In September 2010, autochthonous transmission of chikungunya virus was recorded in southeastern France, where the Aedes albopictus mosquito vector is present. Sequence analysis of the viral genomes of imported and autochthonous isolates indicated new features for the potential emergence and spread of the virus in Europe.
Chikungunya virus (CHIKV; Togaviridae, genus Alphavirus), transmitted to humans by the bite of Aedes spp. mosquito, leads to an acute fever associated with an arthromyalgic syndrome (1). CHIKV outbreaks occurred after the virus's recent expansion in Africa, the Indian Ocean, India, and Southeast Asia. Phylogenetic analyses have demonstrated 3 distinct lineages of CHIKV strains: West Africa, Asia, and East/Central/South Africa (ECSA) (2,3). Strains from the Indian Ocean and India segregate into 2 independent sublineages that presumably derive from an East African ancestral genotype (2,3). Until recently, the Ae. aegypti mosquito was widely accepted as the main urban vector of CHIKV. However, the Ae. albopictus mosquito was extensively implicated in CHIKV transmission during the 2005–06 outbreak in Réunion Island (1).
