History of dengue in Brazil is covered from the first citations in the XIXth century to the great outbreaks of the last ten years. DEN-1 and DEN-4 viruses have been isolated for the first time in 1982 during an epidemic in Boa Vista, Roraima State. In 1986-1987, epidemics of dengue type 1 covered an extended area from Rio de Janeiro/Sào Paulo States to the North East States of Brazil. During 1990-1991, dengue type 2 epidemics bave been notified in the South East (Rio de Janeiro/São Paulo) and in some States of the interior of the country (Mato Grosso do Sul, Tocantins). DEN-1 virus was also circulating the same year in São Paulo and Minas Gerais States. Recently (1994), an important outbreak bas been studied in Ceará State, where DEN-2 and DEN-1 viruses bave been isolated. In Rio de Janeiro and Ceara (1990 and 1994, respectively), it is probably the succession of infections by DEN-1 and DEN-2 viruses which has caused many DHF/DSS cases. The urban vector has always been the mosquito Aedes aegypti, from which 4, 7 and 16 strains of DEN-4, DEN-1 and DEN-2 have been isolated, respectively. In Brazil, transovarial transmission of dengue viruses by this species has not yet been shown to occur in nature.
