Tuberculosis. The old and the new.
BACKGROUND
The overall incidence of tuberculosis (TB) in the general Australian population is low and has been stable over the past 10 years. The incidence is, however, much higher in certain subgroups of the population and these include overseas-born people (especially from countries in Asia) and Aboriginal and Torres Strait Islander populations. Other groups regarded as at increased risk of TB are nursing home residents, the homeless, prison populations and immunosuppressed patients, especially those who are HIV positive.


OBJECTIVE
Patients regarded as high risk should be investigated promptly if they present with signs or symptoms suggestive of TB.


CONCLUSIONS
The best method of preventing the transmission of TB and preventing the emergence of drug resistant strains of the organism are by ensuring that sputum smear positive patients are isolated till non-infectious; that any patient with TB receives prompt and adequate treatment; that all patients with TB comply with a full course of treatment till cured: and that contact tracing is undertaken to detect newly infected patients so as to offer chemoprophylaxis and to detect previously unrecognised cases.
