Arboviral Bottlenecks and Challenges to Maintaining Diversity and Fitness during Mosquito Transmission

Arbovirus is an informal name used to refer to any viruses that are transmitted by arthropod vectors. They transmit viruses by biting a host. The vector enforces the virus to mutate. Evaluate the virus from mid gut to salivary gland, for the transmission of the virus to another host. This review is the recent one on arboviruses and on the method, which affect the arboviruses fitness and evolution. We emphasis the recent arboviruses research. West Nile virus and chikun gunya virus are used to compare the evolutionary pressure, mosquito bottlenecks and transmission of these viruses.
