Dengue is an acute febrile viral disease caused by infection with one of the four dengue virus serotypes (DENV-1, 2, 3 and 4) that is transmitted to humans by the mosquito Aedes aegypti. In the present study identified genotypes and line ages of the four dengue virus serotypes from isolates from different geographic regions of Peru from 1998 - 2012. Design of the study was descriptive – retrospective of the genetic features, 109 strains belonging to one of the four dengue virus serotypes were processed by RT-Nested PCR to amplify the gene region E/NS1 and sequenced the full genome of a strain of DENV-2. Sequences were aligned with the program CLUSTAL X and analyzed with the software MEGA 5.0 with the Neighbor-Joining distance algorithm for E/NS1 and Maximum Likelihood method for full genome. Was identified serotype DENV-1, genotype V, with three lineages; respect to serotype DENV-2, were described two genotypes: genotype America with two lineages and genotype Americas/Asia with five lineages. DENV-3 genotype III presented the five lineages and ultimately was found DENV-4 with two lineages. We conclude that the four serotypes of dengue viruses isolated in different geographical areas of Peru during 1998 - 2012 showed genetic variation at the level of genotypes and lineages, DENV-3 remains the most divergent with five lineages and least divergent DENV-4 with two lineages, compared to the other serotypes examined. Keywords: dengue virus, dengue virus serotype, viral genotype, viral lineage, viral genome.
