Burden of rotavirus-associated and non-rotavirus-associated diarrhea among nonhospitalized individuals in central Italy: a 1-year sentinel-based epidemiological and virological surveillance.

A community sentinel pediatrician-based epidemiological and virological surveillance study was conducted to estimate the incidence of gastroenteritis and laboratory-confirmed rotavirus-associated disease. The 1-year cumulative incidence of gastroenteritis in the cohort of children aged 0-5 years was 21%, with the highest rates in the 7-12-month and 13-18-month age groups (41.1% and 41.

Molecular characterization of a new variant of rotavirus P[8]G9 predominant in a sentinel-based survey in central Italy.

Rotavirus P[8]G9 was recognized as the most widespread genotype during a sentinel-based survey in Italy; phylogenetic analysis of the VP7 and VP4 genes showed that Italian isolates constituted a closely related genetic cluster distinct from the other G9 strains recently isolated in other European countries, America, and Asia.
