In Indonesia, schistosomiasis is presently confined to two endemic areas in Central Sulawesi; Lindu (1,500) and Napu (5,000 inhabitants) valleys. Because of various development schemes now underway, it is feared that the natural balance which existed for many years between the parasite, the snail intermediate hosts and man, will be upset and will place some 70,000 people of the adjoining Palu and Palolo areas at risk. Measures are being taken to control and prevent the spread of the disease. A pilot control programme is planned for two years in the village of Anca in Lindu with a population of 391 and a prevalence rate of 70.5%. Langko village with a population of 464 and a prevalence rate of 53.7% will be utilized as the comparison area. Baseline data on human, malacological and animal reservoir hosts are being collected and control operations are anticipated to commence in July 1975. Measures to be applied to control schistosomiasis in the order of priorities are: (a) agro-engineering or modification of the environment; (b) environmental sanitation through the provision of adequate water supply and construction of latrines; (c) mollusciciding of remaining snail infested areas; (d) chemotherapy, and (e) health education campaign. At the end of the two-year control programme, the following activities will be carried out to determine the degree of intervention achieved; (a) human data: calculation of prevalence rates, incidence rates, and changes in the intensity of infection based on quantitative egg counts; (b) malacological data: changes in the number and extent of snail foci; snail density, and snail infection rates; (c) reservoir hosts: changes in the prevalence rates among domestic and wild animals. Calculation of reclaimed areas and increase in agricultural production will also be assessed together with the overall cost/benefit analysis of the project undertaking.
在印度尼西亚，血吸虫病目前局限于中苏拉威西的两个流行区；林杜（1500人）和纳普（5000居民）山谷。由于目前正在实施各种发展计划，人们担心寄生虫、中间宿主蜗牛和人类之间多年来存在的自然平衡将被打破，这会使毗邻的帕卢和帕洛洛地区约7万人面临风险。正在采取措施控制和预防该疾病的传播。计划在林杜的安卡村开展一项为期两年的试点控制项目，该村有391人，患病率为70.5%。将以有464人、患病率为53.7%的朗科村作为对照区。正在收集关于人类、贝类学和动物储存宿主的基线数据，预计控制行动将于1975年7月开始。按优先顺序用于控制血吸虫病的措施有：（a）农业工程或环境改造；（b）通过提供充足的供水和建造厕所进行环境卫生改善；（c）对剩余有螺感染区进行灭螺；（d）化疗；以及（e）开展健康教育活动。在为期两年的控制项目结束时，将开展以下活动以确定所取得的干预程度：（a）人类数据：根据定量虫卵计数计算患病率、发病率以及感染强度的变化；（b）贝类学数据：螺点数量和范围的变化；蜗牛密度以及蜗牛感染率；（c）储存宿主：家畜和野生动物患病率的变化。还将评估开垦面积的计算和农业产量的增加情况，以及该项目的总体成本效益分析。
