Increased frequency of rotavirus G3P[8] and G12P[8] in Argentina during 2008-2009: Whole-genome characterization of emerging G12P[8] strains

The emergence of G12P[8] rotaviruses was due to the introduction of a new strain, rather than to a reassortment of the G12P[9] strains previously circulating in our country. This study assesses the temporal and geographical changes in genotypes prevalence as well as the periodic emergence of unusual G genotypes.
