Respiratory syncytial virus (RSV) is one of the most important pathogens of infectious respiratory tract illness of children. An outbreak of infection with RSV regularly occurs in winter yearly, and is accompanied by an increased incidence of infants with severe lower respiratory tract illness, such as pneumonia or bronchiolitis. It has also been reported that RSV was isolated from middle ear exudate of children with otitis media. Although the pathogenesis of diseases induced by this virus is not fully elucidated, recent observations suggest an involvement of some immune mechanisms, particularly in the development of such a wheezy respiratory tract illness as bronchiolitis.
