Sensitivity to the Cockroach in Three Groups of Allergic Children

There is a definite tendency for allergic children exposed to cockroaches to develop positive skin tests. Suburban children, who were not exposed but had the same allergic problems of wheezing and nasal symptoms, had no positive tests. There is a suggestion that this sensitivity may play a role in perpetuating allergic symptoms in some children. The cockroach seems to be an important potential allergen in susceptible populations.
