An analysis of the Chikungunya virus' s genetic code suggests that the increased severity of the 2005–present outbreak may be due to a change in the genetic sequence, altering the virus' viral coat protein, which potentially allows it to multiply more easily in mosquito cells and utilise the Asian tiger mosquito as a vector in addition to the more strictly tropical main vector, Aedes aegypti. Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In July 2006, a team analyzed the virus' RNA and determined the genetic changes that have occurred in various strains of the virus and identified those genetic sequences which led to the increased virulence of recent strains.
