Console Mission concerns Soil-transmitted helminth infections

These diseases are transferred through Water, Soil and Vector as follows.

Water born:

  1. Schistosomiasis (Snail Fever) (Estimated global prevalence: 200-600 million)
  2. Dracunculiasis (Guinea Worm Infection) (Estimated global prevalence: over 500, near eradication)


  1. Ascariasis (Roundworm Infection)
    Estimated global prevalence: 800-900 million
  2. Hookworm Infection (Estimated global prevalence: 600-700 million)
  3. Trichuriasis (Whipworm Infection) (Estimated global prevalence: 500-600 million)


The most common vectors are insects however other vectors can be animal or human transmission.

  1. Lymphatic Filariasis (Elephantiasis) (Estimated global prevalence: 100 million)
  2. Dengue (Estimated global prevalence: 50-100 million)
  3. Food-borne Trematodiases (Estimated global prevalence: 50-60 million)
  4. Onchocerciasis (Estimated global prevalence: 20-30 million)
  5. Trachoma (Estimated global prevalence: 20 million)
  6. Leishmaniasis (Estimated global prevalence: 10 million)
  7. Chagas Disease (Estimated global prevalence: 10 million)
  8. Cysticercosis (Estimated global prevalence: 2-3 million)
  9. Leprosy (Estimated global prevalence: 0.5 million)\
  10. Echinococcosis (Estimated global prevalence: 0.3 million)
  11. Rabies (Estimated global prevalence: <0.1 million)
  12. Human African Trypanosomiasis (Estimated global prevalence:<0.1 million)
  13. Buruli Ulcer (Estimated global prevalence: <0.1 million)
  14. Yaws and Endemic Treponematoses (Estimated global prevalence: not determined)

Why Focus in NTDs

  • It is parasitic and bacterial infections that affect over a billion of the world’s poorest people – that’s one sixth of the world’s population!
  • These diseases cause blindness, disabilities and disfigurements trapping infected people in a cycle of poverty and limiting their ability to work, attend school or even care for their families.
  • The presence of NTDs increases susceptibility to other diseases (HIV).
  • They are neglected diseases yet they are curable and preventable
