Current developments and future perspectives for TB diagnostics

Area of Science:

• Infectious Diseases
• Global Health
• Medical Diagnostics

Background:

• Tuberculosis (TB) is a persistent global epidemic with significant morbidity and mortality, disproportionately affecting low-income countries.
• The World Health Organization (WHO) has declared TB a global emergency, highlighting its severe impact.
• Co-infections with HIV and the rise of drug-resistant TB strains present substantial challenges to disease control.

Purpose of the Study:

• To review current advancements in diagnostic tools for tuberculosis.
• To identify unmet needs and future directions in TB diagnostics.
• To discuss the potential for improved TB detection, particularly in specific populations and for predicting disease progression.

Main Methods:

• Literature review of recent developments in TB diagnostics.
• Analysis of current diagnostic capabilities and limitations.
• Exploration of emerging technologies and research trends in the field.

Main Results:

• Significant progress has been made in TB diagnostics over the past decade.
• Key needs remain, including point-of-care tests, improved diagnostics for immunocompromised individuals and children, and methods to predict latent TB progression.
• The review synthesizes current diagnostic strategies and future prospects.

Conclusions:

• Continued innovation in TB diagnostics is essential for global TB control.
• Addressing diagnostic gaps in vulnerable populations and for latent infection is critical.
• Future developments aim to provide more accessible, accurate, and predictive TB diagnostic solutions.
