SAARC Regional Strategy for Control / Elimination of Tuberculosis
SAARC has adopted WHO’s Global Stop TB Partnership strategy which envisions a TB-free world and elimination of TB by 2050.
Guiding Principles & SAARC TB Control Strategy
The strategic directions for TB Control are grounded in six principles, which will guide achievements of the strategic goals as follows:
Inclusiveness
Working in partnership with all stakeholders will be at the core of the TB Control Strategies in the SAARC Region. The stakeholders would include governments, private sector, non-governmental organization and civil society, researchers, academia, policymakers, professional bodies, national and international development agencies.
Equitable access to effective interventions
The TB Control strategy would endeavor to ensure equity in access, availability and utilization of the quality TB Control services for all sections of the population including poor and marginalized, special populations such tribal, people living in slums, and distant and inaccessible rural areas and terrains.
Flexibility
All the SAARC Member States have their National Tuberculosis Programs and follow a general framework of DOTS and STOP TB partnership. However, each country may have specific and peculiar circumstances that would require adaptation of broad strategies to their own.
Quality
Commitment to high quality DOTS that would provide diagnostic services and treatment with effective anti-tubercular drugs will be an integral part of the strategy.
High Impact Interventions
High priority to research and innovation that have the greatest potential to improve and enhance performance and impact in reducing inequities, high cure rates, and contribute to achieving the Millennium Development Goals (MDGs) in the Region.
Ethics and Human Rights
Strategy would be based on the core values of equity, fairness and integrity, and promoting the utilization of scientific evidence and respect for gender and human rights.
Targets for SAARC Region
SAARC Region Targets for the scale-up of interventions for TB care and control set in line with the Global Plan to Stop TB 2011–2015.
- By 2015: Reduce prevalence and death rates by 50%, compared with their levels in 1990.
- By 2050: Reduce the global incidence of active TB cases to <1 case per 1 million population per year
BURDEN OF TUBERCULOSIS IN SAARC REGION
SAARC Epidemiology
The SAARC region, with an estimated annual incidence of 3.7 million TB cases equivalent to 203 cases per 100 000, accounted for 37% of the global burden of TB incidence in the year 2019. Three of eight Member States in the SAARC Region are High TB and High MDR-TB burden countries among 30 High burden countries. India accounted for 26%, Pakistan 5.7% and Bangladesh 3.6% of the world’s TB Cases. An estimated 0.5 million (30 cases per 100 000) TB deaths occurred in the region in 2019.
