1. Neglected Tropical Diseases: an Overview Department of Control of Neglected Tropical Diseases World Health Organization

2. Neglected Tropical Diseases Protozoan Infections Leishmaniasis (VL, CL and MCL) Human African trypanosomiasis (sleeping sickness) Chagas disease Helminth Infections Soil-transmitted helminth infections Ascariasis-Trichuriasis-Hookworm Lymphatic filariasis (elephantiasis) Onchocerciasis (river blindness) Schistosomiasis Dracunculiasis (guinea-worm disease) Cysticercosis and other zoonotic helminthiasis Viral Infections Dengue & dengue haemorrhagic fever Bacterial Infections Leprosy Trachoma Buruli ulcer

4. Global distribution of NTDs

5. Countries affected by NTDs by income group

7. Annual deaths due to NTDs Revised estimates (The Lancet) Schistosomiasis 150,000 – 200,000 Leishmaniasis 100,000 Trypanosomiasis 100,000 Hookworm 65,000 Ascariasis/Trichuriasis 35,000 Dengue (DHF) 20,000 Chagas Disease 14,000 Leprosy 6,000 LF 0 Onchocerciasis 0 Trachoma 0 Total > 500,000

8. Health and poverty Ill health is both a cause and a consequence of poverty: sick people are more likely to become poor and the poor are more vulnerable to disease and disability Good health is central to creating and sustaining the capabilities that poor people need to escape from poverty Good health is not just an outcome of development: it is a way of achieving development

9. Neglected tropical diseases (NTDs): a right-to-health issue NTDs almost exclusively affects poor and marginalized people in low-income countries, in rural areas and settings where poverty is widespread Discrimination is both cause and consequence of NTDs Health interventions and research and development have long been inadequate and under funded and the picture has changed only in recent years Some of the essential drugs against NTD are now available but other are still inadequate or unavailable

11. Buruli ulcer, Chagas disease, human African trypanosomiasis, leishmaniasis… Affected populations are the poorest and most isolated Different epidemiological patterns – difficult to detect with a unified approach Diagnostic procedures and case management are expensive, difficult to implement in resource-limited field settings and require expertise The diseases cannot benefit from preventive treatment

18. WHO and its partners propose a new approach Focus on populations to improve access to essential interventions Integrate "strategies" to improve effectiveness Education, environment, local empowerment core for success All-round care, no "bits and pieces" Preventive chemotherapy on large scale PHC reinforcement, capacitating and development Focused interventions and innovation Empowering peripheral system through training and equipment Advocate for access to care and mainstream society for the neglected Measure diseases and development indicators

19. Lymphatic filariasis (LF)

20. Buruli ulcer

21. Dengue and DHF

22. Guinea-worm disease

23. Hookworms

24. Human African trypanosomiasis

25. Leishmaniasis

26. Leprosy

27. Schistosomiasis

28. Trachoma
