Abstract
Introduction: This study was carried out to analyze the temporal evolution of the incidence of dengue in Araraquara-SP, Brazil, from 2012 to 2016, correlating the incidence with temperature and pluviometry. Methods: It was a cross-sectional design. The monthly number of cases from 2012 to 2016 was collected in the datafile of the Special Health Service of Araraquara-SESA of USP. Climatic variables related to temperature and rainfall were obtained from the websites of Agritempo and Department of Water and Electric Power, respectively. Statistical planning included incidence rates, and the tendency from 2012 to 2016, and it was studied the correlation between the number of dengue cases and each one of the climatic variables, considering the time-lag concept. Results: The incidence rates were 52.68, 376.52, 737.39, 3,660 and 809.48 per 100,000 inhabitants. Significant correlations were observed between the number of dengue cases and climatic variables after 2-4 months for high temperature and after 1-4 months for rainfall. Conclusions: The city faced an epidemic of dengue in 2015. It was identified the time lag in which hot weather and rain favored the occurrence of new cases: 2 to 4 months later for high temperature, and 1 to 4 months later for rainfall.
Highlights
This study was carried out to analyze the temporal evolution of the incidence of dengue in Araraquara-SP, Brazil, from 2012 to 2016, correlating the incidence with temperature and pluviometry
A dengue fever epidemic outbreak occurred in the Southeast city of Araraquara, in the state of São Paulo, with 8,296 autochthonous cases reported, and an incidence rate of 3,660 cases per 100,000
To examine the role of climatic conditions in the incidence of dengue fever in the city of Araraquara from 2013 to 2015 (10,850 confirmed cases) and increasing annual incidence rates during this period, we conducted a comparative study to assess the correlation between the incidence of dengue and seasonal climatic conditions for the period 2013-2015 and including 2016
Summary
This study was carried out to analyze the temporal evolution of the incidence of dengue in Araraquara-SP, Brazil, from 2012 to 2016, correlating the incidence with temperature and pluviometry. In many areas of the Brazilian territory dengue fever cases have been associated with high rainfall and temperature seasonal variation as these conditions contribute to an increase in the number of mosquito breeding sites. It is necessary to know the temporal trends of dengue incidence as well as its main aspects such as occurrence during a specific time of the year because dengue fever is characterized by recurrent cycles consistent with seasonal variations of rainy and dry periods and temperatures This knowledge will help developing public policies aiming at surveillance that is more effective and control of dengue in the city. This study was undertaken to verify the temporal evolution of the incidence of dengue in the city of Araraquara-SP, Brazil for the period 2012–2016, and to assess the correlation between incidence and the climatic variables (temperature and rainfall)
