Multicenter Study of Viral Etiology and Relapse in Hospitalized Children with Bronchiolitis

摘要

BackgroundIt is unclear whether the infectious etiology of severe bronchiolitis affects short-term outcomes, such as post-hospitalization relapse. We tested the hypothesis that children hospitalized with rhinovirus (RV) bronchiolitis, either as a sole pathogen or in combination with respiratory syncytial virus (RSV), are at increased risk of relapse.
