Spatial distribution of Aedes Aegypti focus in Campina Grande, Paraíba

Abstract

The proliferation of Aedes aegypti mosquito has increased in recent years in urban agglomerations, causing successive episodes of epidemics throughout the country. Some factors contribute to the proliferation of the Aedes egypti mosquito, such as water scarcity and lack of coverage from supply network. Given the above, this work aimed to analyse the spatial distribution of Aedes Egypti focus in the neighbours of Campina Grande/PB, due to the failures in water supply networks. The research methodology used in this work is based in a epidemiological study with an ecological outline and a quantitative approach. Through spatial analysis it was observed a negative and positive spatial autocorrelation in some of the neighbours of Campina Grande. The positive spatial autocorrelation warns to an increase of indications of Aedes aegypti larvas in specific neighbours. This fact is a result from the permanence of ground-level deposits used for water storage. In this sense, it is observed that the visualization of these locations shows the environmental vulnerability of these areas, and the probability of the population of these neighborhoods being susceptible to diseases transmitted by Aedes aegypti. Therefore, the need to invest in the efficient management of the water use of the Epitácio Pessoa reservoir is emphasized, thus ensuring the regularization of supply without the need for water storage.
