INFLUENCE OF THE WEATHER ON THE OCCURRENCE OF DENGUE IN A TRIPLE-BORDER BRAZILIAN MUNICIPALITY

ABSTRACT

Objective

to analyze the temporal evolution of the incidence of dengue and its correlation with climatic variables in Foz do Iguaçu, a triple-border Brazilian municipality, in the period from August 2006 to July 2016

Method

a descriptive and analytical study conducted in 2018. Secondary data obtained from the health information systems were used. Time analysis was employed and a simple linear regression test was applied to assess the correlation between the dengue incidence rates and the climatic variables

Results

the epidemic years represented 60% of the period studied. There was a positive correlation between incidence of dengue and mean relative humidity in the air (r=0.276; p=0.025), mean temperature (up to two months before r=0.288; p=0.014) and pluviosity (up to three months before r=0.308; p=0.008)

Conclusion

the climatic variables identified as with a positive relationship can support prediction and control of the dengue epidemic
