The authors submit a simplified sample survey methodology designed to evaluate prevalence rates of leprosy. The system proposed uses a cluster sampling technique. A cluster is a randomly selected group of households. In each household visited by the epidemiological teams all the inhabitants of the target-group are interviewed and examined. Various samples sizes are used (from 6500 to 12,000 peoples) according to the expected prevalence rate of the studied area. All the new cases detected through these surveys are notified to the National Departments in charge of leprosy programmes. Two surveys are already achieved (Equatorial Guinea, Cameroon), a third one in on the way.
作者们提出了一种简化的抽样调查方法，旨在评估麻风病的患病率。所提议的系统采用整群抽样技术。一个群是一组随机挑选的家庭。在流行病调查小组走访的每个家庭中，对目标群体的所有居民进行访谈和检查。根据研究地区的预期患病率，采用了不同的样本量（从6500人到12000人）。通过这些调查发现的所有新病例都通报给负责麻风病防治项目的国家部门。已经完成了两项调查（赤道几内亚、喀麦隆），第三项调查正在进行中。
