[Epidemiology of pulmonary tuberculosis in the prison environment].

Despite the decline in pulmonary tuberculosis in industrial countries since the beginning of the century, screening remains important, particularly in population groups at special risk such as jail inmates. A 1-year prospective study in 865 prisoners in Geneva shows that the prevalence of active and residual tuberculosis is five to ten times higher than in the general population. The reasons for this high prevalence are low socio-economic status and lack of a regular job or fixed residence for many prisoners. These facts illustrate the importance of introducing systematic diagnosis and, if necessary, rapid therapeutic measures in jails, with the triple purpose of contributing to the fight against tuberculosis among prisoners, prison staff and the population as a whole.
