  2. A Neglected Tropical Disease (NTD) But it’s completely preventable!

  3. Guinea Worm Disease (GWD) is an ancient disease. • Possibly the fiery serpent referenced in the Old Testament • “Affliction of little dragons”

  4. GWD is caused by Dracunculusmedinensis—a nematode http://www.gefor.4t.com/concurso/parasitologia/dracunculus.gif CDC

  5. GWD is mainly found in Sub-Saharan Africa. WHO

  6. Dracunculusmedinensishas only 1 intermediate host, the copepod Cyclops. CDC

  7. GWD is asymptomatic a year after infection.

  8. The emergence of the worm is excruciating. • Blister and/or ulcer • Pain and Swelling • Burning Sensations • Emergence of Worm http://www.science.smith.edu/departments/Biology/SWILLIAM/fgn/pnb/dracmed.html http://www.pasozyty.com.pl/Nitkowiec-podskorny-Filaria-medinensis.html

  9. Only treatment is wrapping the worm around a stick. http://www.snl.no/dracunculiasis http://www.scielosp.org/scielo.php?script=sci_arttext&pid=S0042-96862009000900005&lng=pt&nrm=iso

  10. Prevention is the key! • How? - Drink Clean Water - Don’t Contaminate Water - Filters - Education - Insecticides (ex: Abate®) Carter Center Carter Center

  11. GWD hampers the development of communities. • GWD accounts for 60% of school absences • “Disease of the Empty Granary”

  12. "Hopefully Guinea worm will be the first parasitic disease ever eradicated. If and when that happens, we will have done it without a drug and without a vaccineto treat or prevent the disease. If we can do that, it will be one of the greatest achievements in public health."—Dr. Ernesto Ruiz-Tiben, director, Guinea Worm Eradication Program

  13. Eradication efforts have been quite successful! WHO WHO WHO

  14. Since 1986, the number of cases has dropped by 99% WHO

  15. Hopefully this disease will be the 2nd disease to be completely eradicated
