Efeitos de alterações térmicas e pluviométricas na incidência de arboviroses

Abstract

This study analyzed the literature on meteorological changes, such as temperature and rainfall, and their possible impacts on the increase in arboviruses cases in Brazil (2013-2024). The research base included government agencies, climatological research institutions, legislation, and databases such as SciELO and PubMed. The analysis of studies and meteorological bulletins (from INMET) demonstrates that during the studied period there was a significant increase in temperature in the country, influenced by climatological phenomena, as well as an increase in cases of dengue, Zika virus, and Chikungunya. The authors’ studies conclude that precipitation and temperature have a significant influence on the ecology of the Aedes aegypti vector, as well as the previous circulation of the virus, disordered urbanization, and increased human circulation. Given this scenario, it is noted that arboviruses outbreaks are favored by abiotic factors and that health surveillance plays a fundamental role in prevention, both in control actions and in the training of health professionals. Understanding vector-climatology dynamics is fundamental for public policies to coordinate proactive actions to address epidemic scenarios.
