Outcomes among new, definite pulmonary TB cases, EU & other regions, 2003* * Mean for 19 EU countries (EuroTB); data from other regions refer to DOTS cohorts (WHO Global Tuberculosis Control: Surveillance, Planning, Financing. 2006) 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.

Vision: A WORLD FREE OF TB Goal: T o 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 Why the new Stop TB Strategy ? Vision, Goals, Objectives

Plan to Stop TB in EEUR: Planned milestones Milestones Year Population covered by DOTS services (%) TB cases accessing quality-assured culture and drug susceptibility testing (%) Population covered by adequate MDR-TB management services. (%) Countries implementing collaborative TB/HIV activities (%) Countries with TB care in prisons of equivalent standards than outside (%) Countries where TB care is integrated at primary health care level (%) Countries where communities are involved to ensure quality TB care (%)

What are the main challenges ? 1.DOTS not yet fully expanded and of high quality everywhere 2.TB/HIV, especially in Africa, and MDR-TB, especially in former USSR and China 3.Weak health systems and services impeding proper TB control and care 4.Not all practitioners engaged 5.Communities un-aware and un-involved 6.Research not producing yet new tools and outside of the interest of TB "controllers"

Western and Central Europe l Today, mainly sexual transmission in Western and Central Europe l Exceptions: significant IDU epidemics in ESP, POR, ITA, SWI, POL l 25-65% of all cases are among MSM l Up to 75% of all heterosexual cases are among immigrants from high prevalence countries and women are >50% of all heterosexual cases l Vulnerable Groups: MSM & immigrants, specially immigrant women

Eastern Europe l Mainly IDU related transmission in Eastern Europe l 68-85% of all cases are male l Up to 30% of infected females are IDU and 50% are partners of IDU l 30-50% of all HIV infections are among those under 25 years l Vulnerable Groups: IDU, sex workers, prisoners, ethnic minorities, migrants
