National tuberculosis (TB) prevalence surveys provide a nationally representative measurement of the burden of TB disease in the population, at a given point in time. Repeat surveys allow assessment of trends and tracking of progress towards national and global targets for reductions in TB disease b...urden. Survey data also provide important insights that can help national TB programmes to identify ways to improve TB diagnosis and treatment.
National TB prevalence surveys are relevant in countries that do not yet have national disease notification and vital registration systems that are of sufficiently high quality and coverage to allow reliable tracking of TB disease burden.
