Simultaneous viral infection and childhood bronchiolitis obliterans.

Lower respiratory tract infections by respiratory syncytial virus (RSV) are frequent in childhood. Association of RSV with bronchiolitis obliterans has rarely been established. We report a 13-month-old child with bronchiolitis obliterans following co-infection by RSV and adenovirus, and suggest that complicated evolution of an acute bronchiolitis case can indicate an association of pathogens.
