ARAUJO, Fernanda Montenegro de Carvalho et al. Concurrent infection with dengue virus type-2 and DENV-3 in a patient from Ceará, Brazil. Mem. Inst. Oswaldo Cruz [online]. 2006, vol.101, n.8, pp. 925-928. ISSN 1678-8060. http://dx.doi.org/10.1590/S0074-02762006000800017.
Dengue outbreaks have occurred in several regions in Brazil and cocirculating dengue virus type 1 (DENV-1), DENV-2, and DENV-3 have been frequently observed. Dual infection by DENV-2 and DENV-3 was identified by type-specific indirect immunofluorescence assay and confirmed by reverse transcription polymerase chain reaction in a patient in Ceará with a mild disease. This is the first documented case of simultaneous infection with DENV-2 and DENV-3 in Brazil. Sequencing confirmed DENV-2 and DENV-3 (South-East/American) genotype III and (SriLanka/India), genotype III respectively.
