Theme Health
Code PH-CD-1.1
MDG code MDG-6.9.1
Sub-theme Communicable Diseases (TB)
Name TB Prevalence (est. TB cases per 100,000 population) (MDG 6.9.1)
Definition Estimated number of TB cases (all forms) per 100,000 population
Calculation/Formula Estimates of TB prevalence are based on a consultative and analytical process led by WHO. National TB programmes provide surveillance data to WHO to calculate.
Assumptions Countries do not report on impact level data (TB mortality, prevalence and incidence). WHO only report on impact level (by estimates based on complex methodology documented in their report). Countries provide programmatic and surveillance data to WHO, who then apply calculations. Therefore the 2011 Global Tuberculosis report is the authoritative source on impact level indicators for TB in the region.
Limitations Direct measures of tuberculosis prevalence, which come from vital registration, are uncommon. Reliable figures require that death registration be nearly universal and that the cause of death be reported routinely on the death records and determined by a qualified observer according to the International Classification of Diseases. Such information is generally not available
Purpose/Rationale To reduce TB related morbidity, achieve Stop TB Partnership targets and contribute towards the achievement of the Millennium Development Goals. Internationally recommended impact indicator, with international and regional targets; International target is to reduce the prevalence of TB by half by 2015 relative to the levels in 1990 (contributing to the achievement of the Millennium Development Goals); Regional target is to halve the prevalence of TB by 2010 relative to the levels in 2000 (contributing to the achievement of the Millennium Development Goals).
