A Ocorrência de dengue no Mato Grosso do Sul: uma análise do ótimo climático nas cidades de Campo Grande, Corumbá, Dourados e Três Lagoas

Abstract

The present study consists of understanding the geographic distribution of dengue in different climatic units, according to the Zavattini classification (2009), in the state of Mato Grosso do Sul. Four cities were selected: Campo Grande, Corumbá, Dourados and Três Lagoas, between the years 2007 and 2008, which consist of an epidemic and not an epidemic respectively. The focus of the research is the understanding of the influence of climatic aspects on the life cycle of the mosquito Aedes aegypti, which is the main transmitter of the disease. For this, an analysis of climatic optimism in cities is carried out through modeling tools and Geographic Information Systems (GIS). The analysis showed that climatic aspects are essential for the good development of the vector of the disease, but the way of life of the population, mainly related to waste disposal, is a facilitator for dengue epidemics. The results thus demonstrate the complexity of the disease and the close relationship between environment and population. An important point to make is that even in different climatic units, the epidemic followed a similar pattern, which reaffirms the importance of climatic variables in understanding the entire epidemiological process. Corumbá was the city that presented a distinct pattern, not following the notifications of the entire state, because its proximity to Bolivia leaves it vulnerable to the entry of new serotypes, demanding extra attention. The results seek to assist health services in an attempt to prevent further epidemics.
