A belief seems to have become entrenched in the professional mind that infants and young children are not suitable subjects for comprehensive allergy diagnostic procedures. This group has therefore been neglected, and we have little data with respect to their allergic status.
Buffum,* in his valuable studies on asthma in the first year of life, is one of the few investigators who showed that skin tests are valuable. Kaufmann5 and Davis6 also give evidence of the need for studying asthma in the infant. Glaser and Johnstone7 actually project the idea that control of the allergic diseases should begin in the newborn period.
Infants and young children may outgrow their hypersensitivities spontaneously8 or may develop an immunologic tolerance through continued natural contact. On the other hand, allergy that appears in the very young may persist into adult life.
