138个县；然而，中华人民共和国成立后的一项更系统的调查显示，这些数字仅代表患者的50%和受感染县的40%。根据钉螺中间宿主的流行模式和生态特征，流行区被分为三个层次：平原地区、山区和丘陵地区以及沼泽地和湖区。采取综合防治措施，强调应用研究，并将技术工作与群众参与相结合，目前在204个县，灭螺计划被认为相对巩固，需要治疗的患者数量相对较少。在沼泽地和湖区以及山区，血吸虫病的根除仍然是一个难题。
