Many developed countries are faced with the problem of reorganizing their @entity378 -control programme to bring it into line with modern conditions. The study reported was undertaken to provide guidelines for this reorganization. It was begun in the district of Kol  n, Czechoslovakia, with a population of some 100 000, in 1961 and is still in progress. The paper covers the first 4 years of the study.In 1961 a thorough check-up was made on all @entity1 registered as having active or inactive @entity378 , or @entity358 . In 1961 and 1963 a mass X-ray and tuberculin-testing campaign, with 95% coverage, was carried out for all @entity1 over 14 years of age. All @entity1 with active @entity378 received adequate treatment. @entity1 registered as having @entity378 or suspected @entity378 were subjected to regular photofluorographic and bacteriological investigations. Newborn @entity1 were given BCG vaccination, and @entity1 aged 14 years and 19 years with negative tuberculin reactions were vaccinated.The prevalence of bacillary @entity378 fell from 150 cases in 1960 to 91 in 1964, mainly owing to a decrease in the number of chronic cases. The incidence of bacillary @entity378 detectable by direct smear microscopy, however, remained at about 25 cases throughout the period 1961-64. The risk of developing @entity378 was found to be highest in @entity1 with @entity358 or inactive @entity378 , and in @entity1 above 45 years of age and @entity1 above 65 with previously normal photofluorograms.It is concluded from the study that in developed countries priority should be given to adequate treatment of all @entity1 with active @entity378 , and to early diagnosis in @entity1 consulting physicians and in the high-risk population groups.
