title: [Tuberculin screening in a secondary school in Montreal following a case of pulmonary tuberculosis].
abstract: We planned a tuberculin testing in a secondary school, following student exposure to a fellow student suffering from pulmonary tuberculosis. A first group of 71 students for whom exposure seemed greater, had an intradermal Mantoux test. Of these 71 students, 18 (25.3%) had a > or = 5 mm reactions; 52 went through a second test three months later, six of whom had a > or = 5 mm reaction. In light of the results of the screening in this first group, the tuberculin testing was offered to a second group of 108 students. In this second group, the result of the skin test was > or = 5 mm for 10 (9.3%) students. Out of 179 students, 34 (19.0%) had a significative reaction. A > or = 5 mm reaction was significantly associated with being male, being born outside of Québec and being a member of the first group screened.
