Bayesian skyline plot (BSP) of (a) 176-sequence dataset and (b) Taiwan strains isolated during 2003–2008 The x-axis is the time scale in years, and the y-axis is a logarithmic scale of Neτ (where Ne is the effective population size and τ is the generation time). The thick solid line indicates the median estimates, and the shaded area indicates the 95 % HPD
