title: Allergy and infection.
abstract: The majority of infectious asthma in children is of viral etiology. The respiratory syncytial and parainfluenza viruses are the etiologic agents in most young children, whereas rhinovirus primarily initiates asthmatic episodes in older children. Short-term or alternate day maintenance corticosteroid therapy probably does not significantly increase the asthmatic child's susceptibility to infection.
