Figure 2: A phylogenetic tree of chikungunya virus E1 gene sequences of 2017 (with circle symbol and in bold) was constructed by using the maximum likelihood method based on the Tamura-Nei model in MEGA5 software. The analysis involved four chikungunya virus E1 gene sequences (with triangle symbol) of 2016 and one (with diamond symbol) of 2011 submitted from Jabalpur, India, and other 38 reference sequences downloaded from National Center for Biotechnology Information database. The strains are represented by their GenBank accession number followed by the country of origin along with State and city followed by the year. Onyong-nyong virus was used as the outgroup.
