Chikungunya and Dengue are two major emerging viral infections. The changing pattern of these diseases is of major concern due to their rapid spread and increased virulence. Both of them are arthropod-borne RNA viruses, transmitted by Aedes mosquitoes. Chikungunya, which was considered to have disappeared from India and the South-East Asian countries, remerged as an explosive out-break during the years 2005-2007. Kerala witnessed three sequential out breaks of the disease during 2006, 2007, 2008 and 2009. Dengue has become endemic to the state and molecular studies on the biology of local virus isolates have not been attempted. The key focus of our research includes genetic characterization of the local isolates of these viruses and understanding the effect of gene level alterations in viral virulence and pathogenicity. We are also into development of rapid diagnostic assays for early and sensitive detection of these infections and development of virus inhibitor screens to identify potential anti-viral molecules from natural products.
