Management of Tuberculosis Infection: Current Situation, Recent Developments and Operational Challenges

Area of Science:

• Infectious Diseases
• Immunology
• Public Health

Background:

• Tuberculosis infection (TBI) represents a dynamic host-bacilli interaction, with 2 billion globally infected.
• 5-10% of infected individuals develop active TB disease, a risk amplified by factors like HIV co-infection.
• The End-TB strategy emphasizes programmatic TBI management to meet global elimination targets.

Purpose of the Study:

• To review the current landscape of tuberculosis infection management.
• To highlight recent advancements in TBI diagnostics and preventive therapies.
• To discuss operational challenges in TBI programmatic management.

Main Methods:

• Literature review of current TBI management strategies.
• Analysis of recent developments in diagnostic tools for differentiating TBI from active TB.
• Examination of novel short-course preventive treatment regimens.

Main Results:

• Significant global burden of TBI necessitates effective management strategies.
• Emerging diagnostic tests offer improved discrimination between latent infection and active disease.
• Short-course preventive treatments show promise in reducing TB progression.

Conclusions:

• Effective management of TBI is critical for achieving global TB elimination goals.
• Advancements in diagnostics and treatment are pivotal for controlling the TB epidemic.
• Addressing operational challenges is essential for successful TBI programmatic implementation.
