通过对钩端螺旋体病病例进行空间分析并结合地理信息系统 (GIS) 中的人口和环境数据，对 1996 年夏季里约热内卢西部地区钩端螺旋体病爆发的环境和社会背景进行了检查。钩端螺旋体病病例集中居住地与本地区其他地方存在显着差异。供水覆盖范围、固体废物收集、污水处理系统覆盖范围和洪水风险区域是最初列出的十个变量中的主要决定变量。这些不利的社会和环境因素的影响在距离钩端螺旋体病病例居住地数百米的地方得到了证实，这表明有必要扩大健康监测实践的范围。地理编码表明，一些病例没有报告与洪水接触，尽管它们在地理上与报告有这种接触的病例相邻。病例可能只报告他们认为与疾病相关的暴露情况。地理编码是评估曝光回忆中此类偏差的有用工具。
The environmental and social context in which a leptospirosis outbreak took place during the summer of 1996 in the Rio de Janeiro Western Region was examined by using spatial analysis of leptospirosis cases merged with population and environmental data in a Geographical Information System (GIS). Important differences were observed between places where residences of leptospirosis cases are concentrated and other places in the region. Water supply coverage, solid waste collection, sewerage system coverage and flood risk area were the main determining variables from an initial list of ten. The influence of these unfavorable social and environmental factors is verified hundreds of meters distant from the leptospirosis case residences, demonstrating a necessity to broaden the area of health surveillance practices. The geocoding indicated that some cases did not report contact with flood water, even though they were geographically adjacent to cases who did report this contact. Cases may only report exposures they believe are related to the disease. Geocoding is a useful tool for evaluating such bias in the exposure recall.
