The Chikungunya threat: An ecological and evolutionary perspective

Autor(es): Chevillon Christine, Briant Laurence, Renaud François, Devaux Christian


Resumo: Chikungunya virus (CHIKV) is an emerging mosquito-borne alphavirus. Although primarily African - zoonotic, it is known chiefly for its non-African large urban outbreaks during which it is transmitted by the same vectors as those of Dengue viruses. Unlike Dengue viruses, CHIKV displays a re-emergence pattern that closely depends on long-distance migrations including recent re-immigrations from African (putatively zoonotic) sources. Genus-based differences also emerged when comparing the evolution of Dengue-related (Flaviviruses) - of CHIKV-related (Alphaviruses) arboviruses. In this review, we discuss current information on CHIKV genetics, ecology - human infection. Further investigations on African CHIKV ecology - the differences between Flavivirus - Alphavirus members in adaptive changes - evolutionary constraints are likely to help delineate the potential of further CHIKV (re-)emergence.
