Erratum to “A Bioinformatics Pipeline for the Analyses of Viral Escape Dynamics and Host Immune Responses during an Infection”

A representative example of a HCV infection presenting highly diverse viral population. Single genome amplification (SGA) data from longitudinally collected HCV populations over three time points (2, 3, and 4WPI) taken from a subject (10012) infected with HCV genotype 1a. This analysis was based on sequences from partial Core protein, p7, E1, and E2 protein, of HCV from 2WPI and 4WPI (3WPI not shown). Unrooted phylogenetic tree displays three major subpopulations of viruses. A substantial viral diversification is observed since 2 weeks after infection. During this early stage of infection it is unlikely that HCV specific T-cell and B-cell responses are targeting the infection. However, the Circos plots highlight the presence of highly connected variants with specific patterns of cooccurring mutations. This is further validated from the covariance network showing high number of pairs of sites, which are maintained during the early phase of infection.
