*Molecular signatures were based on the analysis of complete amino acid sequence E2-6K-E1 (923 aa). The numbering of amino acid positions refers to the African isolate S27 (GenBank access no. AF369024). Residues in boldface indicate critical aa changes. Letters in parentheses after strain names refer to East/Central/South Africa (a), Asia (b) and West Africa (c) phylogroups. Country names in parentheses identify source of imported case. CHIKV, chikungunya virus.
†The amino acid substitution was unique to France/2010 CHIKV isolates.
