Abstract__ Chikungunya has resurged in the form of unprecedented explosive epidemic in 2006 after a long gap in India affecting million of persons. The disease continued for the next two consecutive years affecting 59 535 and 64 548 persons during 2007 and 2008 respectively. The 2008 outbreak being the second largest among these three years the information regarding the etiology and the mutations involved are useful for further control measures. Among the 2008 outbreaks the Coastal Karnataka accounts for the 46 510 persons. An in-depth investigation of Chikungunya epidemic of Coastal Karnataka India 2008 by serology virus isolation RT-PCR and genome sequencing revealed the presence and continued circulation of A226V mutant Chikungunya virus. The appearance of this mutant virus was found to be associated with higher prevalence of vector Aedes albopictus
