[Optimal measures for early detection and prevention of tuberculosis in adolescents].

Data are given on the examination of 23,507 schoolchildren, students of specialized secondary and technical vocational schools covering 13 regions of the country. It has been found that tuberculosis contamination of adolescents is 30-33%, on average, but it varies considerably depending on the general epidemiologic situation at the place of residence, and the social status of adolescents. As compared to schoolchildren, tuberculosis contamination and the frequency of tuberculin reaction reversion are higher in students of technical vocational schools. The importance of BCG vaccination in adolescents, as the main method for tuberculosis is prevention, is substantiated. About 30% of adolescents, on average, are subject to revaccination. It is concluded that children and adolescents should be revaccinated twice: at 6-7 years (1st form) and 14-15 years (8-9th form).
