Tuberculosis notifications in Australia, 2015-2018.

ABSTRACT: In 2018, the National Notifiable Diseases Surveillance System received 1,438 tuberculosis (TB) notifications, representing a rate of 5.8 per 100,000 population, consistent with the preceding three years. Australia has achieved and maintained good tuberculosis (TB) control since the mid-1980s, sustaining a low annual TB incidence rate of approximately five to six cases per 100,000 population. The number of multi-drug-resistant TB (MDR-TB) cases diagnosed in Australia is low by international standards, with approximately 2% of TB notifications per year classified as MDR-TB. Australia's overseas-born population continue to represent the majority of TB notifications (between 86% to 89% across the four reporting years) and the Aboriginal and Torres Strait Islander population continues to record TB rates around four to five times higher than the Australian-born Non-Indigenous population. Whilst Australia has achieved and maintained excellent control of TB in Australia, sustained effort is required to reduce local rates further, especially among Aboriginal and Torres Strait Islander populations, and to contribute to the achievement of the World Health Organization's goal to end the global TB epidemic by 2035.

Current thinking on the management of tuberculosis.

High-income countries are moving toward tuberculosis (TB) elimination. Sophisticated diagnostic tests and effective treatment regimens are readily available. The range of available resources even makes effective treatment of multidrug-resistant tuberculosis (MDRTB) possible. The introduction of highly active antiretroviral therapy and specific TB control measures has reduced the incidence of HIV-associated TB disease. Unfortunately, the situation in low-income countries that carry 95% of the global TB burden is less positive. TB diagnosis still relies upon sputum smear microscopy. The management of MDRTB remains problematic though guidelines for DOTS-plus programs have been developed, and cheaper second-line drugs are becoming available. The HIV epidemic continues to confound TB control efforts, particularly in sub-Saharan Africa. The appropriate package of interventions for controlling HIV/TB disease remains undefined and unimplemented. The international community must provide the funding and technical support to address the alarming dichotomy in TB control that exists between rich and poor countries.
