Clima e Saúde: Vulnerabilidade Climática e Ocorrência de Dengue em Municípios do Semiárido Paraibano (2014-2024).

Abstract

Human activities affect the environment in a variety of ways, especially when it comes to climate change, which adds additional stress to existing global problems such as malnutrition, endemic infectious diseases, and accidents caused by extreme events. Climate change also causes significant harm to human health by influencing the behavior of certain diseases, such as vector-borne diseases, altering their biogeochemical cycles and ecosystems. The objective of this study is to establish a connection between dengue cases in three municipalities in Paraíba: Patos, Mãe d'Água, and Campina Grande, relating them to the climatic elements of precipitation and average temperature from 2014 to 2024. To this end, the following procedures will be carried out: a) a baseline survey; b) an exploratory and comparative study between climatic factors and these morbidities; c) a survey and analysis of epidemiological data; d) a spatial distribution of results. Therefore, the study's initial hypothesis was confirmed: climate variations are related to the occurrence of dengue in these three municipalities. Furthermore, factors such as a lack of environmental education for the population, poor epidemiological surveillance, areas contaminated with solid waste, and inadequate basic sanitation contribute to the maintenance of conditions conducive to the proliferation of vectors. The conclusion is that this study can be used as a basis for effective decisions and strategies that fully serve the population.
