High Burden Countries (HBC) 22 countries account for 80% of the world’s burden of TB
Data source: WHO Global TB Report 2011 40% of all TB cases
Global Burden of TB and TB/HIV, 2010 *Including deaths among people living with HIV Data from WHO Global TB Report, 2011 Estimated number of cases Estimated number of deaths All forms of TB 8.8 million 1.4 million* All forms of TB, women only 3.2 million 320,000 HIV-Associated TB 1.1 million 350,000 Multidrug-resistant TB (MDR-TB) 650,000 ~150,000 (2008)

HIV testing of TB patients is now standard practice in many countries, especially in Africa. In 2010, 34% of notified TB patients knew their status.
Global coverage of ART for TB/HIV patients remains low at 46%, despite a large increase in HIV testing of TB patients
In 2010 2.3 M PLHIV screened for TB (58% of PLHIV) 178,000 PLHIV enrolled on IPT (12% of newly enrolled PLHIV)
Global Plan to Stop TB 2011-2015 Summary of main TB/HIV indicators Data from WHO Global TB Report, 2011 TB/HIV indicators Baseline (2009) 2010 % TB patients tested for HIV 26% 34% % HIV+ TB patients treated with CPT 75% 77% % of HIV+ TB patients treated with ART 37% 46% % of PLHA attending HIV care services who were screened for TB at their last visit ~25% 58% % of PLHA attending HIV care services who were enrolled on IPT; among those eligible <1% 12%
2012 anticipated: $0.6 billion, 50% higher than 2006 at $0.4 billion.
Far short of funding provided to Malaria and HIV/AIDS in 2010:
Malaria $1.8 billion, HIV/AIDS $6.9 billion
Treatment: With the threat of MDR and XDR-TB, there are less drugs available, they are much more expensive, have worse side effects and treatment is 4 times longer – 2 years instead of 6 months.
TB R&D: “The field of research on TB has really missed generations of advances in biology and technology. We really need to bring TB research from the 19th into the 21st century,” -Anthony S. Fauci, director of the NIAID at the release of the WHO Global TB Report 2011.
