Respiratory Syncityal Virus A and B: three bronchiolitis seasons in a third level hospital in Italy.

ABSTRACT:

Background

Respiratory syncytial virus (RSV) is the main cause of hospitalization for bronchiolitis among infants. RSV is classified into two subtypes, A and B, whose predominance alternates during different epidemic seasons. The clinical impact of viral factors is controversial and many evidences suggest a critical role for the immune host response. Premature children are at the highest risk for severe RSV infection. The main aim of this study is to identify the different RSV subtypes circulating in the last three epidemic seasons and to evaluate whether any of them was associated with poor prognosis in term and preterm infants.

Methods

We performed a retrospective analysis of medical records for all patients aged less than one year which were hospitalized during the winter
