Figure 1a consists of two pie charts showing the overall distribution of rotavirus G and P genotypes identified in Australian children (5 years of age or younger) based on vaccine usage for 2013. In part A, the genotypes identified in locations where Rotarix is used are depicted. G3P[8] strains were dominant (84.5%), while G1P[8] and G2P[4]strains each comprised 5.1% of specimens.
