Current respiratory syncytial virus prevention strategies in high-risk infants.
Respiratory syncytial virus (RSV) was initially isolated in 1956. Since then it has become recognized as a major pathogen worldwide. It is a ubiquitous pathogen that produces seasonal epidemics. Primary infection occurs in children before 2 years of age. In older children and adults, RSV usually manifests itself as an upper respiratory tract infection. In immunecompromised patients, those with underlying cardiopulmonary disorders, premature infants, and other vulnerable individuals, RSV infection can produce severe bronchiolitis or pneumonia. In recent years we have observed exciting new information about the prevention of serious RSV infection in high-risk infants including infection control practices, active immunity and passive immunity. Two immunoprophylaxis products (RSV i.v. immune globulin and palivzumab) have been developed for clinical use in the prevention of serious RSV infection. Many other agents including vaccines, super monoclonal antibodies, and antivirals are under development. Although clinicians now have the ability to provide their most vulnerable patients with meaningful prevention strategies, much more needs to be done before we can regard RSV as a preventable disease.
