Previously, only a few outbreaks of group C or E
rotaviruses were reported in the United States or United
Kingdom (Chasey and Davies 1984; Kim et al. 1999),
but recent data suggest group C rotaviruses are becoming
dominant in suckling diarrheic pigs under 7 days
of age (Rossow et al. 2010). In Brazil, genetically diverse
porcine group C rotaviruses in diarrheic and normal
fecal samples were reported in 2010 (Médici et al.
2010).
