How did Nigeria eradicate guinea worm disease?
In 1988, when Nigeria reported more than 650 000 cases of guinea-worm disease, the Government launched an eradication programme following a World Health Assembly Resolution that called for the disease’s global eradication.

Many communities affected by Guinea worm disease, however, lack access to clean drinking water. In those instances, any water used for drinking or cooking should be filtered.
How has guinea worm disease been reduced?
The Guinea Worm Eradication Program is wiping out this ancient disease mainly through community-based interventions to educate and change behavior, such as teaching people to filter all drinking water and preventing transmission by keeping anyone with an emerging worm from entering water sources.
How do you control the vectors of Guinea worm?
Vector Control A vector is an organism that carries or transmits disease. The vector for GWD is the copepod. To control this vector, the GWEP puts a measured amount of the approved chemical temephos (ABATE®*) into the water sources that are suspected or known to be contaminated with Guinea worm-infected copepods.
How do you stop a worm infestation?

- deworm pet dogs and cats regularly.

What is guinea worm disease and treatment?
When the Guinea worm is ready to come out of the body, it creates a painful burning blister on the skin. The blister eventually ruptures, exposing the worm.

Where is Guinea worm disease found?
When The Carter Center began to provide technical and financial assistance to national eradication programs in 1986, Guinea worm disease was found in 20 countries in Africa and Asia. Today the disease remains in six countries, all in Africa: Sudan, Ghana, Mali, Ethiopia, Nigeria, Niger.
How does the Guinea worm infection hurt the people who have it?
About a year after infection, a painful blister forms – 90% of the time on the lower leg – and one or more worms emerge accompanied by a burning sensation. To soothe the burning pain, patients often immerse the infected part of the body in water.
How do people get infected with Guinea worm?
People become infected with Guinea worm by drinking water from ponds and other stagnant water containing copepods (tiny “water fleas” too small to be clearly seen without a magnifying glass) that carry the Guinea worm larvae. The larvae are eaten by the copepods that live in these water sources.
What are the challenges to eradication of the guinea worm?
A challenge to eradication has been the emergence of numerous Guinea worm infections in animals, mainly domesticated dogs in Chad. Guinea worm infections were first detected in animals in 2012. Most of those infections were believed linked to dogs’ consumption of fish and fish entrails containing Guinea worm larvae.
What is Guinea worm disease?
Guinea worm disease is caused by the parasitic worm Dracunculus medinensis, commonly called Guinea worm. The way the worm gets into the body and makes people sick is fairly complex, and it all starts with water fleas. These small crustaceans (known as copepods or water fleas) live in stagnant water and eat the Guinea worm larvae.
How do you treat a guinea worm infection?
De-worming medications used for other parasitic infections don’t appear to work to treat Guinea worm infections or prevent symptoms from occurring. Instead, treatment typically involves removing the worm through a long and painstaking process. The infected body part is submerged in water to coax the worm into peeking out of the wound even further.
