Figure 6. The reconstructed Bayesian skyline plot of the history of Heyuan HCV 2a and 6a clusters.

Figure 6

Bayesian skyline plot was reconstructed to estimate the effective infection numbers of Heyuan 2a cluster (A) and 6a cluster (B). X-axis is the year of the infection, Y-axis indicates the estimated HCV infection population size. Black line represents the estimated effective population size through time. The blue area represents the 95% upper and lower highest posterior density (HPD) confidence intervals for this estimate.
