Abstract

Background: Leptospirosis is a serious zoonosis. In 2024, Rio Grande do Sul (RS) experienced floods affecting 93% of the municipalities and 8.8% of the population. In this study, we reviewed the leptospirosis notifications post-flooding.

Methods: Descriptive quantitative study using secondary data from the RS Health Department Epidemiological Report.

Results: A total of 7,129 suspected cases were reported, of which 788 were confirmed. Porto Alegre had the highest number of cases and Travesseiro had the highest incidence rate. Epidemiological weeks 20-24 peaked in cases and deaths (47 total cases), with significant municipal variation.

Conclusions: The 2024 floods caused a significant increase in leptospirosis, underscoring the need for a One Health approach and strengthening public health policies.

2024年洪水期间南巴西大德州钩端螺旋体病的流行病学方面。

背景：钩端螺旋体病是一种严重的人畜共患病。在2024年，巴西南格兰德州（RS）经历了洪水，影响了93%的城市和8.8%的人口。在本研究中，我们回顾了洪水后钩端螺旋体病的报告。方法：采用RS卫生部流行病学报告的二手资料进行描述性定量研究。结果：共报告疑似病例7129例，确诊病例788例。阿雷格里港的病例数最多，特拉韦塞罗的发病率最高。20-24流行病学周的病例和死亡达到高峰（总共47例），各城市差异很大。结论：2024年洪水导致钩端螺旋体病显著增加，强调了“同一个健康”方针和加强公共卫生政策的必要性。
