[Tuberculosis control programme in Tunisia: efficacy assessment].

The aim of this study was to assess the efficacy of the national Tuberculosis Control Programme in Tunisia, by applying the 8-stage model proposed by Piot (1967). Two retrospective cohorts of tuberculosis cases, including all new smear-positive cases detected by all laboratories in the study area during the study period, were selected at least 2 years after treatment began. The real number of new active cases during the study period was estimated at 142, the case detection rate at 61%.
