Presence of Dracunculiasis in humans has been documented for centuries
http://thedailyomnivore.net/2010/07/17/rod-of-asclepius/
Carolus Linnaeus postulated that the “fiery serpents” were actually parasitic worms

The disease is caused by Dracunculus medinensis
which can grow to a meter long

The worms use two hosts

Symptoms include allergy-like reactions and the formation of a blister

Diagnosis is purely visual and definite only when the head emerges
http://www.who.int/dracunculiasis/home_example/en/index.html
Treatment consists of removal of the worm

Dracunculiasis does not kill directly but leaves patients vulnerable to infection for weeks resulting
in loss of productivity and sometimes death
Prevention is achieved through education and avoiding contaminated water

The Carter Center is the primary organization behind the eradication of the disease

CDC, UNICEF and WHO have also contributed to the 99.9% decrease in worldwide cases since 1986
In 1986, 21 countries saw cases of Guinea Worm Disease, now only 4 do
