Value of a risk scoring tool to predict respiratory syncytial virus disease severity and need for hospitalization in term infants.

Several environmental and demographic risk factors have been validated and are used to determine the risk of acquiring severe respiratory syncytial virus (RSV) infection and subsequent hospitalization in late preterm infants born at 33-35 weeks gestational age. The applicability of the same composite model of risk factors in the term population has not been fully explored. The primary objective of this pilot study was to establish whether a risk scoring tool (RST), could predict the severity of RSV infection in term, RSV-positive infants who were hospitalized.
