Abstract

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.
