National Rotavirus Surveillance in Argentina: high incidence of G9P[8] strains and detection of G4P[6] strains with porcine characteristics.

Group A rotaviruses are the most frequently detected viral agents associated with diarrhea in infants and children worldwide. It has been estimated that every year almost 120,000 cases of diarrhea associated with rotavirus occur in children under 5 years old in Argentina. In this work, we present the rotavirus strain diversity detected during the first 2 years of the National Surveillance Network for Diarrheas implemented by the Ministry of Health in Argentina.
