[The risk of tuberculosis in students of professional schools].
In four technical schools in a Burcharest district, the first grade scholars were tested at the beginning of the term with 2 units PPD; those with a reaction of 0--9 mm received BCG vaccine. After 6 months, in the 3rd term, they were controlled by MMR examination which was repeated in the second year. The incidence of tuberculosis detected by X-ray and clinically was of 298.8 per 100 000 in the frist year and 283.6 per 100000 in the second year. In all disease cases but one the intradermoreation and greater than or equal to 15 mm which may thus be considered the risk group (a risk of 9.5 per thousand); there were no cases among the children revaccinated with BCG. In conclusion it is recommended to apply in adolescent communities tuberculin testing and BCG revaccination of the non-infected children 0--9 mm) in their first term and periodical X-ray control of the risk group, i.e. those with a reaction of 15 mm or more.
