Techniques that can be used to monitor changes in morbidity in large scale control schemes carried out through the PHC structure by a local health administration differ from those that can be used in well funded, small scale research programmes. Above all they must be cheap, simple, rapid and objective. They should demonstrate the effects of intervention soon after it has taken place and be directed to phenomena that have high prevalences. Monitoring of liver and spleen size in S. mansoni foci to some extent meets these criteria but can only be seen as an adjunct to quantitative microscopy. Urinalysis with reagent strips, or even simpler methods, may have a more important role in evaluating control of urinary schistosomiasis and practical constraints may make it easier to carry out than quantitative microscopy. However, the latter conveys more information and is of greater value in planning and urinalysis must be seen as an inadequate substitute for quantitative microscopy.
当地卫生行政部门通过初级卫生保健结构实施的大规模防治计划中，用于监测发病率变化的技术，与资金充足的小规模研究项目中所使用的技术有所不同。最重要的是，这些技术必须廉价、简单、快速且客观。它们应在干预措施实施后不久就显示出效果，并针对高流行率的现象。在曼氏血吸虫病疫区监测肝脏和脾脏大小在一定程度上符合这些标准，但只能视为定量显微镜检查的辅助手段。使用试剂条进行尿液分析，甚至更简单的方法，在评估埃及血吸虫病防治效果方面可能发挥更重要的作用，而且实际操作限制可能使尿液分析比定量显微镜检查更容易实施。然而，定量显微镜检查能传达更多信息，在规划中更具价值，尿液分析必须被视为定量显微镜检查的不充分替代品。
