Australian Rotavirus Surveillance Program: Annual Report, 2016.

This report from the Australian Rotavirus Surveillance Program (ARSP) and collaborating laboratories Australia-wide, describes the rotavirus genotypes identified in children and adults with acute gastroenteritis during the period 1 January to 31 December 2016. During this period, 949 faecal specimens were referred for rotavirus G and P genotype analysis, of which 230 were confirmed as positive for wildtype rotavirus, and 184 were identified as rotavirus vaccine-like. Genotype analysis of the 230 samples from both children and adults revealed that G2P[4] was the dominant genotype in this reporting period nationally, identified in 29% of samples, followed by equine-like G3P[8] and G12P[8] (19% and 15% respectively). Genotype distribution remained distinct between States using RotaTeqŽ and RotarixŽ vaccines. In RotaTeqŽ States, G12P[8] strains were more common, while G2P[4] and equine-like G3P[8] genotypes were more common in RotarixŽ States and Territories. This report highlights the continued dominance of G12P[8] strains in RotaTeqŽ States and co-dominance of G2P[4] and equine-like G3P[8] in States and Territories using RotarixŽ.
