[Longitudinal follow-up of contact subjects of cases of tuberculosis in Paris].

Aim: To our knowledge, the proportion of active tuberculosis diagnosed after 12-18 months during a screening tuberculosis process in a specialized centre (centre de lutte antituberculeuse [CLAT]) has not been described in France. The majority of other countries do not have any recommendation to screen at this time.

Methods: We evaluated the number of treated or not treated latent tuberculosis infections (LTI) identified during tuberculosis screening.
