Summary
Directly Observed Treatment Strategy (DOTS) for tuberculosis control faces significant implementation barriers in high burden countries. Financial constraints and lack of political commitment hinder progress, impacting global TB targets.
Area of Science:
- Public Health
- Infectious Disease Control
- Global Health Security
Background:
- Tuberculosis (TB) remains a major global health challenge, particularly in high burden countries (HBCs).
- The World Health Organization (WHO) recommends Directly Observed Treatment Strategy (DOTS) short course as a cost-effective TB control measure.
- Financial limitations in many endemic countries restrict the widespread implementation of DOTS.
Purpose of the Study:
- To identify barriers to the implementation and progress of DOTS in 22 high burden countries.
- To analyze the factors contributing to the slow adoption and expansion of DOTS in these regions.
Main Methods:
- A critical review and comparison of Medline abstracts, published papers, and WHO reports.
- Analysis focused on standard parameters of TB control and DOTS implementation.
Main Results:
- Limited progress in DOTS implementation has been observed in the last decade across 22 high burden countries.
- Financial inabilities, economic recession, and socio-political turmoil significantly impede national TB control programs.
- Countries like Afghanistan, Pakistan, India, Brazil, Zimbabwe, South Africa, and Uganda face ongoing challenges with DOTS.
Conclusions:
- Increasing TB caseloads, morbidity, and mortality pose a significant threat to health systems and international security.
- Lack of political commitment and over-reliance on international aid, with minimal domestic investment, are critical issues.
- Program managers in HBCs must increase spending, demonstrate commitment to DOTS, and enhance case detection and management to meet global TB targets.
