  1. Focusing tuberculosis contact tracing by smear grading of index cases.

    Article - En anglais

    Several studies have confirmed that the contacts of sputum-smear-positive patients are a high risk group.

    We made a prospective survey to investigate the contacts of infectious cases of pulmonary tuberculosis in order to evaluate whether different grades of sputum-smear positivity have any consequence in the emergence of new cases.

    The number of contacts reported by 134 index cases was 609.

    These included 136 (22%) who had been in close contact to the index case, 69 of them to patients heavily positive by sputum smear.

    Tracing of 609 contacts over 2 yr revealed four (0.7%) new cases of active tuberculosis.

    All of them were close contacts, and, moreover, all four (5.8%) belonged to the group of 69 whose index case had a heavily positive sputum smear.
