Despite being considered a neglected, re-emerging and the most widespread zoonotic disease worldwide, human-dog leptospirosis has not been subjected to One Health approach, and neither were its socioeconomic and environmental risk factors, as well as concomitant spatial analysis over time. Accordingly, notified human leptospirosis cases, incidence rate and urban hotspot areas, in addition to a systematic review of dog leptospirosis cases, were performed nationwide from 2001 to 2020 in Brazil. Data on Gross Domestic Product (GDP), flooding and study areas were also assessed and tabulated. Human-dog leptospirosis cases were simultaneously mapped with overlapping flooding areas, along with the main circulant serovars. Comparative outcome has shown that dogs may be exposed similarly to humans, becoming important sentinels and/or reservoirs for human leptospirosis in larger geographic areas. Moreover, the study herein can help in the decision and implementation of public policies in Brazil and may serve as a model for other tropical countries worldwide.
尽管犬型钩端螺旋体病被认为是一种被忽视的、再度出现且在全球范围内传播最广的人畜共患病，但人类犬型钩端螺旋体病尚未采用“同一健康”方法，其社会经济和环境风险因素以及随时间的伴随空间分析也未采用该方法。因此，2001年至2020年期间在巴西全国范围内对报告的人类钩端螺旋体病病例、发病率和城市热点地区进行了调查，此外还对犬型钩端螺旋体病病例进行了系统回顾。国内生产总值（GDP）、洪水和研究区域的数据也进行了评估和制表。将人类犬型钩端螺旋体病病例与洪水重叠区域以及主要流行血清型同时进行了绘图。比较结果表明，狗可能与人类有相似的接触，在更大的地理区域成为人类钩端螺旋体病的重要哨兵和/或宿主。此外，本文的研究有助于巴西公共政策的决策和实施，并可作为全球其他热带国家的一个范例。
