Objectives: Dengue infection is a growing public health problem, with the number of reported cases increasing in the Americas and worldwide. This review characterized the epidemiological and economic burden of dengue in Brazil. Methods: Embase, MEDLINE, evidence-based review databases, and gray literature sources were searched for published literature and surveillance reports on epidemiology (between 2000 and 2019) and costs (between 2009 and 2019) of dengue in Brazil. Studies were included if they reported data on incidence, seroprevalence, serotype distribution, expansion factors, hospitalization, mortality, or costs. Data were summarized descriptively and reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results: A total of 344 publications were included (167 peer-reviewed and 177 gray literature). Dengue outbreaks increased in incidence and frequency, with the highest incidence observed in 2015 at 807 cases per 100,000 population. Outbreaks were related to alternating predominant serotypes. Dengue was more frequent in young adults (aged 20-39 years) and in the Midwest. Cost and societal impacts are substantial and varied across regions, age, and public/private delivery of healthcare services. Conclusion: The burden of dengue in Brazil is increasing and likely underestimated. Therefore, developing and implementing new strategies, including vaccination, is essential to reduce the disease burden. |
