IMPACT ASSESSMENT OF RAINFALL ON THE INCIDENCE OF DENGUE IN AMAZONAS

Abstract

The objective of this study was to evaluate the impact of rainfall on the incidence of dengue in Amazonas, considering the influence of climatic conditions on public health. The methodology adopted was a narrative literature review, which selected articles and reports published between 2020 and 2025. These documents were obtained from scientific databases such as SciELO, PubMed, LILACS, and Google Scholar, as well as reports from the Amazonas Health Surveillance Foundation and the Ministry of Health, published on their respective platforms. The results indicated a correlation between intense rainfall and the increased proliferation of the Aedes aegypti mosquito, which contributes to the rise in dengue cases, especially during the rainy season. During this period, an increase in breeding sites was observed, resulting in larger outbreaks. The review of rainfall and epidemiological data showed that the combination of constant monitoring and preventive measures can improve the response to outbreaks and reduce the impacts of dengue on local public health. The conclusion points out that the seasonality of the disease requires continuous control and monitoring strategies, highlighting the importance of predictive technologies, such as early warning systems, and innovative methods, such as genetically modified mosquitoes.
