Molecular characterization of chikungunya virus circulating in urban and rural areas of West Bengal, India after its re-emergence in 2006

Conclusions Two sub-lineages of East-central-southern African (ECSA) genotype of CHIKV strains were circulating simultaneously in this state during the study period; one type was circulating in rural areas of the state from 2006 whereas another type was isolated from the metropolitan city of Kolkata in 2011 and 2012. The mutational pattern of those CHIKV strains suggests that the transmission of the viruses might be facilitated by different species of Aedes mosquitoes. Our results represent an important first step towards understanding the circulating strains of CHIKV in the state of West Bengal with the geographical variation.
