ABSTRACT

Introduction: an early warning surveillance system for epidemic outbreaks could enhance the efficiency of vector control campaigns and either delay or stop the epidemic spread of dengue, reducing the impact of the disease. Objective: describe the effect of weather variables on dengue and its vector, the Aedes aegypti mosquito. Methods: the present retrospective study was conducted in the municipality of Camagüey from January to December 2015. Mean values for the weather variables cloud cover, wind speed, dew point, humidity, temperature and precipitation for this area were obtained from a free web page. Data on feverish cases suspected of dengue infection and immature Aedes aegypti detected in the municipality of Camagüey were obtained from records kept at the Provincial Epidemiology Division. The free software R was used to determine the correlation between weather variables and detection of suspected cases and larval Ae. aegypti. The effect of weather variables on cases and larval Aedes aegypti was assessed by simple linear regression. Results: except for wind speed, weather variables had a positive correlation with suspected cases and larval Ae. aegypti. A linear regression model was used to determine the relationship of weather variables to cases and larval Ae. aegypti. Seasonality of weather variables was observed in the five-year period 2011-2015. Conclusions: a relationship was found between weather variables and dengue and its vector, the Ae. aegypti mosquito.
