Global Tuberculosis Report 2013 Supplement

TB incidence rates are also falling in all six WHO regions. The TB mortality rate has been reduced by 45% since 1990, and the target of a 50% reduction by 2015 is within reach. Seven of the 22 high-burden countries (HBCs) have met all of the 2015 targets for reductions in TB cases and deaths. These countries are Brazil, Cambodia, China, Cambodia, China, the Philippines, Uganda, the Republic of Tanzania, and Vietnam. A further four HBCs are on track to do so by 2015: Ethiopia, Myanmar, Ethiopia, and Myanmar. Combined, these 11 countries had 51% of the global TB burden in 2012 and 47% of the world's population. One of the most important indicators of global progress is an 87% treatment success rate in 2011, up from 69% in 2000. This huge improvement in the provision of high-quality TB care in most countries is a significant step towards achieving the MDG target. However, there are still challenges to be addressed. Only 5.7 million (66%, range 64-69%) of the estimated 8.6 million incident cases of TB in 2012 were both detected and notified to national TB programs or national surveillance systems. This leaves a gap of about 3 million people with TB who were "missed", either because they were not diagnosed or because they were diagnosed but not reported. There are 11 countries that are not on track to reach one or more of the three targets for reductions in incidence, prevalence, and mortality. The 11 countries that are not on track to reach the targets are the Democratic Republic of the Congo, Mozambique, Nigeria, South Africa, and South Africa in the African Region; Bangladesh and Pakistan in the South-East Asia Region; and the Russian Federation in the European Region. In two of the 22 HBCs (Mozambique and South Africa), the incidence rate is still estimated to be rising. The global TB mortality rate has been reduced by 45% since 1990, and the target of a 50% reduction by 2015 is within reach. The TB incidence rate has been falling for about a decade, and TB incidence rates are also falling in all six WHO regions. The 11 countries that are not on track to reach the targets are the Democratic Republic of the Congo, Mozambique, Nigeria, South Africa, and South Africa in the African Region; Bangladesh and Pakistan in the South-East Asia Region; and the Russian Federation in the European Region.
