A influência das mudanças climáticas nas doenças transmitidas por Aedes aegypti no Brasil

Abstract

Introduction: Climate change is a long-term transformation in temperature and climate patterns, mainly caused by human activities, especially the burning of fossil fuels and deforestation. The increase in temperature resulting from this burning and precipitation leads to the proliferation of the Aedes aegypti mosquito, which is responsible for the transmission of dengue, Zika, Chikungunya and yellow fever, which are diseases called arboviruses. Objectives: To conduct a survey of the literature on the occurrence of diseases transmitted by Ae. aegypti and their relationship with climate change in Brazil. Materials and Methods: The systematic review will be carried out according to the PRISMA methodology. The searches were carried out in the Scielo and Lilacs databases, between the years 2010 to 2023. The searches were conducted using descriptors cataloged in the Health Sciences Descriptor - DeCS and in the Medical Subject Headings - MeSH, in Portuguese and English, contained in the title or abstracts of the studies. The following search strategy was used in all databases: (climate change) AND (Arbovirus) OR (dengue virus) OR (Zika virus). Results: Based on the analysis of five (5) articles that studied the correlation of climate change with the proliferation of the Aedes aegypti mosquito and the incidence of diseases transmitted by it, it was identified that the effects of climate variables impact the incidence of diseases and their epidemiology in Brazil. Conclusion: The main findings evidenced in this systematic review demonstrate that meteorological factors such as temperature, rainfall and air humidity are coefficients that affect the dynamics of Ae. aegypti and consequently the incidence of dengue in Brazil.
