 AB    OBJECTIVE: To investigate a possible outbreak of Mycobacterium
       tuberculosis infection in a HIV outpatient treatment facility. METHODS:
       Following the diagnosis of active pulmonary tuberculosis in a
       HIV-infected patient receiving outpatient intravenous therapy for CMV
       pneumonitis, 94 patients potentially exposed in the treatment room were
       followed up with 3 monthly screening chest radiographs and where
       possible, sputum examination. RESULTS: Through the initial screening
       undertaken no patients who were potentially exposed had radiological
       evidence of active pulmonary tuberculosis. Amongst those patients who
       also had sputum examinations, none were positive on microscopy or
       culture for M. tuberculosis. However, 3 of these patients developed
       active pulmonary tuberculosis between 8 and 10 weeks following the
       diagnosis of the index case. No further cases amongst the potentially
       exposed cohort of patients has been diagnosed after 12 months. M.
       tuberculosis isolates from the index case and the three other cases were
       found to be identical strains by DNA typing. CONCLUSION: Despite low
       prevalence of M. tuberculosis infection amongst HIV-infected patients in
       Australia, there is a clear risk of transmission in hospital settings.
       Considering there are a wide range of potential pulmonary pathogens and
       respiratory disease processes in HIV-infected patients, vigilance is
       required to detect M. tuberculosis cases at the earliest possible time.
