Catastrophic costs potentially averted by tuberculosis control in India and South Africa: a modelling study.

Background: The economic burden on households affected by tuberculosis through costs to patients can be catastrophic. WHO's End TB Strategy recognises and aims to eliminate these potentially devastating economic effects. We assessed whether aggressive expansion of tuberculosis services might reduce catastrophic costs.

Health-system strengthening and tuberculosis control.

Weak health systems are hindering global efforts for tuberculosis care and control, but little evidence is available on effective interventions to address system bottlenecks. This report examines published evidence, programme reviews, and case studies to identify innovations in system design and tuberculosis control to resolve these bottlenecks. We outline system bottlenecks in relation to governance, financing, supply chain management, human resources, health-information systems, and service delivery; and adverse effects from rapid introduction of suboptimum system designs.

The global tuberculosis situation. Progress and problems in the 20th century, prospects for the 21st century.

Mycobacterium tuberculosis has been identified in prehistoric remains of humans. Despite references to TB by Hippocrates and Galen, humankind had limited understanding of and few tools to defend itself against TB until the later 19th century. Subsequently, landmark advances in the 20th century provided the means to control and prevent this disease.
