Relação das variáveis hidrometeorológicas com os casos de malária nos Municípios da Bacia do Rio Negro-AM

Abstract

Malaria is a high-risk infectious disease that causes great concern and high costs to public health, especially in tropical and subtropical regions of the world. The Amazon region has a high endemic rate of malaria, in which its hydrometeorological characteristics are preponderant for longevity, vector density of the transmitter and the reproduction of the pathological agent of the disease. It becomes important, diagnose how the hydrometeorological conditions of each region are associated with the occurrences of malaria and understand how the variability of these conditions are associated, with the incidence of the disease. The objective of this work is to analyze the influence of the conditions hydrometeorological conditions and their variability in the incidence of malaria cases in the municipalities of Manaus, Barcelos and São Gabriel da Cachoeira, which are bathed by the Negro River, in the State of Amazonas. The results show that during the driest period in the region, the malaria cases are more prevalent, this relationship is observed by Pearson's correlation coefficient, where precipitation, relative air humidity and the height of the Rio Negro showed a moderate and negative correlation with the incidence of malaria, and temperature showed a positive and moderate correlation with the incidence of malaria. The analysis for the ENSO event shows that the variability caused in the hydrometeorological elements, can potentiate/attenuate the incidence of malaria.
