Global TB control targets

2015:50% reduction in TB prevalence and deaths by 2015

2015:Goal 6: Combat HIV/AIDS, malaria and other diseases

Target 8: to have halted by 2015 and begun to reverse the incidence…

Indicator 23: prevalence and deaths associated with TB

Indicator 24: proportion of TB cases detected

and cured under DOTS

2005:World Health Assembly:

- To detect at least 70% of infectious TB cases

- To treat successfully at least 85% of detected cases

Plan to Stop TB in EEUR: achievements

  • STOP TB strategy:

  • DOTS

  • MDR-TB, TB/HIV, prisons

  • Health system

  • All providers

  • ACSM, people, patients

  • Research

Outcomes among new, definite pulmonary TB cases, EU & other regions, 2003*

Despite low mortality rates, the proportion of TB patients notified in the EU who die while on treatment is substantial, even when compared to other regions in the world. This is one limitation keeping many EU countries from achieving the WHO target of 85% success among previously untreated pulmonary TB cases.

* Mean for 19 EU countries (EuroTB); data from other regions refer to DOTS cohorts (WHO Global Tuberculosis Control: Surveillance,

Why the new Stop TB Strategy ?

Vision, Goals, Objectives

Vision:A WORLD FREE OF TB

Goal:To dramatically reduce the global burden of TB by 2015 in line with the MDGs and the Stop TB Partnership targets

Objectives:

  • Achieve universal access to high-quality diagnosis and patient-centred treatment

  • Reduce the human suffering and socio-economic burden associated with TB

  • Protect poor and vulnerable populations from TB, TB/HIV and multidrug-resistant TB

  • Support development of new tools and enable their timely and effective use


Plan to stop tb in eeur planned milestones

Plan to Stop TB in EEUR: Planned milestones


The burden of tb in 2006

What are the main challenges ?

  • DOTS not yet fully expanded and of high quality everywhere

  • TB/HIV, especially in Africa, and MDR-TB, especially in former USSR and China

  • Weak health systems and services impeding proper TB control and care

  • Not all practitioners engaged

  • Communities un-aware and un-involved

  • Research not producing yet new tools and outside of the interest of TB "controllers"


Western and central europe

Western and Central Europe

  • Today, mainly sexual transmission in Western and Central Europe

  • Exceptions: significant IDU epidemics in ESP, POR, ITA, SWI, POL

  • 25-65% of all cases are among MSM

  • Up to 75% of all heterosexual cases are among immigrants from high prevalence countries and women are >50% of all heterosexual cases

  • Vulnerable Groups: MSM & immigrants, specially immigrant women


Eastern europe

Eastern Europe

  • Mainly IDU related transmission in Eastern Europe

  • 68-85% of all cases are male

  • Up to 30% of infected females are IDU and 50% are partners of IDU

  • 30-50% of all HIV infections are among those under 25 years

  • Vulnerable Groups: IDU, sex workers, prisoners, ethnic minorities, migrants

European framework for tb hiv interim policy on collaborative tb hiv activities

European Framework for TB/HIVInterim policy on collaborative TB/HIV activities

  • Establish the mechanism for collaboration

    • Set up a coordinating body for TB/HIV

    • Conduct surveillance of HIV prevalence among TB patients

    • Joint TB/HIV planning

    • Conduct monitoring and evaluation

  • Decrease the burden of TB in people living with HIV/AIDS

    • Intensified TB case finding

    • Introduce INH preventive therapy

    • Ensure TB infection control in health care and congregate settings

  • Decrease the burden of HIV in TB patients

    • Provide HIV testing and counselling

    • Introduce HIV prevention methods

    • Introduce co-trimoxazole preventive therapy

    • Ensure HIV/AIDS care and support

    • ART


The burden of tb in 2006

  • Cat 1: national adult HIV prevalence >1% or HIV prevalence in TB pts >5%: all activities recommended in the Interim policy to be considered for implementation

  • Cat 2: national adult HIV prevalence below 1% and administrative areas with adult HIV prevalence >1% - combination of Cat 1 and Cat.3

  • Cat 3: national adult HIV prevalence below 1% and no administrative areas with adult HIV prevalence >1%:

    • Conduct surveillance of HIV prevalence among TB patients

    • Decrease the burden of TB in people living with HIV/AIDSwith focus on groups at high risk for TB and HIV – IDUs, MSM, sex workers, those living in congregate settings)
