Abstract

When the physicians.who are middle aged today studied medicine, they were taught that tuberculous infection was so widespread that every one who reached childhood had already been infected. Nowadays medical students are taught something quite different; that hardly 50 per cent of all children have a positive reaction to tuberculin and that it is not until after the age of puberty that the majority of persons gradually become infected. This difference in doctrine does not imply that the former conception was wrong. A change in the age at which primary infection occurs has undoubtedly taken place. This can be proved for certain by comparing the results of tuberculin tests done by the same method and on children of the same social groups at intervals of two or three decades. The results of two comparable investigations conducted at the Children's Clinic in Vienna are often cited. Some thirty years ago (1909)
