Dengue incidence trend in Brazil, 2002-2012.

OBJECTIVE to analyze dengue incidence trend in Brazil from 2002 to 2012. METHODS this was an ecological study with data of the Information System for Notifiable Diseases (Sinan); the incidence rate was calculated by age groups, states and macroregions, through Prais-Winsten regression. RESULTS dengue incidence rates in Brazil, in 2002 and 2012, were of 401.6 and 301.5 per 100,000 inhabitants, respectively; annual increment rates were stable (21.4%; 95%CI -19.8;83.7) in most of the states, except for Alagoas (38.9%; 95%CI 5.1;83.5) and Tocantins (50.4%; 95%CI 12.6;100.7); the North Region was the only region to present increase trend in the incidence of dengue. CONCLUSION although rates have remained stable in most of the states, they are still high in Brazil; broader public policies focusing on new dengue control strategies are necessary.
