[Distribution of Rotavirus G Genotypes during 10 years in children with acute diarrhea of the city of La Rioja, Argentina. Implications for vaccination]

Vaccination against rotavirus in Argentina is obligatory from January 2015. From 418 stools in children with acute diarrhea were collected from 2000 to 2010 in city of La Rioja, Argentina, Rotavirus was detected. The 90 rotavirus positive stools samples (21.53%) were amplified by RT-PCR and genotyped by PCR-Mix for G1, G2, G3, G4, G9 and G8. The results show that during 2000-2003, the most frequent genotype was G1 and but since 2008, the G2, G3 and G9 genotypes in single and mixed infections were detected.
