Resumo: Independent outbreaks of dengue virus (DENV) infection - sporadic cases of chikungunya virus (CHIKV) have been recorded in the metropolitan city of Delhi on several occasions in the past. However, during a recent 2010 arboviral outbreak in Delhi many cases turned negative for DENV. This prompted us to use duplex reverse transcriptase-polymerase chain reaction (D-RT-PCR) to establish the aetiology of dengue/chikungunya through sequencing of CprM - E1 genes of dengue - chikungunya viruses. Interestingly, for the first time, both DENV - CHIKV co-circulated simultaneously - in equally dominant proportion during the post-monsoon period of 2010. DENV-1 genotype III - the East Central South African genotype of CHIKV were associated with post-monsoon spread of these viruses.
