5 WHO HAT elimination strategy: Objectives Goal of WHO NTD Roadmap: To eliminate gambiense HAT as a public health problem by This is an intermediate step, defined as <1 new case in 10,000 inhabitants in at least 90% of foci, with < 2,000 cases reported annually at continental level. 5

Final goal of WHO and DEC and according to NTD STAG recommendations: "To interrupt transmission of gambiense HAT" by 2030 This is a sustainable final step, defined as reduction to zero of the incidence of infection caused by gambiense HAT in endemic countries Continued actions will be required to prevent re-establishment of the disease. 7

13 Gambiense HAT elimination strategy: Methods There are four classical HAT control elements: Active case-finding through mobile teams Passive case-finding integrated in fixed health facilities Vector control to reduce tsetse populations Management of detected cases 13

15 Conclusions - Much progress has been made in the fight against HAT - The sustainable elimination of HAT looks like a challenging but feasible objective - The coordination of the interventions is crucial to reach the proposed objective - But the road is not easy and the final line of the struggle is not in sight just yet - The epidemiological situation of HAT is not homogeneous and therefore the strategies have to be adapted to the different scenarios 15
