TL;DR: In conclusion, genetic interaction by reassortment among cocirculating rotaviruses is not a rare event and contributes significantly to their overall diversity.

TL;DR: The ability of the network to identify strains circulating with an incidence of ⩾1% allowed the identification of possible emerging strains such as G8 and G12 since the beginning of the study; analysis of recent data indicates their increased incidence.

TL;DR: The consecutive emergence of new GII.4 variants is highly indicative of immune-driven selection, and their predominance in health care settings suggests properties that facilitate transmission in settings with a high concentration of people such as higher virus loads in excreta or a higher incidence of vomiting.

TL;DR: Early infection and frequent reinfection in a locale with high viral diversity resulted in lower protection than has been reported elsewhere, providing a possible explanation why rotavirus vaccines have had lower-than-expected efficacy in Asia and Africa.

TL;DR: A degenerate version of the rotavirus P[8]-specific primer (1T-1) allowed strains previously untypeable due to the accumulation of point mutations at the primer binding site to be P typed by reverse transcription-PCR.
