Respiratory syncytial virus causes worldwide epidemics of respiratory disease. Of 23 children infected with respiratory syncytial virus, 65% had low serum concentrations of vitamin A during acute illness; these low values were associated with more severe illness. Vitamin A supplementation may have a role in the management of infection with respiratory syncytial virus.
