- diagnosis is easy and unambiguous (it relies on visual recognition of the emerging worm);
- the intermediate host of D. medinensis (Cyclops spp.) is not airborne (like a mosquito) but restricted to stagnant water bodies;
- control interventions are simple, cost effective and relatively easy to implement;
- the disease has limited geographical distribution and transmission is seasonal;
- there is no known animal reservoir.
- political commitment from governments is available;
- several countries in Africa, Asia and the Middle East have successfully eliminated the disease;
The eradication strategy recommended by WHO in collaboration with its principal partners (UNICEF, CDC and The Carter Center) involves the following approaches:
- mapping of all endemic villages and establishing community-based surveillance systems in every known endemic village, with immediate detection and reporting of all cases, supervision and integration of surveillance for other major preventable diseases. More details;
- implementing effective case containment measures in all endemic villages. More details;
- implementing specific interventions such as ensuring access to safe water, health education, community mobilization, filters and providing vector control of potential unsafe water sources with temephos insecticide (Abate®);
- reporting on a regular basis, even if zero cases, and maintaining global and national dracunculiasis databases to monitor the epidemiological situation;
- consolidating advocacy for eradication of the disease;
- managing the certification process for global eradication country by country.
