ResumoThe reemergence of chikungunya virus (CHIKV) has compounded the already existing dengue problem because of clinical similarities - common vector, dem-ing the need for a rapid - specific diagnosis. Thus, dengue chikungunya multiplex reverse transcriptase-polymerase chain reaction (DCmRT-PCR) was developed - validated for simultaneous detection of dengue - chikungunya viral infections - its utility in virus serotyping. Blood samples from 97 suspected dengue - chikungunya cases - 10 healthy controls were subjected to dengue - chikungunya conventional RT-PCR - DCmRT-PCR. Thirty-one of 97 samples were positive for dengue or chikungunya viral RNA by RT-PCR - DCmRT-PCR with 100% concordance. DCmRT-PCR products were cycle sequenced. Seven dengue virus strains were clustered within genotype III of DENV-3 - 4 within genotype III of DENV-1, whereas chikungunya sequences were clustered within the Central/East African genotype. DCmRT-PCR was found to be a potential rapid test for simultaneous detection of dengue - CHIKV in clinical samples along with dengue serotyping.
