Abstract
Rhinoviruses were isolated from nasopharyngeal secretions of 49 children hospitalized because of severe respiratory tract infection. The isolates were typed using 90 type‐specific antisera. No obvious relation between certain serotypes and the severity of illness was found.
Serum samples were drawn from all children simultaneously with the nasopharyngeal secretions and screened for the presence of type‐specific neutralizing antibodies. Children aged 1 week t o 6 months had higher neutralizing antibody titers and revealed a lower degree of morbidity than older children. The decline of neutralizing serum antibodies with increasing age was correlated with a higher incidence of severe disease in those aged 7‐12 months. Nevertheless, also in this age group children with mild clinical courses of disease were observed despite a low concentration or an absence of neutralizing serum antibodies. This indicates that not only neutralizing serum antibodies, but other factors also influence the clinical expression of RHV‐induced disease.
