[BCG vaccination and/or tuberculin testing for the elimination of tuberculosis (author's transl)].

In an epidemiological an clinical pilote study the authors have done a tuberculin testing survey in combination with the mass X-ray examinations in 2553 adults in the village Dabas with 3885 inhabitants. The percentage of tuberculin positive persons of the various age groups refers to a still high infection prevalence of the adults. However, among the persons under 30 and older than 60 years a high percentage of tuberculin negative ones was found (27-38%). By reason of their investigations the increasing significance was emphasized. The authors recommend, to revise once more the practice of BCG vaccination of the persons under 30 years, a more intensive dispensaric care of the adolescent living in an infectious environment, in collectives and of all the old tuberculin-negative persons.
