First characterization of chikungunya viruses from Indian Ocean outbreak

strains of the virus involved in earlier outbreaks and suggest how the virus could have become more "aggressive". Experiments are now underway to test which of these features might be responsible for the apparent increase in the virus' ability to infect humans and cause disease.

As the authors note, the mosquitoes that transmit the Chikungunya virus in Africa and Asia are not limited to these areas--in fact they are the same ones that transmit yellow fever and dengue fever in many parts of the world--which raises the possibility that the chikungunya virus could spread and cause disease elsewhere.
