Multicenter Study of Viral Etiology and Relapse in Hospitalized Children With Bronchiolitis Kohei Hasegawa, MD, MPH,* Jonathan M. Mansbach, MD, MPH,† Stephen J. Teach, MD, MPH,‡ Erin S.

Camargo, Jr., MD, DrPH* Background: It is unclear whether the infectious etiology of severe bronchiolitis affects short-term outcomes, such as posthospitalization 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. Methods: We performed a 16-center, prospective cohort study of hospitalized children age
