Intracutaneous tuberculin tests were performed on 475 schoolchildren aged 9œ–15œ years in 1965, and 1,858 school-children aged 7–15 years in 1971. An induration 10 mm in diameter was taken as the criterion of a tubercular infection. It was present in 2.11% of cases in 1965 and 0.81% in 1971. These results were used to estimate the yearly infection rate for tuberculosis. It demonstrates that the actual risk of tuberculosis infection in Stuttgart is very low at 0.03%. The reduction in the infection rate of tuberculosis over the years and with increasing age was 14.9%, corresponding to the conditions reported from The Netherlands.
