Dengue occurrence is partially influenced by the immune status of the population. Consequently, the introduction of a new Dengue virus serotype can trigger explosive epidemics in susceptible populations. The determination of clusters in this scenario can help to identify hotspots and understand the disease dispersion regardless of the influence of the population herd immunity.

Methods: This cross-sectional study included data from dengue cases with serotyping results that occurred between 2009 and 2013 in Vitória, EspÃrito Santo, Brazil.
Introduction: The article describes the epidemiologic profile of dengue cases in Vitória, the capital of EspÃrito Santo, Brazil, from 2000 to 2009, aimed at identifying risk groups regarding the incidence and severity of the disease.
Methods: Confirmed cases of dengue among city residents during ten years were classified as dengue fever, dengue hemorrhagic fever, dengue shock syndrome and dengue with complications, and analyzed according to sex, age, race-color and education.
Results: The proportion of dengue cases was highest among women aged 20 to 29 years-old and similar between whites and blacks.
