*Strain HC12016 is RVA/Human-wt/JPN/HC12016/2012/G1P[8] (G1-P[8]-I2-R2-C2-M2-A2-N2-T2-E2-H2). The various strains included in this table are genetically related to strain HC12016, and of the strains tested, these showed the highest sequence identity to strain HC12016 in each gene segment. Underlining indicates the highest identity to strain HC12016, excluding DS-1–like G1P[8] strains. Dark gray indicates >99% identity to strain HC12016, excluding DS-1–like G1P[8] strains. Light gray indicates >98% identity to strain HC12016, excluding DS-1–like G1P[8] strains. RVA, rotavirus A; VP, viral protein; NSP, nonstructural protein.
