Fatal respiratory syncytial virus pneumonitis in a previously healthy child

Respiratory syncytial virus (RSV) is a cause of significant morbidity and mortality in infants and children with an immunocompromised status or a congenital heart disease. The following case describes a 6 8/12-year-old, previously normal child who had a fatal interstitial pneumonitis caused by RSV. Documentation of RSV as the etiologic agent and documentation of her immune status are presented. In light of recent advances in the rapid diagnosis and treatment of RSV, this virus should be considered in children with an unusual interstitial pneumonitis regardless of their known immunologic status.
