The results of this study show that, during the respiratory syncytial virus (RSV) season, RSV and all-cause bronchiolitis (ACB) were a leading cause of hospitalizations and ED visits among US infants under 1 year of age. Current policy does not support routine RSV testing of clinical lower respiratory tract infections (LRTIs) among infants. In that context, as an approximation of RSV LRTI visits in each setting, ACB can be considered an upper bound and RSV can be considered a lower bound of the true proportion of hospital encounters associated with RSV in these settings.
