Notification of Nontuberculous Mycobacteria: An Australian Perspective

Area of Science:

• Public Health
• Infectious Diseases
• Mycobacterial Infections

Background:

• Mycobacterial infections, including tuberculosis (TB) and nontuberculous mycobacteria (NTM), are notifiable in Queensland, Australia.
• Initially implemented to distinguish NTM from TB, this notification system has highlighted the rising incidence and evolving epidemiology of NTM.
• The increasing prevalence of NTM has shifted focus from a public health priority to understanding associated public and environmental health concerns.

Purpose of the Study:

• To describe the evolution of mycobacterial infection surveillance in Queensland.
• To highlight the transition from manual to digital reporting of mycobacterial laboratory isolates.
• To emphasize the importance of ongoing monitoring for emerging NTM pathogens.

Main Methods:

• Review of the notifiable disease reporting system for mycobacterial infections in Queensland.
• Transition from clinician-based reporting to digital reporting of laboratory isolates.
• Analysis of data for species and geographic distribution by health service district.

Main Results:

• Digital reporting enabled more frequent and detailed data analysis, including weekly, quarterly, and annual reports.
• Reports now provide species and geographic distributions, aiding in the identification of disease clusters.
• The system facilitates systematic reviews of different mycobacterial species and their epidemiology.

Conclusions:

• The digital reporting system enhances the ability to monitor NTM diseases and identify public health risks.
• Ecological and climate changes necessitate ongoing surveillance of evolving NTM pathogens.
• Timely reporting is crucial for understanding and managing the public health impact of NTM, especially concerning antibiotic-resistant strains like Mycobacterium abscessus.
