Rotavirus vaccination as a public health strategy to reduce the burden of hospitalization: The field experience of Italy (2008-2018).

Rotavirus (RV) infection is a leading cause of severe diarrhea among children younger than 5 years old and a considerable cause of RV gastroenteritis (RVGE) hospitalization. This study aimed to evaluate the impact of vaccination in Italy in the reduction of the burden of RV-related disease, estimating the relation between vaccination coverage and hospitalization rates. RVGE-related hospitalizations that occurred in Italy from 2008 to 2018 among children aged 0-35 months were assessed by consulting the Hospital Discharge Record database and including records whose ICD-9-CM diagnosis code was 008.
