Outline
1. The new global TB targets
2. Progress so far - did we reach the MDG targets?
3. The new End TB strategy – what's new?
4. Some of the challenges – and solutions
5. Towards elimination - framework for low-incidence countries
Vision: A world free of TB Zero TB deaths, Zero TB disease, and Zero TB suffering
Goal: End the Global TB epidemic: incidence <10/100,000
Vision, goal, targets, milestones
End TB strategy – "Projected" acceleration of TB incidence decline
Optimize use of current & new tools emerging from pipeline,
pursue UHC and social protection, social determinants
-10%/year by 2025
-17%/year
Current global trend: -1.5%/year
Introduce new tools: a vaccine, new drugs and shorter regimens for
treatment of active TB and latent infection, a point-of-care test
-5%/year
And then – towards elimination
<100 cases (all forms)
per million
Low incidence
<10 cases (all forms)
per million
Pre-elimination
By 2035?
<1 case (all forms)
per million
Elimination
By 2050, or later?

"The planned interventions at the level of scale-up reached in 2015 will result in an average rate of decline in global TB incidence of 5–6% per year."

The End TB Strategy
Implementing the End TB Strategy
THE ESSENTIALS aims to guide actions
at national level to adapt, launch and
implement the World Health
Organization’s End TB Strategy.
It calls for major transformations in the
way we all work to better support
those affected and to end the
epidemic.
Launch: March 2016:
www.who.int/TB
The End TB Strategy:
3 pillars and 4 principles
Measuring progress TOP-TEN PRIORITY INDICATORS (NOT RANKED) FOR MONITORING IMPLEMENTATION
OF THE END TB STRATEGY AT GLOBAL AND NATIONAL LEVELS, WITH RECOMMENDED
TARGET LEVELS THAT APPLY TO ALL COUNTRIES
Indicator Recomm-
ended target level*
1 TB treatment coverage ≥90%
2 TB treatment success rate ≥90%
3 Percentage of TB-affected households that experience catastrophic costs due to TB 0%
4 Percentage of newly notified TB patients tested using WHO-recommended rapid tests ≥90%
5 LTBI treatment coverage (relevant risk groups) ≥90%
6 Contact investigation coverage ≥90%
7 DST coverage for TB patients 100%
8 Treatment coverage, new TB drugs ≥90%
9 Documentation of HIV status among TB patients 100%
10 Case fatality ratio (CFR) ≤5%
What's new? 1. Adaptation needed
Attention to risk groups and vulnerable groups - know your epidemic
2. Earlier detection and more accurate diagnosis
Contact investigation re-emphasized, including LTBI management Systematic screening in selected high-risk groups (with attention to over-diagnosis) Universal DST
3. More patient-centered care
Tailored patient support (especially for vulnerable groups) Manage co-morbidities
4. UHC and SDG agenda
Identify and address access barriers and health care quality deficiencies Regulatory approaches (notification, medicines, vital registration, etc) Social protection – a means as well as an outcome Prevention through addressing risk factors and social determinants
5. Research – no new tools, no ending TB
Global Action Framework
on TB research
Some challenges
…and solutions
Reaching the "missed" cases early is crucial (~3.6 million not diagnosed or reported)
Share of total missed cases
10 countries account for 75%
(2.7 million) of the estimated
“missed” cases globally
Indonesia + India:
1.2 million “missed” people
Estimated incidence Global notifications
9.6 million estimated
6 million notified
Case detection
Private sector notification in Inida
Required actions to improve early detection
Improve access – special focus on vulnerable groups
Universal health coverage – general access barriers
Improve awareness
Improve diagnostics
Engage all care providers – full notification
Contact investigation (with LTBI management of children <5), systematic screening of PLHIV and other selected risk groups

Percentage of new TB cases with MDR-TB
Highest % in the former USSR countries
India, China, Russia, Pakistan and Ukraine
have 62% of all MDR-TB cases
MDR-TB: 3% of new TB cases globally
End TB Strategy: Universal DST Universal health coverage including access to drugs, high quality patient friendly care, social protection
Special focus on vulnerable and hard-to-reach groups
MDR TB treatment outcomes
Patient support (education, social, financial, comorbidities, DOT, etc)
Delivery models (decentralisation, patient friendly)

Risk factor and risk group approach: 1. Document TB distribution, risk factors, and drivers of the epidemic
2. Minimize access barriers
3. Screening in selected high risk groups
4. Patient centred and tailored care
5. Deal with comorbidities
6. Provide social and financial support
7. Prevent by reducing population-level exposure to risk factors and
underlying social drivers
Poverty-disease trap
Poverty TB
• Undernutrition • Poor housing • HIV • NCDs and NCD risk factors (diabetes,
smoking, alcohol, etc) • Poor health care access
• High direct and indirect health care costs • Loss of employment and income • On average 50% of annual income lost!

Attention to risk groups and vulnerable groups - know your epidemic
2. Earlier detection and more accurate diagnosis
Systematic screening in selected high-risk groups (with attention to over-diagnosis) Contact investigation re-emphasized, including LTBI management Universal DST
3. More patient-centered care
Tailored patient support (especially for vulnerable groups) Manage co-morbidities
4. UHC and SDG agenda
Identify and address access barriers and health care quality deficiencies Regulatory approaches (notification, medicines, vital registration, etc) Social protection – a means as well as an outcome Prevention through addressing risk factors and social determinants
