Aborigines and tuberculosis: why they are at risk

Area of Science:

• Public Health
• Infectious Diseases
• Epidemiology

Background:

• Aboriginal Australians exhibit elevated incidence rates of Mycobacterium tuberculosis compared to the general population.
• Contemporary data is insufficient to fully evaluate the risk tuberculosis poses to Aboriginal communities.
• Tuberculosis presents a significant concern due to its potential interaction with human immunodeficiency virus (HIV).

Purpose of the Study:

• To determine the morbidity and mortality associated with tuberculosis in Australian Aborigines.
• To ascertain the prevalence of known tuberculosis risk factors within this population.
• To consider the public health implications arising from the study's findings.

Main Methods:

• Review of available data on tuberculosis in Australian Aborigines.
• Analysis of morbidity and mortality statistics.
• Assessment of known risk factors for tuberculosis and HIV infection.

Main Results:

• Sparse evidence indicates higher infection and clinical tuberculosis rates in Aborigines versus non-Aboriginal Australians.
• A high prevalence of known tuberculosis risk factors exists among Aborigines.
• A significant prevalence of HIV infection risk factors is also noted in this population.

Conclusions:

• Concurrent risk factors for tuberculosis and HIV in a population with high tuberculosis rates are a serious public health concern.
• Effective tuberculosis control strategies, including rapid diagnosis, treatment, and contact tracing, are crucial for Aborigines.
• Preventive therapy for infected individuals warrants consideration.
