title: Etiologic factors in infantile asthma.
abstract: In a group of 83 infants with asthma the major etiologic factors were found to be foods, environmental inhalants and respiratory infections. Airborne pollens and molds were found to be important in a small number of patients during the latter part of infancy. IgA deficiency and general anesthesia under the age of two years played a less well defined role in the pathogenesis of infantile asthma.
