Variabilidade climática e casos de dengue em municípios do Estado da Paraíba, Brasil.

Abstract

The present work has the objective to correlate the precipitation and air temperature meteorological variables to the reported cases of dengue in municipalities of the State of Paraíba, from 2007 to 2017. Paraíba presents a climatic variability due to physical and atmospheric factors, thus the Variations in precipitation and air temperature are conditions that favor the increase of breeding sites and consequently the development of the Aedes Aegypti vector. These climatic elements cause the emergence of mosquitoborne diseases such as dengue. Data obtained from the Notification Disease Information System (SINAN), the Paraiba State Water Management Executive Agency (AESA) and the National Institute of Meteorology (INMET) were spatialized in the QGIS 2.14 software using the IDW method of interpolation. The results showed moderate or low correlation in most years analyzed. In Mata Paraibana there was a high incidence rate for Cabedelo and João Pessoa. In Agreste stands out Campina Grande with rates ranging from low to medium incidence throughout the period analyzed. In 2013, 2015 and 2016 there was a predominance of high incidence and epidemic rates of reported dengue cases, with precipitation of less than 400 mm in the Borborema mesoregion, with the municipality of Monteiro presenting epidemic rates during most of the period. Sertão Paraibano was similar to Borborema in the incidence rates of notified dengue cases, especially in the city of Catolé do Rocha, due to the high incidence of notification rates throughout the study period.
