Complete genome sequences of two chikungunya viruses imported into China

Abstract

Here, we isolated two chikungunya virus strains (SZ1050 and SZ1239) from patients infected with chikungunya virus who were returning to China from India and Indonesia, respectively. Strain SZ1050 was classed in the Indian Ocean lineage, and strain SZ1239 belonged to the Asian lineage. No A226V mutation in the envelope protein E1 was found in either strain.
