With the aim of identifying the etiology of acute febrile illness in patients suspected of having dengue, yet with non reagent serum, a descriptive study was conducted with 144 people using secondary serum samples collected during convalescence. The study was conducted between January and May of 2008. All the exams were re-tested for dengue, which was confirmed in 11.8% (n = 17); the samples that remained negative for dengue (n = 127) were tested for rubella, with 3.9% (n = 5) positive results. Among those non reactive for rubella (n = 122), tests were made for leptospirosis and hantavirus. Positive tests for leptospirosis were 13.9% (n = 17) and none for hantavirus. Non reactive results (70.8%) were considered as Indefinite Febrile Illness (IFI). Low schooling was statistically associated with dengue, rubella and leptospirosis (p = 0.009), dyspnea was statistically associated with dengue and leptospirosis (p = 0.012), and exanthem/petechia with dengue and rubella (p = 0.001). Among those with leptospirosis, activities in empty or vacant lots showed statistical association with the disease (p = 0.013). Syndromic surveillance was shown to be an important tool in the etiologic identification of IFI in the Federal District of Brazil.
Com o objetivo de identificar a etiologia de doenças febris agudas, em suspeitos de dengue com sorologia não reagente, realizou-se estudo descritivo com 144 pessoas utilizando amostras de soro coletados na convalescença, entre janeiro e março de 2008. Todos os exames foram re-testados para dengue, sendo as amostras negativas, processadas para rubéola (n = 127). Dentre as não reagentes para rubéola, submeteu-se ao teste para leptospirose (n = 122), e em se permanecendo sem diagnóstico, testou-se para hantavirose. Confirmou-se dengue em 11,8% (n = 17), rubéola em 3,9% (n = 5) e leptospirose em 13,9% (n = 17). Os resultados não reagentes foram considerados como doença febril aguda indiferenciada (DFI) em 70.8% dos casos. Verificou-se associação estatística em baixa escolaridade nos casos de dengue, rubéola e leptospirose (p = 0,009), assim como dispnéia para dengue e leptospirose (p = 0,012), e exantema/petéquias para dengue e rubéola (p = 0,001). Dentre os doentes com leptospirose, as atividades em terreno baldio mostraram-se com diferença estatística significante (p = 0,013). A vigilância sindrômica demonstrou-se como importante ferramenta na identificação de doenças febris agudas no Distrito Federal.
