Shift in Perspective for Infectious Disease Control (Porter et al 1999 Health Policy and Planning 14: ) From: Disease specificity and verticality Standardised interventions Short term orientation Emphasis on product/targets To: Integrated/ Horizontal linkages Flexibility/context sensitivity Longer term objectives/sustainability Emphasis on process
Shift in Perspective for Infectious Disease Control (Porter et al 1999 Health Policy and Planning 14: ) From: Limited to health sector Focus on individual risk Operating without reference to global processes Working on behalf of populations To: Linking multiple sectors Understanding social vulnerability: risk in the context of everyday life Taking globalization as referent and context Working in partnership with communities

Global TB Control Targets: the theory 2015: 50% reduction in TB prevalence and deaths 2050: elimination (<1 case per million population) 5-10% declining incidence per year: – 70% detection rate – 85% successful treatment
Global TB Control Targets: the reality Case detection rate 61% globally in % in Africa 52% in European/Eastern Mediterranean regions 2/3 of missing cases are in China, India, Africa Treatment success rate 84.6% globally 70% in Eastern Europe 76% in Africa
