Respiratory Syncytial Virus Genotypes and Disease Severity in Young Children Hospitalized with Bronchiolitis

Background: There is limited data on how different RSV genotypes and associated viral loads influence disease phenotypes. We characterized the genetic variability of RSV strains during five non-consecutive respiratory seasons, and evaluated the role of RSV subtypes, genotypes and viral loads on clinical disease severity.
